:DISK:SPARameter:RECall
Command Syntax
:DISK:SPARameter:RECall
Description
Loads an S-parameter file into the destination S-parameter memory. To select the destination S-parameter memory, use the :DISK:SPARameter:RECall:DESTination command. To specify the S-parameter file, use the :DISK:SPARameter:LFName command. All S-parameters contained in the file will be loaded into the S-parameter memory. The default folder for S-parameter files is %USER_DATA_DIR%\S-Parameter Data. S-parameter memory is available in TDR/TDT, Eye/Mask, and Oscilloscope modes. It is not available in Jitter mode.
To load into memory all currently available S-parameters from another S-parameter memory or from a DUT in TDT/TDT mode, use the :TDR:SPMemory:LOAD:SOURce command.
When importing S-parameters from a file, the frequency spacing in the file must be uniform or the file will not be loaded into memory.
Requires FlexDCA revision A.05.00 and above.
