Operation
Specifications, cont’d
Equalize adjustment — This control is similar to a TV’s
sharpness control. The equalization adjustment compensates for
losses due to capacitance over long cable runs. The control
adjusts the peaking, through multiple turns, between 0 and +4dB.

Video output
Number/signal type ................... 7 composite video .... 6 amplified for distribution
1 buffered loop-through
Connectors .................................... 7 BNC female
Operation — With a waveform monitor connected to the far end
of one of the output cables, adjust the equalization so that the
color burst ranges between -20 IRE and +20 IRE.
Minimum/maximum levels ...... 0.4V to 2.0V p-p
Impedance .................................... 75 ohms
DC offset ....................................... 20mV maximum with input at 0 offset
If no waveform monitor is available, adjust the equalization to
restore the frequency response and achieve the best possible
image.
Sync
Standards ...................................... NTSC 3.58, NTSC 4.43, PAL, SECAM
The equalize adjustment is a 15-turn potentiometer with a soft
mechanical stop at the high or low end. If you have reached the
high or low end of the adjustment, the potentiometer makes a
clicking sound as you turn it, and no change is apparent on the
display.
General
Power ............................................. 100VAC to 240VAC, 50/60 Hz, 12 watts, internal,
auto-switchable
Temperature/humidity .............. Storage -40° to +158°F (-40° to +70°C) / 10% to
90%, non-condensing
The level and equalization adjustments affect all six output
channels simultaneously and equally. For maximum effectiveness
of the level and equalization controls, all display devices should be
connected with cables of equal length.
Operating +32° to +122°F (0° to +50°C) / 10% to
90%, non-condensing
Rack mount ................................... Yes, with optional 1U rack shelf, part #60-190-01
Enclosure type .............................. Metal
Enclosure dimensions ................. 1.75" H x 8.75" W x 9.4" D (1U high, 1/2 rack
The level and equalization adjustments have no affect on the
buffered loopout, which should not be run the long distances as
the amplified outputs.

4.4 cm H x 22.2 cm W x 23.9 cm D
(Depth excludes connectors.)
Specifications
Product weight ............................. 2.9 lbs (1.3 kg)

Equalization/gain ....................... 0dB to +4dB (over a 0.5 MHz to 8 MHz range)
Level adjust................................... -6dB to +6dB
Bandwidth .................................... 30 MHz (< 0.5dB)

Crosstalk ....................................... -50dB @ 3.58 MHz
Listings .......................................... UL, CUL
Compliances ................................. CE, FCC Class A
MTBF ............................................. 30,000 hours
Warranty ....................................... 3 years parts and labor
Specifications are subject to change without notice.
