Instrument Model Number

ID? - Returns a string of the instrument identification. The string will contain the model number.
When in Remote Language compatibility mode the query will return the model number of the emulated
instrument, when in any other mode the returned model number will be that of the actual hardware.

Operation Complete

The *OPC command sets bit 0 in the standard event status register (SER) to "1" when pending
operations have finished, that is when all overlapped commands are complete. It does not hold off
subsequent operations. You can determine when the overlapped commands have completed either by
polling the OPC bit in SER, or by setting up the status system such that a service request (SRQ) is
asserted when the OPC bit is set.
The *OPC? query returns a "1" after all the current overlapped commands are complete. So it holds off
subsequent commands until the "1" is returned, then the program continues. This query can be used to
synchronize events of other instruments on the external bus.

Query Instrument Options

Returns a string of all the installed instrument options. It is a comma separated list with quotes, such as:
"503,P03,PFR".
To be IEEE compliant, this command should return an arbitrary ascii variable that would not begin and
end with quotes. But the quotes are needed to be backward compatible with previous SA products and
software. So, the actual implementation will use arbitrary ascii. But quotes will be sent as the first and
last ascii characters that are sent with the comma-separated option list.

*IDN?
*IDN? Returns instrument identification information, such as:
Agilent Technologies,N9020A,US01020004,A.01.02
Prior to A.02.00
*OPC
*OPC?
INIT:CONT 0 Selects single sweeping.
INIT:IMM Initiates a sweep.
*OPC? Holds off any further commands until the sweep is complete.
Not global to all remote ports or front panel. *OPC only considers operation
that was initiated on the same port as the *OPC command was issued from.
*OPC is an overlapped command, but *OPC? is sequential.
