Software
Complete the following steps to install Calibration Executive:
1. Make sure that your computer and monitor are powered on and
that you have installed Windows 2000/NT/Me/9x.
2. Close all open applications.
3. Insert the installation CD into the CD-ROM drive.
4. Choose the Run option from the Start menu on the desktop task bar.
5. In the command line box, type x:\setup.exe(where x is the letter
of the CD-ROM drive you are using), and click OK.
6. Follow the instructions that appear in the dialog boxes.
The setup program installs Calibration Executive as well as
the associated files listed in Table 3.

Follow these guidelines to optimize the connections and the environment
during calibration:
•
Keep connections to the NI 5102 short. Long cables and wires act as
antennae, picking up extra noise that can affect measurements.
•
•
Use a 50 Ω BNC coaxial cable for all connections to the device.
Keep relative humidity between 10 and 90%, noncondensing,
or consult your device hardware manual for the optimum relative
humidity.
•
•
Maintain the temperature at 25 °C.
Allow a warm-up time of at least 15 minutes to ensure that the
measurement circuitry of the 5102 is at a stable operating temperature.

Calibration Procedures
This section explains how to set up and run the Calibration Executive
procedure.
Using the Wavetek 9500 in automated mode, the calibration procedure
takes approximately ten minutes. In manual mode, the procedure takes
approximately 30 minutes.
Using the alternative instruments in automated mode, the calibration
procedure takes approximately 20 minutes. In manual mode, the procedure
takes approximately 40 minutes.
Connecting Your Calibrator, DMM, and NI 5102
The calibration procedure steps you through the connections between the
calibrator, function generator, DMM, and NI 5102.
Note You do not need a function generator or a DMM if you are using the Wavetek 9500.
Running the Calibration Executive Procedure
To run the Calibration Executive calibration procedure, complete the
following steps:
1. Launch Calibration Executive and follow the instructions in the in the
Calibration Configuration Wizard to load the NI 5102 calibration
procedure. Refer to Chapter 1, Introduction to Calibration Executive,
in the Calibration Executive Software User Manual if you need more
information on configuring and loading a calibration procedure.
2. When prompted by Calibration Executive, enter information about the
installed hardware, such as the calibrator, function generator, and
DMM.
Note If you are using the Wavetek 9500, you will not need a function generator or a
DMM, so you can leave noneselected in the list boxes for Selected Generator
Information, Selected DMM Information, and Available Addresses. You must also
enter N/A in the appropriate fields for the tracking numbers and calibration due dates
before you can proceed. The calibration report does not include any of this extra
information if you are using the Wavetek 9500.
3. When the procedure is loaded, click Run Procedure to begin. The
procedure prompts you to enter the device number, which is the
number assigned by Measurement & Automation Explorer (MAX).
4. Follow any instructions you receive from Calibration Executive.
