90PGA Slot Card
Dual Channel Programmable
Amplifier Slot Card
For 90IP Instrumentation Platform
Description:
For use in the 90IP Instrumentation Platform,
each 90PGA slot card provides design
engineers with two channels of precision, low
noise and distortion programmable amplifiers
with up to 60 dB of adjustable gain in 0.50 dB
steps over a 1 MHz bandwidth.
Front panel mounted BNC’s offer easy access
for connection of signal input and output.
Other features include differential or single-
ended input, AC or DC-coupled input, single
ended output, LED clipping indicators and fine
adjustment of DC offset.
Features:
•
Selectable single-ended or differential
input, AC or DC coupled.
•
Gain/phase matched channels
•
LED clipping indicators
•
Memory storage for up to 9 set-ups/channel
•
Input noise 12 nV/
