Chapter 4 Remote Interface ReferenceStatus Reporting Commands*OPCSet the “operation complete” bit (bit 0) in the Standard Event registerafter the previous commands have been executed. Used only in thetriggered burst mode and triggered sweep mode.*OPC?Return “1” to the output buffer after the previous commands havebeen executed. Used only in the triggered burst mode and triggeredsweep mode.*PSC {0|1}Power-on status clear. Clear the Status Byte and Standard Eventregister enable masks when power is turned on (*PSC 1). When*PSC 0 is in effect, the Status Byte and Standard Event register enablemasks are not cleared when power is turned on. The factory setting is“1” (enabled). [ Stored in non-volatile memory ]*PSC?Query the power-on status clear setting. Returns “0” (*PSC 0) or “1”(*PSC 1).*SRE Enable bits in the Status Byte enable register.*SRE?Query the Status Byte enable register. The function generator returnsa decimal value which corresponds to the binary-weighted sum of allbits set in the register.*STB?Query the Status Byte summary register. The *STB? command issimilar to a serial poll but it is processed like any other instrumentcommand. The *STB? command returns the same result as a serial pollbut the “request service” bit (bit 6) is not cleared if a serial poll hasoccurred.*WAIWait for all pending operations to complete before executing anyadditional commands over the interface. Used only in the triggered burstmode and triggered sweep mode.210
