WAVEFORM TRANSFER - WAVEFORM, WF

Description

The WAVEFORM command transfers a waveform from the controller to the oscilloscope. The

WAVEFORM? query reads a waveform from the oscilloscope to the controller.

WAVEFORM stores an external waveform back into the oscilloscope's internal memory. A

waveform consists of several distinct entities:

 DESC - The descriptor

 TEXT - The user text

 TIME - The time descriptor

 DAT1 - The data block

and, optionally...

 DAT2 - A second block of data

NOTE: Only complete waveforms queried with WAVEFORM? ALL can be restored to the

oscilloscope.

The WAVEFORM? query instructs the oscilloscope to transmit a waveform to the controller. The

entities can be queried independently. When the ALL parameter is specified, all four or five

entities are transmitted in one block in the order listed above.

NOTE: The format of the waveform data depends on the current settings specified by

the last WAVEFORM_SETUP command.

Command Syntax

<memory>:WaveForm ALL,<data_block>

<memory>:= {M1,M2,M3,M4,M5,M6,M7,M8,M9,M10}

<data_block>:= waveform data block.

Query Syntax

<trace>:WaveForm? <entity>

<trace>:= {TA,TB,TC,TD,C1,C2,C3,C4,M1,M2,M3,M4,M5,M6,M7,M8,M9,M10}

<entity>:= {DESC, TEXT, TIME, DAT1, DAT2, ALL}

If you do not provide a parameter, ALL is assumed.
