Query Syntax

:SPRocessN:DFEQualizer:PROPtimize:SAVE?

Description

When :SPRocess:DFEQualizer:PROPtimize is ON and :SPRocess:DFEQualizer:TAPS:AUTo is ON, causes that the optimized DFE pulse response data be saved in an ASCII text file whenever an optimization is recalculated. The optimization is recalculated when any of the following command change a setting:

• :SPRocess:DFEQualizer:TAPS:RECalculate
• :SPRocess:DFEQualizer:PROPtimize:DELay
• :SPRocess:DFEQualizer:PROPtimize:LENGth
• :SPRocess:DFEQualizer:PROPtimize:BMAX

Use the :SPRocess:DFEQualizer:PROPtimize:SAVE:FILE command to specify the file name used. The default file name is PulseResponse.txt.

The contents of the saved file is similar to the following listing:
