Waveform Commands
The Waveform subsystem is used to transfer waveform data between a
computer and the digitizer. It contains commands to set up the waveform
transfer and to receive waveform records from the digitizer.
:WAVeform:BYTeorder
Command
:WAVeform:BYTeorder {MSBFirst | LSBFirst}
Description The command selects the order in which bytes are transferred from the
digitizer using WORD format.
MSBFirst
The most significant byte is transferred first.
LSBFirst
The least significant byte is transferred first (default).
Query
:WAVeform:BYTeorder?
The query returns the current setting for the byte order.
Returned Format
[:WAVeform:BYTeorder] {MSBFirst | LSBFirst}<NL>
:WAVeform:DATA?
Query
:WAVeform:DATA? CHANnel<N>, <start>,<size>
Description The query outputs waveform data to the computer over the remote
interface. The data is copied from a channel given by the first parameter.
The waveform data is ASCII formatted. The data consists of waveform data
values converted to volts and is formatted as a string of ASCII characters
with each value separated from the next value by a comma. The values are
formatted in floating point engineering notation. For example:
8.0836E+2,8.1090E+2,...,-3.1245E-3
If
DPRocessing
is set to
DIRect
, 10-bit ADC samples in signed 16-bit
integer representation are transferred. If set to
DDC
, 16-bit I and 16-bit Q
samples interleaved in signed 16-bit integer representation are
transferred.
<N> An integer, 1-4.
<start>
An integer value which is the starting point in the source
memory which is the first waveform point to transfer.
