HP BenchLink/Arb Components
Menu Bar
The Menu Bar contains pull-down menus. Position your cursor over a
menu item and click the mouse button to view the menu choices. You can
also use the menus by holding the Alt key and typing the underlined
letter of the menu choice (for example, Alt+F will display the File menu).
2
Toolbar
The Toolbar contains icons for quick display of dialog boxes and rapid
execution of HP BenchLink/Arb commands. The icons on the Toolbar
perform the same tasks as the pull-down menus in the Menu Bar, but do
so with a single click.
Palette Bar
The Palette Bar provides quick access to tools used in creating and
editing waveforms. Icons allow you to insert new waveform segments into
the active waveform window, edit segments already in the waveform
window, and to change the view of the waveform by zooming in or out.
Waveform Edit Windows
Waveforms created in HP BenchLink/Arb are displayed in waveform edit
windows. Waveforms consist of one or more segments which can be
created by inserting standard waveshapes, freehand drawing, line
drawing, and performing mathematical operations. Segments can be
combined to create virtually any arbitrary waveform you may need.
Wave View Window
The Wave View window allows you to view the entire waveform while
you are creating and editing individual segments in the active waveform
edit window. Any changes made to the waveform will be reflected in the
Wave View window. For convenience, the Wave View window can be
placed anywhere on your computer screen.
The Wave View window contains a sampled representation of the
waveform, and as such, cannot display every waveform detail. Rather
than a precise rendering of the waveform, the Wave View window gives a
general ‘overview’ of the waveform.
Status Bar
The Status Bar provides brief descriptions of the Menu Bar and Toolbar
items currently selected and provides specific waveform information
depending upon the application mode. It appears at the very bottom of
the HP BenchLink/Arb screen and dynamically changes as the various
menu commands or modes are selected.

Chapter 3 Using HP BenchLink/Arb
About Arbitrary Waveforms
This chapter describes procedures, components, and features you will use
in HP BenchLink/Arb.
About Arbitrary Waveforms
The waveforms you create in HP BenchLink/Arb are a series of data
points. The first point, 0, is given a Y value between -1 and +1. The next
point has another Y value, and so on, to the maximum number of data
points in your waveform. Taken together, these points make up a
waveshape.
3
All the data points in the waveform edit window make up one function
generator output cycle. When you send the waveform to the function
generator, it will attempt to output all the points at the frequency you
specify. For example, if you create a waveform with 10 sine wave
segments and set a 1 kHz output frequency when you send the waveform
to the function generator, the output will appear to be a 10 kHz sine wave.
The function generator samples the data points at 40 Msamples/second.
The maximum output is determined by the sample rate divided by the
number of points. A full waveform edit window (16,000 data points)
appears to have an upper frequency limit of 2.5 kHz , since
40 Msamples/16,000 = 2500. When higher frequencies are reached, the
function generator automatically samples the points so the full wave is
output. The function generator will sample no fewer than 8 points per
waveshape. Refer to chapter 7 in the HP 33120 User’s Guide for
additional information about sampling.
When possible, you should always send the maximum number of data
points. The more data points you send, the greater the fidelity of the
function generator output. HP BenchLink/Arb contains a special
function to allow you to expand any waveform to the maximum number
of data points.
The relative amplitude (Y values) of your waveform can range from -1 to
+1. This is a ‘relative’ amplitude because the function generator output
voltage will be scaled to these values. You set the desired output
peak-to-peak voltage when you send the waveform to the function
generator. For example, a square wave in the waveform edit window
that ranges from -1 to +1 can be output as a 1 volt peak-to-peak
waveform. The +1 relative amplitude is scaled to +0.5 volts and the -1
relative amplitude is scaled to -0.5. The square wave will be centered
around 0 volts.

