XV. REMOTE COMMANDS
Introduction
Remote commands duplicate activities that can be initiated from the front panel in local
operation. Following the summary table is a complete alphabetical listing of all commands
complete with protocol details. Separate headings in the alphabetical listing provide the
parameters and responses, plus an example for each command. For information on using
commands, see "Remote Operation."
Command Summary by Function
Common Commands
Command Description
*CLS (Clear status.) Clears the ESR, the error queue, and the RQS bit in the status byte.
This command terminates pending operation complete commands (*OPC or *OPC?).
*ESE Loads a byte into the Event Status Enable register.
*ESE? Returns the contents of the Event Status Enable register.
*ESR? Returns the contents of the Event Status register and clears the register.
*IDN? Identification query. Returns the manufacturer, model number, and firmware revision
level of the Calibrator.
*OPC Enables setting of bit 0 (OPC for "Operation Complete") in the Event Status Register to
1 when all pending device operations are complete.
*OPC? Returns a 1 after all pending operations are complete. This command causes program
