4. If the results indicate that dependencies between different standards in the signal
may exist:
a) Select the secondary application in which unusual data occurs.
b) If necessary, perform a new data acquisition.
c) Determine the bandwidth or measurement time of the unusual data.
d) Select the MSRA View to compare the data with the other standard secondary
applications.
If a specific event (e.g. a burst, spur etc.) occurs in another standard at the
same time as the unusual data in the first secondary application, the two
effects may be correlated.
e) Select the possibly dependant standard secondary application.
f) Define an analysis interval for the conspicuous data range (as described in
"How to analyze the captured I/Q data in MSRA secondary applications"
g) Refresh the result display for the changed analysis interval ("Sweep" menu).
Now you can analyze the data in detail to determine the cause of the unusual sig-
nal behavior.
How to perform a measurement in the time or frequency domain in MSRA mode
1. Capture I/Q data with the MSRA primary application as described in
2. Activate an "I/Q Analyzer" channel as an MSRA secondary application as descri-
bed in
"How to analyze the captured I/Q data in MSRA secondary applications"
3. In the I/Q Analyzer secondary application, press the [MEAS] key.
4. From the "Select Measurement" dialog box, select the required measurement in
the time or frequency domain.
5. Configure the measurement as described in the R&S
FSWP User Manual.
The I/Q data captured by the MSRA primary application is analyzed in the time or
frequency domain, according to the selected measurement and result displays.
6. To switch back to a conventional I/Q analysis, press the [MEAS] key and select the
"IQ Analyzer" measurement.
