: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?
.”
: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.
:WAVeform:SEND?
Function Queries the waveform display data specified by
“ :WAVeform:TRACe ”.
Syntax :WAVeform:SEND?
Example • When “ :WAVeform:FORMat ” is set to
{ASCii}
:WAVEFORM:SEND? -> <NR3>,<NR3>,
...
• When “ :WAVeform:FORMat ” is set to
{FLOat}
:WAVEFORM:SEND? -> #4 (number of
bytes, 4 digits) (series of data bytes)
Description The format of the waveform display data that is
output varies depending on the
“ :WAVeform:FORMat ” setting as follows.
(1)When “ASCii” is specified
The physical value is output in the <NR3>
format.The data of each point is delimited by
a comma.
(2)When “FLOat” is specified
The physical value is output in IEEE single-
precision floating point (4-bytes) format.
The output byte order of the data of each
point follows the order that is set using the
“ :WAVeform:BYTeorder ” command.
:WAVeform:SRATe?
Function Queries the sample rate of the retrieved
waveform.
Syntax :WAVeform:SRATe?
Example :WAVEFORM:SRATE? -> 200.000E+03
:WAVeform:STARt
Function Sets the output start point of the waveform
display data that is transmitted by
“:WAVeform:SEND?” or queries the current
setting.
Syntax :WAVeform:STARt {<NRf>}
:WAVeform:STARt?
<NRf>
to 0 to (total number of data points - 1)
Example :WAVEFORM:START 0
:WAVEFORM:START? -> :WAVEFORM:
START 0
Description The “
:WAVeform:LENGth?
” command can be
used to query the (total number of data points).
:WAVeform:TRACe
Function Sets the target waveform for the
WAVeform:
SEND
and
WAVeform:LENGth
commands or
queries the current setting.
Syntax :WAVeform:TRACe {U<x>|I<x>}
:WAVeform:TRACe?
<x> = 1 to 4 (power measurement element)
Example :WAVEFORM:TRACE U1
:WAVEFORM:TRACE? -> :WAVEFORM:
TRACE U1
:WAVeform:TRIGger?
Function Queries the trigger position of the retrieved
waveform.
Syntax :WAVeform:TRIGger?
Example :WAVEFORM:TRIGGER? -> 0
Description Since the trigger position is always at the
beginning of the waveform display data, “0” is
returned.
