2 Programming the Test Set
Common Commands
2. Commands such as, *OPC/*OPC?/*WAI/*RST used to be global. They considered front panel
operation in conjunction with the GPIB functionality. Now they are evaluated on a per channel
basis. That is, the various rear panel remote ports and the front panel i/o are all considered
separately. Only the functionality initiated on the port where the *OPC was sent, is considered for
its operation.
3. *OPC used to hold off until the operation bits were cleared. Now it holds off until all overlapping
commands are completed. Also, earlier instruments did not wait for completion of all processes,
only the ones identified here (in the STATus:OPERation register):
Calibrating: monitored by PSA, ESA, VSA (E4406A)
Sweeping: monitored by PSA, ESA, VSA (E4406A)
Waiting for Trigger: monitored by PSA, ESA, VSA (E4406A)
Measuring: monitored by PSA and ESA (but not in all Modes).
Paused: monitored by VSA (E4406A).
Printing: monitored by VSA (E4406A).
Mass memory busy: monitored by VSA (E4406A).
Initial S/W Revision
Prior to A.02.00
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.
Remote Command
*OPT?
Initial S/W Revision
Prior to A.02.00
Recall Instrument State
This command recalls the instrument state from the specified instrument memory register.
•
If the state being loaded has a newer firmware revision than the revision of the instrument, no state is
recalled and an error is reported
•
If the state being loaded has an equal firmware revision than the revision of the instrument, the state
will be loaded.
•
If the state being loaded has an older firmware revision than the revision of the instrument, the
instrument will only load the parts of the state that apply to the older revision.
Remote Command
*RCL <register #>
Example
*RCL 7 Recalls the instrument state that is currently stored in register 7.
