5.20 WAVeform Group
: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?
• When ":WAVeform:FORMat" is set to {ASCii}
Example
: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-byte) 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 sampling 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).
5-84
: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>|SPEed|
TORQue}
:WAVeform:TRACe?
<x> = 1 to 6 (element)
Example :WAVEFORM:TRACE U1
:WAVEFORM:TRACE? -> :WAVEFORM:
TRACE U1
Description {SPEed|TORQue} is valid only when the motor
evaluation function (/MTR option) is installed.
: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.
