*IST? - Individual Status Query
Returns the current value of the IST flag. The IST flag is described in section Æ "IST Flag and Parallel
Poll Enable Register (PPE)" on page 6.77.
*OPC - OPeration Complete
Sets the operation complete bit in the Standard Event Status Register as soon as all currently executed
commands have been completed. This bit can be used to trigger a service request. *OPC must be at
the end of a program message.
*OPC? - OPeration Complete Query
After completion of all currently executed commands, the R&S NRP writes a "1" into the output queue.
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 commands 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 at the end of a program message.
*OPT? - OPTion Query
Returns a string to the output queue containing information about all options installed.
Option Response string
1 "NRP-B1: Test generator installed"
2 "NRP-B2: Second channel interface installed"
3 "NRP-B3: Battery installed"
4 "NRP-B4: Ethernet interface installed"
5 "NRP-B5: Four channel interface installed"
6 "NRP-B6: Sensor A/B rear socket"
