UNI-T
UTD2000E Series Osilloscope Programming Manual
Set timebase display mode as XY12
（
X-Y mode
：
display amplitude of channel 1 on the horizontal
axis, display amplitude of channel 2 on the vertical axis
）
; YT
（
Y-T mode
：
display the relative
relationship of vertical voltage and horiziontal time
）。
Return format：
Query return XY12, YT.
For example：
:DISP:TYPE YT
set timebase format as YT mode
:DISP:TYPE?
query return YT
WAVeform Command
This command is to read waveform data on the screen and set parameter.
:WAVeform:MODE
Command format：
:WAVeform:MODE
{NORMal | RAW}
:WAVeform:MODE?
Functional description：
NORMal
：
read the display waveform data on the screen, the waveform data points is fixed points.
RAW
：
read the waveform data in memory storage, the waveform data points is related to the
storage depth. Notes: Read the data of memory storage is valid only when oscilloscope stops, this
command is invalid when in MATH channel.
Return format：
query return {NORMal | RAW}.
For example：
:WAVeform:MODE RAW
set the read mode as RAW
:WAVeform:MODE?
query return RAW
:WAVeform:FORMat
Command format：
:WAVeform:FORMat
{ WORD |
BYTE |
ASCII }
:WAVeform:FORMat?
Functional description：
The default format of waveform data is AD waveform point
BYTE
：
return AD data, one waveform point takes one byte
（
8 bits
）
WORD
：
return AD data, one waveform point takes two bytes
（
16 bits
），
low 8 bits is valid, high
8 bits is 0
ASCII
：
return the actual voltage value of each waveform point by scientific notation method,
each voltage value separate by comma mark.
