SENSe1
).
CALC:FORM MLIN; :FORM ASCII; FORM:DEXP:SOUR FDAT
Select the trace data format: linear magnitude values, ASCII format and formatted
trace data (1 value per sweep point).
TRAC? CH1DATA
Query the 20 response values of the created trace according to the previous
format settings.
The following parameters are related to trace data (see also
Data Flow
diagram):
CH<nr>Data
Response values of the data trace for channels 1 to 4. The data is transferred in the data format defined via
FORMat[:DATA] and
FORMat:DEXPort:SOURce
.
MDATa<nr>
Response values for the memory trace named "Mem<nr>...]. The data is transferred in the data format defined
via FORMat[:DATA] and
FORMat:DEXPort:SOURce
.
CH<nr>Mem,
MDATa
Response values of the memory trace for channels 1 to 4 (8). The data is transferred in the data format defined
via FORMat[:DATA] and
FORMat:DEXPort:SOURce
.
CH<nr>Fdata,
CH<nr>FMEM
Formatted trace data, according to the selected trace format (
CALCulate<Chn>:FORMat
). 1 value per trace
point for Cartesian diagrams, 2 values for polar diagrams.
CH<nr>Sdata,
CH<nr>SMEM
Unformatted trace data: Real and imaginary part of each measurement point. 2 values per trace point
irrespective of the selected trace format. The trace mathematics is not taken into account.

CH1Mem | CH2Mem | CH3Mem | CH4Mem | MDATa1 | MDATa2 | MDATa3 | MDATa4
| MDATa5 | MDATa6 | MDATa7 | MDATa8
Returns the stimulus values of the active data trace or memory trace (see trace names).
To read the stimulus values of an arbitrary data or memory trace, use
CALCulate<Chn>:DATA:STIMulus?
<Response>
Response data of the selected trace, see list of trace names.
Range [def. unit]
The data is transferred in the data format defined via FORMat[:DATA]. The
numeric values are expressed in the default unit of the stimulus variable. [Hz,
dBm or s, depending on the sweep type]

Types
Device-specific, query only
Example:
SWE:POIN 20
Create a trace with 20 sweep points, making the created trace the active trace of
channel 1 (omitted optional mnemonic
SENSe1
).
TRAC:STIM? CH1DATA
Query the 20 stimulus values of the created trace. In the default format setting,
the data is returned as a comma-separated list of 10-digit ASCII values.
