other connected devices. Using the same trigger on several devices is useful to syn-
chronize the transmitted and received signals within a measurement.
For details on the connectors see the R&S FSW "Getting Started" manual.
External trigger as input
If the trigger signal for the R&S FSW is provided by an external device, the trigger sig-
nal source must be connected to the R&S FSW and the trigger source must be defined
as "External" in the R&S FSW.
External triggers with R&S FSW-B2000
When the input is provided from an R&S FSW with the B2000 option, the connected
oscilloscope samples the data. Thus, triggering is also processed by the oscilloscope.
The trigger source can be either the IF level or an external trigger, for example from
the R&S FSW.
In this case, the trigger source must be defined as "External CH3" in the R&S FSW.
Trigger output
The R&S FSW can provide output to another device either to pass on the internal trig-
ger signal, or to indicate that the R&S FSW itself is ready to trigger.
The trigger signal can be output by the R&S FSW automatically, or manually by the
user. If it is provided automatically, a high signal is output when the R&S FSW has trig-
gered due to a sweep start ("Device Triggered"), or when the R&S FSW is ready to
receive a trigger signal after a sweep start ("Trigger Armed").
Manual triggering
If the trigger output signal is initiated manually, the length and level (high/low) of the
trigger pulse is also user-definable. Note, however, that the trigger pulse level is
always opposite to the constant signal level defined by the output "Level" setting, e.g.
for "Level = High", a constant high signal is output to the connector until the "Send
Trigger" button is selected. Then, a low pulse is provided.

Mode
The Analog Demodulation application can also be used to analyze data in MSRA or
MSRT operating mode. The main difference between the two modes is that in MSRA
