GENERAL INFORMATION
BASIC CONTROL
The AV-110D-PS is a DC-1 MHz variable-gain linear amplifier. The gain is variable from
0 to +15, and is adjusted by rotating the “GAIN” control.
Units with the -INV option can also be switched to inverting mode, where the gain is
variable from 0 to -15.
The required voltage input signal is applied at the “IN” connector.
This mode is illustrated below:
If the instrument has the -OS option, a DC offset in the range of of -15V to +15V (for
-OS units) or -30V to +30V (for -XOS units) may be added to each output. The total
output voltage (amplified DC offset) must remain within the range of -30V to
+30V.
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) if the
load resistance is not 50 Ohms. 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.