Chapter 3 Using HP BenchLink/Arb
About Arbitrary Waveforms
Because of this relative amplitude scaling, it is possible to create
waveforms that contain unintentional dc offsets. Consider a square wave
that ranges from +1 to -0.5. If this waveform is sent to the function
generator with a specified output voltage of 1 V peak-to-peak, the square
wave will not be centered around 0 V but will have an apparent +0.5 Volt
dc offset. The +1 relative amplitude will be scaled to +0.75 V and the -0.5
relative amplitude will be scaled to -0.25 V.
3
Where possible, your waveforms should range from +1 to -1 in the
waveform edit window. HP BenchLink/Arb contains a special function to
allow you expand the Y values to the maximum.
The Y values of the starting and ending points in your waveform can also
cause unexpected discontinuities if they are not the same value. The
function generator output will ‘jump’ from the ending value to the
starting value each cycle. For a smooth waveform output, be sure the
starting and ending values are the same.
Small discontinuities within the waveform can be removed by smoothing
the waveform. These discontinuities are common with waveforms created
by freehand or line drawing modes. HP BenchLink/Arb provides a special
smoothing function for this purpose.

Waveforms consist of one or more segments of X and Y points which can
be created in HP BenchLink/Arb in a number of ways, including drawing
the waveform in freehand mode, combining standard waveshapes,
applying mathematical operations, and importing X, Y data from other
applications. Any of these methods can be combined to create more
complex waveforms. Segments can be of many different sizes with the
total not exceeding 16,000 points per waveform.

Chapter 4 Feature and Function Reference
Waveform Edit Windows
Waveform Edit Windows
Waveforms created in HP BenchLink/Arb are displayed in waveform edit
windows. Waveforms consist of one or more segments which can be
created by inserting standard waveshapes, freehand drawing, line
drawing, and performing mathematical operations. Segments can be
combined to create virtually any waveform you may need.
Standard waveshape segments can be inserted in the waveform edit
window by clicking the appropriate icon on the Palette Bar to insert one
cycle of default parameters or by selecting the Waveforms Menu and
choosing a standard waveshape. The menu method allows you to change
parameters of the standard waveshape and preview it before it is
inserted in the window. After a segment has been inserted,
4
double-clicking on it will display the Edit Segment dialog box to display
and change its parameters. After math operations have been performed
on a standard waveshape, double-clicking will produce the Resize Data
dialog box, allowing you to expand or contract the waveshape in both
horizontal and vertical directions.
Eight different segments, created from the standard waveshapes, are
shown in the figure. The triangle wave segment has been selected and is
therefore highlighted.

Chapter 4 Feature and Function Reference
Waveform Edit Windows
The waveform edit window contains horizontal and vertical gridlines.
To change the spacing of the horizontal and vertical grid lines select
View | Grid... from the Menu Bar.
The spacing of the vertical (up/down) grid lines is directly affected by the
View | Grid... command. The horizontal spacing (left/right) of the grid
lines is automatically adjusted to standard values (such as 0, 0.25, 0.5,
0.75, or 1.0).
Grid line spacing is specified in terms of the number of screen display
pixels between grid lines. While this spacing also relates to the number of
waveform data points displayed between grid lines, the relationship is
not always one-to-one due to the effects of zooming. Six levels of zooming
are provided (0 - 5), giving the pixel-to-number-of-data-points
relationship in the following table:
4
Waveform data points
Zoom Level
per screen display pixel
(default - no zoom)
0
1
2
3
4
5
32
16
8
4
2
(fully zoomed in)
1
For example, if no zoom is in use, a spacing of 100 pixels between vertical
grid lines relates to the display of 3200 (32 X 100) waveform data points
between grid lines. At full zoom, a spacing of 100 pixels between grid
lines results in 100 (1 X 100) waveform data points between grid lines.
To adjust grid line spacing, specify the number of pixels by clicking on
the up/down arrows or type a number in the text box and click OK. Valid
grid sizes range from 50 (default) to 200 pixels.
The waveform edit window can also be displayed in normal or high
resolution viewing mode. Normal mode consists of points that have been
uniformly sampled and chosen for display. High resolution mode displays all
points of the waveform (Select View | High Resolution from the Menu
Bar). Operations on the waveform in high resolution mode will take longer
to perform because the display will be updated at a slower rate.

