The state file to load before running a calibration.

There is no default value, but it is not required.

Setting this value will put the PNA in a known state before calibrating.

It is recommended and good practice to load the calibration setup before and save it after (see SaveFilename) the calibration is run. This way the state prior to running a calibration is then loaded before each calibration and the state that will be used for running a measurement can be saved after the calibration is completed.

The filename must include the extension to determine the type of state file to be recalled. See Keysight explanation: saving and recalling state files.

  • *.csa - save Instrument state and actual Cal Set data (cal/state archive)
  • *.cst - save Instrument state and a link to the Cal Set data.
  • *.sta - save Instrument state ONLY (no calibration data)
  • *.cal - save actual Calibration data ONLY (no Instrument state)

Note: If a directory path is provided in the name then the file is searched for in that directory, otherwise the file is searched for in the directory specified by the key DirectoryToUse.

This key corresponds with the PNA SCPI command "MMEMory:LOAD[:<char>] <file>" parameter as explained in the Keysight Documentation
