Signal Commands
IVMD(?) { VOLTage | CURRent | i }
The IVMD i command sets the signal input to voltage (i=0) or current (i=1).
Example
IVMD VOLT Set the signal input to voltage
IVMD VOLTAGE
IVMD 0
IVMD?
Returns the signal input i
ISRC(?) { A | A−B | i }
The
ISRC i
command sets the voltage input mode to A (i=0) or A−B (i=1).
Example
ISRC
A−B
Set the
voltage input to A−B
ISRC 1
ISRC?
Returns the voltage input mode i
ICPL(?) { AC | DC | i }
The ICPL i command sets the voltage input coupling to ac (i=0) or dc (i=1).
Example
ICPL DC Set the voltage input coupling to dc
ICPL 1
ICPL?
Returns the voltage input coupling mode i
IGND(?) { FLOat | GROund | i }
The IGND i command sets the voltage input shields to float (i=0) or ground (i=1).
Example
IGND FLO Set the voltage input shields to float
IGND FLOAT
IGND 0
IGND?
Returns the voltage input grounding mode i
IRNG(?) { 1Volt | 300Mvolt | 100Mvolt | 30Mvolt | 10Mvolt | i }
The IRNG i command sets the voltage input range to 1 V (i=0), 300 mV (i=1),
100 mV (i=2), 30 mV (i=3) or 10 mV (i=4).
Example
IRNG 1V Set the voltage input range to 1 V
IRNG 1VOLT
IRNG 0
IRNG?
Returns the voltage input range i
