Default
<n>
Discrete
1|2|3|4
--
--
Bool
OFF|ON|0|1
ON|1
Remarks
ON: sets to Auto mode. The instrument adjusts the X-axis reference value and X-axis width to an optimal
state.
OFF: sets to Manual mode. You need to set the X-axis reference value and X-axis width manually.
Return Format
The query returns 0 or 1.
Example
The following command enables the X Scale auto mode of Trace 1.
:DISPlay:DDEMod:TRACe1:X:SCALe:COUPle ON or :DISPlay:DDEMod:TRACe1:X:SCALe:COUPle 1
The following query returns 1.
:DISPlay:DDEMod:TRACe1:X:SCALe:COUPle?
:DISPlay:DDEMod:TRACe<n>:X[:SCALe]:RLEVel
Syntax
:DISPlay:DDEMod:TRACe<n>:X[:SCALe]:RLEVel <real>
:DISPlay:DDEMod:TRACe<n>:X[:SCALe]:RLEVel?
Description
Sets the X-axis reference of the selected trace.
Queries the X-axis reference of the selected trace.

<real> Consecutive Real Number
Time-Domain Data:
(-1e+12) to (1e+12)
Frequency-Domain Data:
-1THz to 1THz
0 (0 us)
/998.4375 MHz
Remarks
This command is valide only when the X-axis scale is set to Manual.
When the time-domain data source is selected, the reference unit is symbol or s; when the
frequency-domain data source is selected, the reference unit is Hz.
Return Format
The query returns the X-axis reference of the selected trace in scientific notation.
Example
The following command sets the X-axis reference of Trace 1 to 25.
:DISPlay:DDEMod:TRACe1:X:SCALe:RLEVel 25
The following query returns 2.500000000e+01.
:DISPlay:DDEMod:TRACe1:X:SCALe:RLEVel?