Chapter 4 Feature and Function Reference
Wave View Window
Several windows can be displayed at one time. All new window title bars
contain the word ‘Untitled’, and a number. When the windows are saved,
‘Untitled’ is changed to the name of the file. The total number of points
in each waveform must be a minimum of 8 points and cannot exceed
16,000 points.
Waveform Edit windows can be maximized, reduced to an icon, cascaded
or tiled. If HP BenchLink/Arb is reduced to an icon, any waveform edit
windows will also be reduced to an icon.
Wave View Window
The Wave View window allows you to view the entire waveform while
you are creating and editing individual segments in the active waveform
edit window. Any changes made to the waveform will be reflected in the
Wave View window. For convenience, the window can be placed
anywhere on your computer screen.
4
The Wave View window contains a sampled representation of the
waveform, and as such, cannot display every waveform detail. Rather
than a precise rendering of the waveform, the Wave View window gives a
general ‘overview’ of the waveform.
A zoom locator box within the Wave View window shows which part of
the overall waveform is currently displayed in the waveform edit window.
Move the zoom locator box using a click and drag motion to change the
waveform edit window display. Markers are also displayed in the Wave
View window (when enabled) to show their location relative to the
waveform edit window.

Chapter 4 Feature and Function Reference
Selection modes
Selection modes
HP BenchLink/Arb uses different selection modes for performing various
functions:
Edit Select mode. Parts or segments of the waveform can be selected by
clicking the ‘edit select’ icon found on the Palette Bar. This selection
mode allows you to highlight the desired area for editing or math
operations.
When you first enter ‘edit select’ mode and move your mouse in the
waveform edit window, the Status Bar reflects the X and Y positions of
your cursor as it moves across the window. When a portion of the
waveform is highlighted by clicking and dragging the cursor, the Status
Bar reflects the start and end points of the highlighted area and the total
number of points selected. The highlighted area can be adjusted using the
up/down and left/right arrows in the following manner:
4
• Right arrow - selects the right side of the highlighted area
• Left arrow - selects the left side of the highlighted area
• Up arrow - increases the highlighted area
• Down arrow - decreases the highlighted area
In normal viewing mode, the up/ down arrow keys may not seem
to increase or decrease the highlighted area in the waveform
edit window, yet the Status Bar indicates the change in
selection. Zooming in will display the results in a more efficient
manner.
To invalidate a highlighted selection, click past the end of the waveform
or click the ‘edit select’ icon again.
Selecting a segment. To highlight an individual segment, press the
SHIFT key and click on the segment. Continue to hold the SHIFT key to
click and select multiple segments. Double-clicking on a segment will
display the Resize Data dialog box allowing you to change the vertical
and horizontal aspects of the segment. Standard waveshape segments
will display the Edit Segment dialog box unless some form of math
operation has been performed on them.
Select all. To select the entire waveform consisting of multiple segments,
choose Edit | Select All from the Menu Bar or press SHIFT and
double-click in the waveform edit window.

Zoom
Marker mode. ‘Marker’ mode is entered by clicking the icon on the
Palette Bar or by choosing Edit | Marker Select from the Menu Bar.
This mode automatically enables the X and Y markers. Selecting either X
or Y markers (from the Edit Menu or with icons) also causes the cursor to
change to ‘marker’ mode. Move the markers using a click and drag
motion, or, for fine adjustment, the arrow keys.
While you are in ‘marker’ mode, the Status Bar reflects the location of the
X or Y marker pairs as they are positioned in the waveform edit window
and the difference between them. To exit this mode, click the ‘marker’
icon again. This disables the markers and enters the ‘edit select’ mode.
Clicking the ‘edit select’ icon will exit ‘marker’ mode and leave the
markers enabled.
4
Zoom
There are six zoom levels available. In the normal viewing mode (fully
zoomed out) one pixel of the screen equals 32 waveform data points.
Zooming in decreases the number of points equal to one pixel in multiples
of two (e.g. 32, 16, 8, 4, 2, 1). Zooming can be performed in the following
ways:
To zoom into part of a waveform, choose View | Zoom from the Menu
Bar or click the Zoom icon. The cursor will change to a magnifying glass.
Click and drag your mouse to define the area to zoom into. When you
release the mouse button, the selected area will be displayed in the active
waveform window. This process can be repeated until you are fully
zoomed in and one pixel equals one data point.
To zoom in one level at a time, choose View | Zoom In from the Menu
Bar or click the Zoom In icon. You can zoom in until you reach the level
where one pixel equals one data point.
Click the Zoom Out icon or choose View | Zoom Out from the Menu Bar
to zoom out one level at a time. You can zoom out until the entire
waveform is displayed. If you wish to zoom out and display the waveform
in one step, choosing View | View All will fit the entire waveform into
the waveform edit window.
The zoom locator box in the Wave View window outlines the
portion of the waveform currently displayed in the waveform
edit window. This box changes as you zoom in and out and can
be moved by clicking and dragging it.

