Measurement commands
SCPI Command Description Query
*CLS Clears the status data structures. N/A
*ESE Sets the standard event status enable register bits. Yes
*ESR? Queries the standard event status register. Query
only
*IDN? Queries the identification string. (Manufacturer information) Query
only
*OPC Causes the device to generate the operation complete message in the standard event status register
when all pending selected device operations have been finished.
Yes
*RCL <value> Restores the current settings of the device from a copy stored in local memory. N/A
*RST Performs a device reset. Configures the PLZ-U to a known condition independent from the usage
history of the device.
N/A
*SAV <value> Stores the current settings of the device to local memory. N/A
*SRE Sets the service request enable register bits. Yes
*STB? Reads the status byte and the master summary status bit. Query
only
*TRG Trigger command. This is analogous to the Group Execute Trigger interface message defined in
IEEE 488.1. See section 6.1.4.2.5 of IEEE 488.2.
N/A
*TST? Since there is no self-test function built into the PLZ-U, an ASCII character 0 is always returned in
the output queue in response to this query.
Query
only
*WAI Prevents the device from executing subsequent commands or queries until the No Operation Pend-
ing flag becomes true. (*OPC?)
