*SRE 0..255 - Service Request Enable
Sets the Service Request Enable Register bits. This command determines the conditions under which a
service request is triggered.
*SRE? - Service Request Enable Query
Returns the value of the Service Request Enable Register.
*STB? - Status Byte Query
Returns the current value of the Status Byte Register.
*TRG - Trigger
Generates a BUS-trigger event. If the sensor is in the WAIT_FOR_TRG state and the source for the
trigger is set to BUS (TRIG:SOUR BUS), the sensor enters the MEASURING state. *TRG invalidates all
current measuring results. A query of measurement data following *TRG will thus always return the
measured value determined in response to *TRG.
Error messages:
-211
"Trigger ignored": No sensor is in the WAIT_FOR_TRG state.
-211
"Trigger ignored": A sensor is in the WAIT_FOR_TRG state but the trigger source is not BUS.
*TST? - Self Test Query
Triggers a selftest and returns 0 (no error found) or 1 (an error has occurred).
*WAI - Wait
Prevents the execution of new commands until one of the following criteria is met:
• All previous commands have been executed.
• A DCL command is received.
• The device is switched off and on again (power-on-reset).
