For details, see the R&S FSW I/Q Analyzer and I/Q Input User Manual.
5.2.2.9 IF/VIDEO/DEMOD OUTPUT
The female BNC connector can be used for various outputs:
●
Intermediate frequency (IF) output of approximately 20 MHz
●
Video output (1V)
Which output is provided is defined in the software ([INPUT/OUTPUT] key).
For details, see "Data Output" on page 437.
5.2.2.10 TRIGGER 3 INPUT/ OUTPUT
The additional female BNC "TRIGGER INPUT / OUTPUT" connector can be used to
receive a third external signal or to provide a signal to another device. The signal is
TTL compatible (0 V / 5 V). You can control the connector usage in the "Trigger" set-
tings ([TRIG] key).
5.2.2.11 Digital Baseband Interface (R&S FSW-B17) and R&S EX-IQ-BOX
The R&S FSW Digital Baseband Interface option (R&S FSW-B17) provides an online
digital I/Q data interface on the rear panel of the instrument for input and output. The
digital input and output can be enabled in the base unit or in one of the applications
(where available).
Optionally, an R&S EX-IQ-BOX can be connected to the Digital Baseband Interface to
convert signal properties and the transmission protocol of the R&S
FSW into user-
defined or standardized signal formats and vice versa.
Since the Digital I/Q input and the Analog Baseband input use the same digital signal
path, both cannot be used simultaneously. When one is activated, established connec-
tions for the other are disconnected. When the second input is deactivated, connec-
tions to the first are re-established. This can cause a short delay in data transfer after
switching the input source.
For more information on the Digital Baseband Interface (R&S FSW-B17) and typical
applications, see the R&S FSW I/Q Analyzer User Manual.
5.2.2.12 SYNC TRIGGER OUTPUT/INPUT
Use the SYNC TRIGGER OUTPUT/INPUT connectors to synchronize several devices
(e.g. two R&S
FSWs) to a common trigger signal or reference frequency. The
R&S FSW can output a 100 MHz signal as a trigger or reference signal to another
device. The R&S FSW can also receive an external trigger or reference signal at the
input connector.
