Relay Matrix Switch Command Reference 65Chapter 3
IEEE 488.2 Common Commands Quick Reference
The following table lists the IEEE 488.2 Common (*) commands that
apply to the Relay Matrix Switch modules. For more information on
Common Commands, see the ANSI/IEEE Standard 488.2-1987.
Command Command Description
*CLS Clears all status registers (see STATus:OPERation[:EVENt]?) and clears error queue.
*ESE <unmask> Enables Standard Event.
*ESE? Enables Standard Event Query.
*ESR? Standard Event Register Query.
*IDN? Instrument ID Query; returns identification string of the module.
*OPC Operation Complete.
*OPC? Operation Complete Query.
*RCL
<n> Recalls the instrument state saved by *SAV. You must reconfigure the scan list.
*RST Resets the module. Opens all channels and invalidates current channel list for scanning. 
Sets ARM:COUN 1, TRIG:SOUR IMM, and INIT:CONT OFF.
*SAV
<n> Stores the instrument state but does not save the scan list.
*SRE
<unmask> Service request enable, enables status register bits.
*SRE? Service request enable query.
*STB? Read status byte query.
*TRG Triggers the module to advance the scan when scan is enabled and trigger source is
TRIGger:SOURce BUS.
*TST? Self-test. Executes an internal self-test and returns only the first error encountered. 
Does not return multiple errors. The following is a list of responses you can obtain where
“cc” is the card number with the leading zero deleted.
+0 if self test passes.
+cc01 for firmware error.
+cc02 for bus error (problem communicating with the module).
+cc03 for incorrect ID information read back from the module's ID register.
+cc10 if an interrupt was expected but not received.
+cc11 if the busy bit was not held for a sufficient amount of time.
*WAI Wait to Complete.
