:WAVeform:DATA?
Syntax
:WAVeform:DATA?
Description
Read the waveform data.
Explanation
Procedures of the screen waveform data reading:
1) Set the channel: :WAV:SOURce CHAN1
2) Select NORMal mode: :WAV:MODE NORM
3) Read the screen waveform data: :WAV:DATA?
2) Select NORMal mode: :WAV:MODE NORM
3) Read the screen waveform data: :WAV:DATA?
Procedures of the internal memory waveform data reading:
1) Set to STOP state: :STOP
2) Set the channel: :WAV:SOURce CHAN1
3) Select RAW mode: :WAV:MODE RAW
4) Read the waveform data in the internal memory: :WAV:DATA?
2) Set the channel: :WAV:SOURce CHAN1
3) Select RAW mode: :WAV:MODE RAW
4) Read the waveform data in the internal memory: :WAV:DATA?
Return
Format
The data returned contains 2 parts: the TMC data description header and the
waveform data. The format of the TMC data description header is #900000dddd
followed which is the waveform data. Wherein, dddd
denotes the number of the
effective waveform points in the data stream. For example, as shown in the figure
below, #9000015865 is the TMC data description header. Wherein, 15865 denotes
that 15 865 bytes effective data will be followed. The waveform data is closely
followed. The return format here is ASCii.
),
the query returns the actual voltage of each points on the screen in scientific
notation.
When reading the waveform in the internal memory, the data returned each time
may be part of the data in the internal memory (can be set by
and
). Each part of the data returned has the TMC data description
header and the waveform data from two adjacent parts are continuous.
