bandwidth of 2 GHz . The IF output can then be analyzed by a different instrument, for
example an R&S
®
RTO oscilloscope.
For instrument model R&S FSW85, the IF output can also be provided at the optional
"IF OUT 2 GHz" output connector at a frequency of 2 GHz and with a bandwidth of
2 GHz . The IF output can then be analyzed by a different instrument. However, con-
sider the note on the 2 GHz / 5 GHz bandwidth extension option below.
If "2ND IF" output is activated, the measured values are no longer available on the dis-
play; thus, the trace data currently displayed on the R&S
FSW becomes invalid. A
message in the status bar indicates this situation. The message also indicates whether
the sidebands of the IF spectrum output are in normal or inverted order compared to
the RF signal, which depends on the used center frequency.
2 GHz / 5 GHz bandwidth extension option (R&S FSW-B2000/B5000)
To analyze IF data with a bandwidth of 2 GHz / 5 GHz using an R&S
®
RTO oscillo-
scope, it is recommended that you use the fully integrated solution including alignment
with the
2 GHz / 5 GHz bandwidth extension option (R&S FSW-B2000/B5000) ,
rather than the "2ND IF" output solution.
If the B2000/B5000 option is activated, the "2ND IF" output is automatically deactiva-
ted. It is not reactivated when the B2000/B5000 option is switched off.
For details see the R&S
FSW I/Q Analyzer and I/Q Input User Manual.
