– Remote operation: The CONFigure and MEASure subsystems use an optional
parameter to specify the input channel as either 1 or 2:
CONF:VOLT:DC DEF, DEF,(@FRONTl) Channel 1 operation
CONF:VOLT:DC DEF, DEF,(@FRONT2) Channel 2 operation
The SENSe subsystem uses a keyword modification to indicate the channel:
SENS1:VOLT:DC:RANG:AUTO Channel 1 operation
SENS2:VOLT:DC:RANG:AUTO Channel 2 operation
Two Channel Measurements
– Difference measurements: First, set the range and null value for each input
channel. Then, select difference measurements.
[1]
– Ratio measurements: First, set the range and null value for each input
channel. Then, select ratio measurements.
– Remote operation: use the following commands to measure or configure a
difference or ratio measurement. Set each channel to the appropriate range
and null conditions using:
[SENSe1:|SENSe2:]
VOLTage:DC
:RANGE <range>
:NULL:STATe {OFF|ON}
:NULL:VALue {<value>|MIN|MAX}
[1] The difference null is only available from the front panel.
