The WAVeform group deals with acquired waveform data.
:WAVeform?
Function Queries all settings related to waveform data.
:WAVeform?
Syntax
:WAVeform:ACOunt?
Function Queries the acquisition count.
:WAVeform:ACOunt?
Syntax
:WAVEFORM:ACOUNT? -> :WAVEFORM:
Example
ACOUNT 10
Description The function returns the acquired acquisition count.
The function returns "0" when data has not been
acquired at least once.
:WAVeform:BITS?
Function Queries the bit length of the waveform data specified
by ":WAVeform:TRACe".
:WAVeform:BITS?
Syntax
:WAVEFORM:BITS? -> :WAVEFORM:BITS 16
Example
Description The bit length which is output with this command is
not the same as 'the valid bit length of A/D'. For the
SL1000, all analog Ch will be '16'.
:WAVeform:BYTeorder
Function Sets or queries the byte order when using word
format of two bytes or more.
:WAVeform:BYTeorder {LSBFirst|MSBFirst}
Syntax
:WAVeform:BYTeorder?
:WAVEFORM:BYTEORDER LSBFIRST
Example
:WAVEFORM:BYTEORDER? -> :WAVEFORM:
BYTEORDER LSBFIRST
Description This command is valid for only the commands of the
WAVEfrom group.
3-64
:WAVeform:DIVision?
Function Queries the Division value used when converting the
waveform data specified by 'WAVeform:TRACe' to
physical values.
:WAVeform:DIVision?
Syntax
:WAVEFORM:DIVISION? -> :WAVEFORM:
Example
DIVISION 24.000000E+03
Description The data is output per the current 'WAVeform:
FORMat' setting of the specified trace. The Division
value varies according to the kind of input module as
follows.

:WAVeform:END
Function Sets or queries the final data point of the waveform
(main waveform) specified by 'WAVeform:TRACe'.
:WAVeform:END {<NRf>}
Syntax
:WAVeform:END?
<NRf>=0 to (total number of data points-1)
:WAVEFORM:END 100000
Example
:WAVEFORM:END? -> :WAVEFORM:END 100000
Description The total number of data points can be queried using
:WAVeform:CAPTure:LENGth?
:WAVeform:FORMat
