AC Gain
If the AC Gain control is set to Manual (using the Input Setup menu), then this
control allows it to be adjusted from 0 dB to 90 dB in 10 dB steps, although not all
settings are available at all full-scale sensitivity settings.

Time Constant
The time constant of the output filters is set using this control. The settings between
10 µs and 640 µs are in a binary sequence and apply only to outputs at the rear panel
FAST X and FAST Y connectors. Settings between 5 ms and 5 ks are in a 1-2-5
sequence and apply only to all the other instrument outputs.
