ACQuisition Group

The commands in this group deal with output of the waveform sampling data (acquisition data).
There are no front panel keys that correspond to the commands in this group.
The commands in this group are valid only when the advanced computation function (/G6 option) is installed.
:ACQuisition?
Function Queries all settings related to the output of the
waveform sampling data.
Syntax :ACQuisition?
Example :ACQUISITION? -> :ACQUISITION:
TRACE U1;FORMAT ASCII;START 0;
END 199999;HOLD 0
:ACQuisition:BYTeorder
Function Sets the output byte order of the waveform
sampling data (FLOAT format) that is
transmitted by ":ACQuisition:SEND?" or
queries the current setting.
Syntax :ACQuisition:BYTeorder {LSBFirst|
MSBFirst}
:ACQuisition:BYTeorder?
Example :ACQUISITION:BYTEORDER LSBFIRST
:ACQUISITION:BYTEORDER? ->
:ACQUISITION:BYTEORDER LSBFIRST
Description This value is valid when
":ACQuisition:FORMat" is set to FLOat.
:ACQuisition:END
Function Sets the output end point of the waveform
display data that is transmitted by
":ACQuisition:SEND?" or queries the current
setting.
Syntax :ACQuisition:END {<NRf>}
:ACQuisition:END?
<NRf> = 0 to 3999999
Example :ACQUISITION:END 199999
:ACQUISITION:END? ->
:ACQUISITION:END 199999
Description Set the point in the range up to (the total
number of data points – 1). The total number of
data points can be queried using
":ACQuisition:LENGth?."
IM 760301-17E
:ACQuisition:FORMat
Function Sets the format of the waveform sampling data
that is transmitted by ":ACQuisition:SEND?"
or queries the current setting.
Syntax :ACQuisition:FORMat {ASCii|FLOat}
:ACQuisition:FORMat?
Example :ACQUISITION:FORMAT FLOAT
:ACQUISITION:FORMAT? ->
:ACQUISITION:FORMAT FLOAT
Description For the differences in the waveform sampling
data output due to the format setting, see the
description for ":ACQuisition:SEND?."
:ACQuisition:HOLD
Function Sets whether to hold (ON) or release (OFF) all
the waveform sampling data or queries the
current setting.
Syntax :ACQuisition:HOLD {<Boolean>}
:ACQuisition:HOLD?
Example :ACQUISITION:HOLD ON
:ACQUISITION:HOLD? ->
:ACQUISITION:HOLD 1
Description • This command is valid when the
measurement mode is set to MATH or FFT.
Otherwise, an error occurs.
• When ":ACQuisition:HOLD" is turned ON,
the WT3000 stops sampling the waveform
sampling data and holds all of the waveform
sampling data at that point internally. Be sure
to set :ACQuisition:HOLD to ON before
executing ":ACQuisition:SEND?."
• For example, if you wish to retrieve the
waveform sampling data of U1 and I1 at the
same point, do the following:
:ACQuisition:HOLD ON
:ACQuisition:TRACe U1
:ACQuisition:SEND?
(Receive the waveform sampling data of U1)
:ACQuisition:TRACe I1
:ACQuisition:SEND?
(Receive the waveform sampling data of I1)
:ACQuisition:HOLD OFF
• To retrieve new waveform sampling data, set
:ACQuisition:HOLD to OFF to resume
sampling, and then set
:ACQuisition:HOLD to ON again.
