:WAVeform:SEND?
Function Queries the waveform data specified with the
“
WAVeform:TRACe ” command.
Syntax :WAVeform:SEND? [{<NRf>}]
<NRf>= 1 to 1024 (DL1720E)
1 to 2048 (DL1740E/DL1740EL)
(depends on the record length setting)
Example :WAVEFORM:SEND? -> #8 (number of
bytes, 8 digits)(data string) or,
<NRf>,<NRf>, ....
Description The output format of “ WAVeform:SEND? ”
varies depending on the “ WAVeform:FORMat ”
setting.
(1)When set to “ASCii”
• When the “ WAVeform:TRACe ” is 1 to 8
and the linear scaling is OFF, the values
are returned in the following format:
<voltage>, <voltage>, ...<voltage>
• When the “ WAVeform:TRACe ” is a logic
input, the values are returned in the
following format:
<NR1>, <NR1>, ..., <NR1>
<NR1> is an 8-bit pattern (bit 7 to 0) that
has been made into a decimal.
• For all other cases, the values are
returned in the form: <NRf>, <NRf>, ...,
<NRf>.
(2)When set to “BYTE” or “WORD”
The values are returned in the <block data>
format.
• When the “
WAVeform:TRACe ” is not set
to a logic input, the following equation can
be used to convert the values.
Voltage (computed value) =
(Range
×
data
÷
division*) + offset
* “BYTE”: Division = 12
“WORD”: Division = 3072
Query is not possible if
“
WAVeform:TRACe ” set to MATH1 or
MATH2 and the computation is turned
OFF.
• <NRf> can be omitted. If <NRf> is added,
waveform data are queried <NRf> times
from the record number specified by the
“
:WAVeform:RECord ” command - <NRf>
in order.
:WAVeform:SIGN?
Function Queries the presence of the sign, when
querying the waveform specified with
“
WAVeform:TRACe ” in binary data form.
Syntax :WAVeform:SIGN?
Example :WAVEFORM:SIGN? -> :WAVEFORM:SIGN 1
:WAVeform:SRATe? (Sample RATE)
Function Queries the sampling rate for the record
designated by “
WAVeform:RECord ”.
Syntax :WAVeform:SRATe?
Example :WAVEFORM:SRATE? ->
:WAVEFORM:SRATE 1.0E+09
:WAVeform:STARt
Function Sets/queries the point at which the first item of
data of the waveform designated by
“
WAVeform:TRACe ” is to be located.
Syntax :WAVeform:STARt {<NRf>}
:WAVeform:STARt?
<NRf>= 0 to 1001999 (DL1720E)
0 to 2003999 (DL1740E)
0 to 8015999 (DL1740EL)
Example :WAVEFORM:START 0
:WAVEFORM:START? ->
:WAVEFORM:START 0
:WAVeform:TRACe
Function Sets/queries the target waveform for the
WAVeform group.
Syntax :WAVeform:TRACe {<NRf>|MATH<x>}
:WAVeform:TRACe?
<x>=1 or 2 (1 on the DL1720E)
<NRf>=1 to 4 (1 to 2 on the DL1720E)
Example :WAVEFORM:TRACE 1
:WAVEFORM:TRACE? ->
:WAVEFORM:TRACE 1
:WAVeform:TRIGger?
Function Queries the trigger point for the record
designated by “
WAVeform:RECord ”.
Syntax :WAVeform:TRIGger?
Example :WAVEFORM:TRIGGER? ->
:WAVEFORM:TRIGGER 2000
Description Returns the number of points between the
record start and the trigger position.
:WAVeform:TYPE?
Function Queries the acquisition mode for the waveform
specified by the “
WAVeform:TRACe ” command.
Syntax :WAVeform:TYPE?
Example :WAVEFORM:TYPE? ->
:WAVEFORM:TYPE NORMAL
