DISP
Syntax DISP {DATA|MEMO|DATM|DMNM|DELP|DDVM}
DISP?
Description For the active trace (set with the “TRAC” command on page 457), makes the setting
related to the displayed trace.
If a parameter other than DATM is set, the scale setting target trace (set with the “SCAF”
command on page 422) and the marker use target trace (set with the “MKRO” command
on page 356) are also changed.
If no data has been copied to the memory trace (the “DATMEM” command on page 285
has not been executed), executing this command to set a parameter other than DATA
causes an error and the command is ignored.
If the measurement parameter is a scalar value, executing this command to set DDVM
causes an error and the command is ignored. If the measurement parameter is a vector
value, executing this command to set DELP causes an error and the command is ignored.

Description
*1
DATA
(initial value)
Displays the data trace. The contents of the data trace is measured
data (no operation).
MEMO
*2 Displays the memory trace.
DATM
*2 Displays both the data trace and the memory trace at the same time.
The contents of the data trace is measured data (no operation).
DMNM
*2 Displays the data trace. The contents of the data trace is the
operation result of DATA - MEM.
DELP
*2,*3 Displays the data trace. The contents of the data trace is the
operation result of (DATA - MEM) / MEM.
DDVM
*2,*4 Displays the data trace. The contents of the data trace is the
operation result of DATA / MEM.
*1.In operation expressions in the description, DATA indicates measured
data and MEM indicates data of the memory trace.
*2.Selectable only when data has been copied in the memory trace.
*3.Selectable only when the measurement parameter is a scalar value.
*4.Selectable only when the measurement parameter is a vector value.
