TRACe Subsystem Commands

TRACe[:DATA]:X:STARt? TRATRBTRCTRDTRETRF

Returns the start value for the X-axis data for the trace. The X-axis data will be evenly spaced points from STARt to STOP. The number of points is determined by the TRACe:POINts setting.

TRACe[:DATA]:X:TIME:SSTop TRATRBTRCTRDTRETRF <numeric_value>[SMSUS]

This command sets the start and stop values for the X-axis data for the trace and sets the X-axis type to TIME. The first <numeric_value> corresponds to the start, and the second corresponds to the stop. If the stop value is greater than the start value, a “Data out of range” error will be generated. The X-axis data will be evenly spaced points from start to stop. The number of points is determined by the TRACe:POINts setting. If the trace has an expression defined, this expression will be cleared when changing the X-axis start/stop.

Changing the X-axis data in a trace used in an expression (CALCulate:MATH:EXPRession) by another trace may cause an error in the expression if the X-axis data in the operands of the expression no longer match.

TRACe[:DATA]:X:TYPE? TRATRBTRCTRDTRETRF

This query reads the X-axis type for the trace. The X-axis will be WAV for a trace acquired in a normal span, or TIME for a trace acquired in zero span.

The trace names defined for the instrument are: TRA, TRB, TRC, TRD, TRE, and TRF. Specifying any other will generate an “Illegal parameter value” error.
