4 byte, Delta between absolute level and limit line value at corresponding fre-
quency
If no limit line is active, the delta value is set to 0.0
The trace has to be active for the command to work.
Querying the status of the measurement results
The SCPI parameter
STATUS
returns the status information for each measurement
result. Thus, the number of returned values depends on the number of measurement
results
n . For each measurement result, the parameter queries 1 byte of status infor-
mation.
➙
bit 2 represents overrange for trace 1 to trace 6
Note that the
SCAN
parameter only works while the scan is actually running.
Example:
TRAC? STATUS
Querying spectrogram data
The SCPI parameter
SGRam
returns the contents of the spectrogram.
For every frame (horizontal line) in the spectrogram, the command returns the power
levels that have been measured, one for each sweep or measurement point. The num-
ber of frames depends on the size of the history depth. The power level depends on
the unit you have currently set.
TRACe<n>[:DATA]? <ResultType>
This command queries current trace data and measurement results.
The data format depends on
FORMat[:DATA]
.
Reading out trace data in IF analysis is possible with
TRACe<n>:IF[:DATA]
.
Suffix:
<n>
