Remote Control - Commands
NRP2
197User Manual 1173.9140.02 ─ 07
Since *OPC? waits until all previous commands are executed, "1" is returned in all
cases. *OPC? basically functions like the *WAI command, but **WAI does not return a
response. *OPC? is preferred to *WAI because with *OPC?, the execution of com-
mands can be queried from a controller program before new commands are sent. This
avoids an overflow of the input queue when too many commands are sent that cannot
be executed.
Unlike *WAI, *OPC? must be sent at the end of a program message.
*OPT?
OPTion identification query returns a list of the options installed. The options are sepa-
rated from each other by means of commas.

R&S NRP-B1 "NRP-B1: Test generator installed"
