TRACe Subsystem Commands
TRACe[:DATA][:Y][:POWer] TRATRBTRCTRDTRETRF,<data_block> <numeric_value>{,<numeric_value>}
Sets the Y-axis data points for the trace. The number of Y-axis data points is determined by the TRACe:POINts setting. If a single numeric value is given, all of the Y-axis data points will be set to that value. If more than one value is sent, the trace length will be set to the number of values sent.
This command should be used where trace data represents power. The trace data format to be used with this command is determined by the FORMat sub- system.
TRACe[:DATA][:Y]:RATio TRATRBTRCTRDTRETRF,<data_block> <numeric_value>{,<numeric_value>}
Sets the Y-axis data points for the trace. The number of Y-axis data points is determined by the TRACe:POINts setting. If a single numeric value is given, all the Y-axis data points will be set to that value. If more than one value is sent, the trace length will be set to the number of values sent.
This command should be used when the trace data represents a power ratio (unitless number). The trace data format to be used with this command is determined by the FORMat subsystem.
TRACe:EXCHange TRA,TRBTRCTRDTRETRF
TRACe:EXCHange TRB, TRC
Exchanges both the X-axis and Y-axis data of the two traces. The only trace pairs that can be exchanged are TRA with any trace, and TRB with TRC. Specifying any other trace will generate an “Illegal parameter value” error.
The TRACe:FEED:CONTrol of the two traces is set to NEVer before the data is exchanged. Both X-axis and Y-axis data will be exchanged. After the data is exchanged, the TRACe:FEED:CONTrol of the two traces is left at NEVer.
Changing the X-axis data in a trace used in an expression (CALCulate:MATH:EXPRession) may cause an error in the expression if the X-axis data in the operands of the expression no longer match.
