6.23 WAVeform Group

The commands in this group deal with the output of the retrieved waveform display data.
There are no front panel keys that correspond to the commands in this group.
:WAVeform?
Function Queries all settings related to the output of
waveform display data.
Syntax :WAVeform?
Example :WAVEFORM? -> :WAVEFORM:TRACE U1;
FORMAT ASCII;START 0;END 1001;
HOLD 0
:WAVeform:BYTeorder
Function Sets the output byte order of the waveform
display data (FLOAT format) that is transmitted
by ":WAVeform:SEND?" or queries the current
setting.
Syntax :WAVeform:BYTeorder {LSBFirst|
MSBFirst}
:WAVeform:BYTeorder?
Example :WAVEFORM:BYTEORDER LSBFIRST
:WAVEFORM:BYTEORDER? ->
:WAVEFORM:BYTEORDER LSBFIRST
Description This value is valid when ":WAVeform:FORMat"
is set to "{FLOat}."
:WAVeform:END
Function Sets the output end point of the waveform
display data that is transmitted by
":WAVeform:SEND?" or queries the current
setting.
Syntax :WAVeform:END {<NRf>}
:WAVeform:END?
<NRf> = 0 to 1001
Example :WAVEFORM:END 1001
:WAVEFORM:END? ->
:WAVEFORM:END 1001
:WAVeform:FORMat
Function Sets the format of the waveform display data
that is transmitted by ":WAVeform:SEND?" or
queries the current setting.
Syntax :WAVeform:FORMat {ASCii|FLOat}
:WAVeform:FORMat?
Example :WAVEFORM:FORMAT FLOAT
:WAVEFORM:FORMAT? ->
:WAVEFORM:FORMAT FLOAT
Description For the differences in the waveform display data
output due to the format setting, see the
description for ":WAVeform:SEND?."
6-112
:WAVeform:HOLD
Function Sets whether to hold (ON) or release (OFF) all
the waveform display data or queries the current
setting.
Syntax :WAVeform:HOLD {<Boolean>}
:WAVeform:HOLD?
Example :WAVEFORM:HOLD ON
:WAVEFORM:HOLD? -> :WAVEFORM:HOLD 1
Description • If :WAVeform:HOLD is turned ON before
executing ":WAVeform:SEND?," all the
waveform data at that point can be held
internally.
• As long as :WAVeform:HOLD is ON, the
waveform data is held even when the
waveform display on the screen is updated.
• For example, if you wish to retrieve the
waveform display data of U1 and I1 at the
same point, do the following:
: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 ON is specified when :WAVeform:HOLD is
ON, the waveform display data is cleared
once, and the most recent waveform data is
held internally. This method can be used
when retrieving waveform display data
continuously (no need to set
:WAVeform:HOLD to OFF each time).
:WAVeform:LENGth?
Function Queries the total number of points of the
waveform specified by :WAVeform:TRACe.
Syntax :WAVeform:LENGth?
Example :WAVEFORM:LENGTH? -> 1002
Description The number of data points is fixed. "1002" is
always returned.
