Programming example
The following program fragment assumes that you are using analog output to monitor a 1mV
signal on the 10mV range. Analog output gain is set to 10 to increase sensitivity. Therefore, 1mV
will result in a 1V analog output. Finally, Analog Output Rel is enabled to reference the 1V
analog output to zero.
CALL SEND (7, ":syst:pres", status%)
CALL SEND (7, ":sens:volt:rang 0.01", status%)
CALL SEND (7, ":outp:gain 10", status%)
CALL SEND (7, ":outp on", status%)
CALL SEND (7, ":outp:rel on", status%)
Description
OUTPut Subsystem:
Specify gain factor (M); 1e-9 to 1e6.
Specify offset (B); –1.2 to 1.2.
Enable or disable Analog Output.
Enable or disable Analog Output Relative.
A. GAIN and OFFSet — Gain and offset changes do not take affect until the next
reading is triggered.
B. STATe — OFF (0) forces analog output to 0V immediately. ON (1) does not take
effect until next reading is triggered.
C. RELative — Sending ON (1) while Rel is enabled acquires a new Rel value.
