Timebase:delay:scale; Timebase:href:mode - Rigol DS4000E Series Programming Manual

RIGOL
DelayRange = 14 x DelayScale.
MainScale is the main time base, refer to the :TIMebase[:MAIN]:SCALe command; MainOffset is the
horizontal position (normal sweep), refer to the :TIMebase[:MAIN]:OFFSet command; DelayScale is the
horizontal time base of the delayed sweep, refer to the :TIMebase:DELay:SCALe command.
Return Format
The query returns the horizontal position of the delayed sweep in scientific notation.

:TIMebase:DELay:SCALe

Syntax
:TIMebase:DELay:SCALe <scale>
:TIMebase:DELay:SCALe?
Description
Sets or queries the horizontal time base of the delayed sweep. The default unit is s/div.
Parameter
Name Type
<scale> Real
Return Format
The query returns the horizontal time base of the delayed sweep in scientific notation.

:TIMebase:HREF:MODE

Syntax
:TIMebase:HREF:MODE <href>
:TIMebase:HREF:MODE?
Description
Sets or queries the horizontal reference.
Parameter
Name Type
<href> Discrete
Remarks
CENTer: when the horizontal time base is modified, the waveform displayed will be expanded or

compressed horizontally relative to the screen center.
TPOSition: when the horizontal time base is modified, the waveform displayed will be expanded or
compressed horizontally relative to the trigger position.
USER: when the horizontal time base is modified, the waveform displayed will be expanded or
compressed horizontally relative to the user-defined reference position (refer to
the :TIMebase:HREF:POSition command).
Only when the horizontal time base mode is Y-T (refer to the :TIMebase:MODE command) and the

delayed sweep is off (refer to the :TIMebase:DELay:ENABle command), can this command be valid.
Return Format
The query returns CENT, TPOS, or USER.
2-190
Range
The minimum value of <scale> is related to the current
sample rate. It must satisfy the formula (1x50/real-time
sample rate x 1/40) and should not be less than 2 ns. The
maximum value of <scale> is the current main time
base.
Range
{CENTer|TPOSition|USER}
Chapter 2 Command System
Default
500 ns/div
