1. Setting Range
The setting range and rounding method for the TRDL command are defined as
follows, depending on the waveform acquisition and sweep time.
Trigger Mode
SINGLE, NORMAL or AUTO
STOP
• The above division value in the setting range is calculated from the following
equation.
(Setting range upper limit) = +5div × (Sweep time)
• Any value exceeding the above range is rounded to the maximum or minimum
permissible value, whichever is nearest.
2. Set resolution
The resolution is changed according to the set sweep time. The resolution is
calculated from the following equation.

TRDL
Command/Query
The TRDL command defines the horizontal position of the
trigger point in time. With the screen center defined
as zero, the time duration from this zero point to the
trigger point is set. The setting range is determined
by the timebase (TDIV). The TRDL? query returns the set
horizontal position of the trigger point.
TRDL <value>
<value>:= Trigger point setup parameter. The <DECIMAL
NUMERIC PROGRAM DATA> format is used, and the suffix
is also valid.
The range of <value>:
<value> := -500s to +5div (Time/div := 50s/div to
10ms/div)
<value> := -5s to +5div (Time/div := 5ms/div to
10us/div)
<value> := -5ms to +5div (Time/div := 5us/div to
500ps/div)
<value> := -500s to +750s (Trigger mode is STOP)
See Remarks for detail.
TRDL?
<value>
<value>:= The <NR3 NUMERIC RESPONSE DATA> format is
used. The currently set trigger point is input here.
TRDL reports command-execution error (CME) when
<value> is not a <DECIMAL NUMERIC PROGRAM DATA>.
For more detail information see below.
