:DISPlay:CLEar
Syntax
:DISPlay:CLEar
Description
Clears all the waveforms on the screen. If the oscilloscope is in the RUN state, after the waveform data is
cleared, new waveform data will be displayed. This command functions the same as the CLEAR key on the
front panel.
:DISPlay:DATA?
Syntax
:DISPlay:DATA?
Description
Reads the bitmap data stream of the currently displayed image on the screen.
Remarks
The command is sent from the PC to the instrument through the VISA interface. The instrument

responds to the command and directly returns the bitmap data stream of the currently displayed
image on the screen to the buffer area of the PC.
Ensure that there is enough buffer space to receive the data stream; otherwise, errors might occur in

reading the program.
To acquire the standard bitmap data, remove the TMC data block header in the returned string.

When the length of the data stream is greater than 1 MByte, you need to set a proper timeout time if

the communication speed of the interface is not fast enough.
You need to remove the end mark (\n(0X0A)) at the end of the data.