X and Y Markers
X and Y Markers
Vertical (X) or horizontal (Y) markers are available in HP BenchLink/Arb
to assist you in creating and modifying waveforms. Select
Edit | X Markers or Edit | Y Markers or click their icons to display
the X or Y markers. When the markers are first displayed, your cursor
will be in the ‘marker’ mode. The markers can be moved by clicking the
mouse on any of the markers and dragging them to the desired location
or by using the left and right arrow keys. The X or Y marker positions
and the difference between the X or Y marker position is displayed in the
Status Bar at the bottom of your HP BenchLink/Arb screen. Markers can
be disabled by selecting the appropriate commands from the Edit Menu
or by clicking their icons on the Palette Bar.
4
Markers can be set and held in a specific position by clicking the
Thumbtack icon or by selecting Edit | Set Thumbtack from the Menu
Bar. Thumbtacked markers can be used to confine the editing area or to
alter a standard waveshape segment using freehand or line drawing
mode. Drawing is permitted only in the area between the markers and
must be started in the marked area. Clicking and drawing outside of this
area is ignored.
Grid
The waveform edit window contains horizontal and vertical gridlines.
To change the spacing of the horizontal and vertical grid lines select
View | Grid... from the Menu Bar.
The spacing of the vertical (up/down) grid lines is directly affected by the
View | Grid... command. the horizontal spacing (left/right) of the grid
lines is automatically adjusted to standard values (such as 0, 0.25, 0.5,
0.75, or 1.0).
Grid line spacing is specified in terms of the number of of screen display
pixels between grid lines. While this spacing also relates to the number of
waveform data points displayed between grid lines, the relationship is
not always one-to-one due to the effects of zooming. Six levels of zooming
are provided (0 - 5). Refer to the discussion on page 53 for more
information about the grid settings.

Scrolling
Scrolling
Use the vertical and horizontal scroll bars to view different portions of
the waveform. Scroll bars are needed because, in some cases, the actual
waveform physically occupies more space than the window can display at
one time. If the waveform fits in the window, no scroll bars will be
displayed.
Tick Marks (Segment Identification Markers)
Tick marks are visual aids used to identify the start and end points of a
waveform segment. They appear as inverted arrows at the top of the
waveform edit window (see the figure on page 14). To enable/disable tick
marks, select View | Tick Marks from the Menu Bar.

File Descriptions
.ARB
This file extension is used to designate an arbitrary waveform file saved
using the HP BenchLink/Arb application. The .ARB file is saved in a
proprietary binary format.
.BIN
HP BenchLink/Arb can save waveform data in IEEE-488.2 binary block
format. This format contains a file header and binary data. The waveform
data is represented in 12-bit format, sent as two bytes. The file will,
therefore, contain twice the number of bytes as waveform data points.
.CSV
The comma-separated values file format includes a point number and
corresponding relative amplitude value for each data point in the
waveform. The point and amplitude values are separated by a comma.
Point values range from 0 to 15,999 and amplitude values range from
-1 to +1.
.PRN
The PRN file format includes a point number and corresponding relative
amplitude value for each data point in the waveform. The point and
amplitude values are separated by a tab. Point values range from 0 to
15,999 and amplitude values range from -1 to +1.
