INPUT and FILTER COMMANDS
ISRC (?) {i} The ISRC command sets or queries the input configuration. The parame-
ter i selects A (i=0), A-B (i=1), I (1 MΩ) (i=2) or I (100 MΩ) (i=3).
Changing the current gain does not change the instrument sensitivity.
Sensitivities above 10 nA require a current gain of 1 MΩ. Sensitivities
between 20 nA and 1 µA automatically select the 1 MΩ current gain. At
sensitivities below 20 nA, changing the sensitivity does not change the
current gain.
IGND (?) {i} The IGND command sets or queries the input shield grounding. The
parameter i selects Float (i=0) or Ground (i=1).
ICPL (?) {i} The ICPL command sets or queries the input coupling. The parameter i
selects AC (i=0) or DC (i=1).
ILIN (?) {i} The ILIN command sets or queries the input line notch filter status. The
parameter i selects Out or no filters (i=0), Line notch in (i=1), 2xLine
notch in (i=2) or Both notch filters in (i=3).
