Programming Commands
TRACe Subsystem Commands
:TRACe[:DATA]:X:STOP?
Returns the stop value for the X-axis data for the trace.
The X-axis data will be evenly spaced points from STARt to STOP. The num-
ber of points is determined by the TRACe:POINts setting.
Syntax
: T R A C e [ : D ATA ] : X : S T O P ? T R A | T R B | T R C | T R D | T R E | T R F
:TRACe[:DATA]:X:TIME:SSTop
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 corre-
sponds 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.
Syntax
: T R A C e [ : D ATA ] : X : T I M E : S S To p T R A | T R B | T R C | T R D | T R E | T R F
:TRACe[:DATA]:X:TYPE?
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.
Syntax
: T R A C e [ : D ATA ] : X : T Y P E ? T R A | T R B | T R C | T R D | T R E | T R F
