Commands of the TRACe subsystem
TRACe<n>[:DATA]?
<ResultType>
This command returns the current trace data or measurement results. In case of sev-
eral result displays, you have to use specific parameters to query the results.
For details on saving and recalling data refer to the
MMEMory
subsystem in the
description of the base unit.
Suffix:
<n>
.
1...4
window; For applications that have only one measurement
screen, the suffix is irrelevant.
Query parameters:
<ResultType>
TRACE1 | TRACE2 | TRACE3 | TRACE4 | TRACE5 | TRACE6
Selects the type of result to be returned.
TRACE1 | ...| TRACE6
The query returns a list of results with one value for each sweep
point in the currently set level unit.
For details see
Example:
TRAC? TRACE1
Returns the trace data for Trace 1.
Usage:
Query only
Mode:
A, ADEMOD, BT, NF, PHN, TDS
Table 2-4: Results for <TRACe...> ResultTypes
The query returns a list of results with one value for each sweep point in the currently set level unit. By
default, the list contains 691 values. The currently used number of sweep points can be determined using
SWE:POIN?, see
FORMat REAL,32
is used as format for binary transmission, and
FORMat ASCii
for ASCII transmission.
With the auto peak detector, only positive peak values can be read out.
In
IQ Analyzer mode
, if the result display configuration "Real/Imag (I/Q)" is selected, this query returns the
I values of each trace point first, then the Q values:
<result>= I
1
,I
