Select FAST or SELECT signal source Configure switch 1 - FAST will be the highest dynamic capture. SELECT will reflect the low pass filter selection on the main 3700 Analog Controls. 3.
- Page 36 Peak Capture Response The Peak Capture of the analog signal is performed using “capacitive” memory. This technique is very repeatable and does not involve digital sampling errors. It does, however result in a millivolt/second “leak rate” after the initial “capture” which varies depending on the Peak Capture cycle rate, amplitude of the analog signal and the wave shape of the signal being monitored.
