5.22 WAVeform Group

The commands in this group deal with the acquired waveform data.
There are no front panel keys that correspond to the commands in this group.
:WAVeform?
Function Queries all waveform display data output settings.
:WAVeform?
Syntax
:WAVeform:BYTeorder
Function Sets or queries the output byte order of the
waveform display data (FLOAT format) that is
transmitted by the :WAVeform:SEND? command.
:WAVeform:BYTeorder {LSBFirst|
Syntax
MSBFirst}
:WAVeform:BYTeorder?
:WAVEFORM:BYTEORDER MSBFIRST
Example
:WAVEFORM:BYTEORDER? ->
:WAVEFORM:BYTEORDER MSBFIRST
Description This command is valid when :WAVeform:FORMat
is set to FLOat.
:WAVeform:END
Function Sets or queries the output end point of the
waveform display data that is transmitted by the :
WAVeform:SEND? command.
:WAVeform:END {<NRf>}
Syntax
:WAVeform:END?
<NRf> = 0 to 1601
:WAVEFORM:END 1601
Example
:WAVEFORM:END? ->
:WAVEFORM:END 1601
:WAVeform:FORMat
Function Sets or queries the format of the waveform
display data that is transmitted by the :WAVeform:
SEND? command.
:WAVeform:FORMat {ASCii|FLOat}
Syntax
:WAVeform:FORMat?
:WAVEFORM:FORMAT FLOAT
Example
:WAVEFORM:FORMAT? ->
:WAVEFORM:FORMAT FLOAT
Description For information about the differences in waveform
display data output between formats, see the
description of the :WAVeform:SEND? command.
5-100
:WAVeform:HOLD
Function Sets or queries the on/off (hold/release) status
of the waveform display data hold feature for all
waveforms.
:WAVeform:HOLD {<Boolean>}
Syntax
:WAVeform:HOLD?
:WAVEFORM:HOLD ON
Example
:WAVEFORM:HOLD? ->
:WAVEFORM:HOLD 1
Description • If :WAVeform:HOLD is set to ON before :
WAVeform:SEND? is executed, all the
waveform data at that point can be held
internally.
• As long as :WAVeform:HOLD is set to
ON, waveform data is held even when the
waveform display on the screen is updated.
• For example, if you want to acquire U1 and
I1 waveform display data at the same point in
time, use the following commands:
:WAVeform:HOLD ON
:WAVeform:TRACe U1
:WAVeform:SEND?
(Receive the waveform display data of U1.)
:WAVeform:TRACe I1
:WAVeform:SEND?
(Receive the waveform display data of I1.)
:WAVeform:HOLD OFF
• If :WAVeform:HOLD is set to ON after having
already been set to ON before, the waveform
display data is cleared, and the most recent
waveform data is held internally.When
retrieving waveform display data continuously,
this method can be used to circumvent the
need to repeatedly set :WAVeform:HOLD to
OFF.
:WAVeform:LENGth?
Function Queries the total number of points of the
waveform specified by the :WAVeform:TRACe
command.
:WAVeform:LENGth?
Syntax
:WAVEFORM:LENGTH? -> 1602
Example
Description The number of data points is fixed.This command
always returns 1602.
