When *OPC is sent, the OPC bit in the Standard Event Register will set after all pending
command operations are complete. When *OPC? is sent, an ASCII
“

”
is placed in the Output
Queue after all pending command operations are complete.
Typically, either one of these commands is sent after the INITiate command. The INITiate
command is used to take the instrument out of idle in order to perform measurements. While
operating within the trigger model layers, all sent commands (except DCL, SDC, IFC,
SYSTem:PRESet, *RST, *RCL, *TRG, GET, and ABORt) will not execute.
After all programmed operations are completed, the instrument returns to the idle state at
which time all pending commands (including *OPC and/or *OPC?) are executed. After the last
pending command is executed, the OPC bit and/or an ASCII
“
1
”
is placed in the Output Queue.
