INPUTS AND OUTPUTS
Performance
Requirements
5 V p-p for a 500:1 minimum frequency
change.
T IL compatible.
All inputs protected against up to ± 42 V
(de plus peak ac) accidental input.
T T L level squarewave at programmed
frequency.
Source resistance is 600Q ; a positive
linear ramp. Amplitude is dependent on
start and stop frequency and a 5 V limit.
