GENERAL INFORMATION
BASIC CONTROL
The AV-110B-PS-D is a DC-100 kHz variable-gain linear amplifier, and the AV-110G-
PS-D is the same but with an extended bandwidth range of DC-350 kHz.
The gain of each of the two channels (designated “A” and “B”) is variable from +1 to
+100, and is adjusted by rotating the “Gain” associated control.
The required voltage input signals are applied at the “IN” connectors.
This operation is illustrated below:
If the instrument has the -OS option, a DC offset in the range of -50V to +50V may be
added to each output. A front-panel dial and switch control this offset. The total output
voltage (amplified DC offset) must remain within the range of -200 to +200V.
CABLE LENGTHS
The length of cable used to connect the load to the output of the function generator
should be less than 3 feet (1 meter), and ideally less than 18 inches (0.5 meters). At
longer lengths, the transmission line reflections caused by the cabling and the cable's
capacitance will distort the output signal and degrade the rise and fall times, particularly
if the signals with fast rise times are used.
The capacitance associated with any length of coaxial cabling will degrade the rise and
fall times of fast signals.
