Clears the instrument status byte by emptying the error queue and clearing all event registers. Also cancels any preceding *OPC command or query. See Status Commands and Reading the Analyzer's Status Registers.
Sets bits in the standard event status enable register. See Status Commands and Reading the Analyzer's Status Registers.
Returns the results of the standard event enable register. The register is cleared after reading it. See Status Commands and Reading the Analyzer's Status Registers.
Reads and clears event status enable register. See Status Commands and Reading the Analyzer's Status Registers.
Returns a string that uniquely identifies the analyzer. The string is of the form "Keysight Technologies",<model number>,<serial "number>,<software revision>" .
Note: Beginning with Rev 6.01, this command now returns the software revision with 6 digits instead of 4. For example, A.06.01.02.
For 4 state CALPod support the following is required.
CCT (configurable command table) version 1.4
Controller FPGA version 8.4
Generates the OPC message in the standard event status register when all pending overlapped operations have been completed (for example, a sweep, or a Default). See Understanding Command Synchronization.
Returns an ASCII "+1" when all pending overlapped operations have been completed. See Understanding Command Synchronization
Returns a comma-separated string identifying the analyzer option configuration.
See a list of VNA options. Refer also to the option number differences between the common option numbers and those returned using this command.
See also SYST:CAP:LIC:CAT? for the installed product license and SYST:CAP:HARD:MOD:OPT? for hardware options in PXIe/USB VNAs. *OPT? does not return the hardware options for M980xA, P50xxA/B and P93xxB.
Executes a device reset and cancels any pending *OPC command or query, exactly the same as a SYSTem:PRESet with one exception: Syst:Preset does NOT reset Calc:FORMAT to ASCII. The contents of the analyzer's non-volatile memory are not affected by this command.
Before reading a status register, bits must be enabled. This command enables bits in the service request register. The current setting is saved in non-volatile memory. See Status Commands and Reading the Analyzer's Status Registers.
Reads the current state of the service request enable register. The register is cleared after reading it. The return value can be decoded using the table in Status Commands. See also Reading the Analyzer's Status Registers.
Reads the value of the instrument status byte. The register is cleared only when the registers feeding it are cleared. See Status Commands and Reading the Analyzer's Status Registers.
Returns the result of a query of the analyzer hardward status. An 0 indicates no failures found. Any other value indicates one or more of the following conditions exist. The value returned is the Weight (or sum of the Weights) of the existing conditions. For example:
If 4 is returned from *TST?, an Overpower condition exists.

Description |
Bit is set to 1 when the following conditions exist: |
0 |
1 |
Phase Unlock |
The source has lost phaselock. This could be caused by a reference channel open or a hardware failure. |
1 |
2 |
Unleveled |
The source power is unleveled. This could be a source is set for more power than it can deliver at the tuned frequency. Or it could be caused by a hardware failure. |
2 |
4 |
Not used |
|
3 |
8 |
EE Write Failed |
An attempted write to the EEPROM has failed. This is possibly caused by a hardware failure. |
4 |
16 |
YIG Cal Failed |
The analyzer was unable to calibrate the YIG. Either the phaselock has been lost or there has been a hardware failure. |
5 |
32 |
Ramp Cal Failed |
The analyzer was unable to calibrate the analog ramp generator due to a possible hardware failure. |

Prohibits the instrument from executing any new commands until all pending overlapped commands have been completed. See Understanding Command Synchronization
