Description
WAVfrm?
< s trin g >
Query only. Response is a waveform from the oscilloscope, in
the form: WFMpre <ascii string>; CURVe <string>w hich
is a concatenation of the WFMpre and CURVe queries. The
waveform pointed to by the DATa SOUrce and DATa CHAnnel
pointers are sent in the current DATa ENCdg format.
CURVe
<Wfm Data>
The CURVe command or query is used to send or receive
waveform data from the oscilloscope. The DATa SOUrce or
DATa TARget pointers show where to get or put data,
respectively. The DATa ENCdg pointer shows which format,
HEX, BINary, or ASCii data is sent or expected. The DATa
CHAnnel pointer selects either CHI or CH2. <Wfm Data> is
in the form: CURVE <Data>; where <Data> is either
•
%<Byte CountxBinary DataxChecksum > for BINary,
#H<Byte CountxHexadecimal DataxChecksum > for
HEX, or <ASCII Data> for ASCii ENCdg. For ASCii ENCdg,
each data value is seperated by a comma.
DATa
SOUrce
REF1
Sets data parameters for data transmission and reception.
Selects which reference memory is source for the next
REF2
WFMpre? or CURVe? query sent to the instrument. The
REF3
REF4
[ACQ]
default at power-up is ACQuisition.
TARget
REF1
Selects which reference memory receives the next WFMpre or
REF2
CURVe command sent to the instrument. The default at
REF3
REF4
power-up is REFI.
CHAnnel
[CHI]
Points to the waveform that a CURVe? or WAVfrm? query will
CH2
return. If there is no waveform for the CHAnnel and SOUrce
selected (empty reference), an SRQ error is sent when the
waveform is requested. Power-up default is CHI.
ENCdg
ASCii
Sets the data encoding/decoding format. The default at power-
[BINary]
HEX
up is BINary. All ENCdg formats represent an unsigned integer.
