Communication Commands
: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)(data byte sequence)
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.
• If there is no waveform display data even when
the display mode (
:DISPlay:MODE
) is set to a
mode to display waveforms, the data is output
as follows:
(1) When “
ASCii
” is specified
The data of all points are output as “NAN.”
(2) When “
FLOat
” is specified
The data of all points are output as
“0(0x00000000).”
: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> = 0 to 1001
Example
:WAVEFORM:START 0
:WAVEFORM:START? ->
:WAVEFORM:START 0
:WAVeform:TRACe
Function
Sets the target waveform for “:WAVeform:SEND?”
or queries the current setting.
Syntax
:WAVeform:TRACe {U<x>|I<x>|SPEed|
TORQue|MATH<x>}
:WAVeform:TRACe?
<x> of U<x>, I<x> = 1 to 4 (element)
<x> of MATH<x> = 1 to 2 (MATH)
Example
:WAVEFORM:TRACE U1
:WAVEFORM:TRACE? ->
:WAVEFORM:TRACE U1
Description
{SPEed|TORQue}
are valid only on models with
the motor evaluation function (/MTR option).
: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.
