SIM
Sets the output for current simulation. This command also switches the calibrator into mA
simulation mode. A number and a unit must be entered after the command. For example:
SIM 5 MA sets the current simulation at 5 mA
SIM?
Returns the output of the current simulation. With the example above, the output would be:
5.000000E-03, A
TRIG
Starts and stops the pulse train when the calibrator is in pulse mode. The parameters of the
pulse train are set by commands PULSE_CNT, and FREQ_LEVEL. Entering TRIG initializes
the train. Entering the command while the pulse train is running stops it.
TRIG?
Returns TRIGGERED if the pulse train is running, and returns UNTRIGGERED when the pulse
train is not running. Returns NONE when the calibrator is not in pulse mode.
VAL?
Returns the value of any measurement taking place on the display. For example, if the display
is measuring 10V, then VAL? will return:
1.000000E+01, V
V_RANGE
Sets the voltage range of the calibrator. DCV for the voltage range and DCMV for the
millivolts range.
V_RANGE?
Returns DCV or DCMV
