The video output is a signal of 1 V. It can be used, for example, to control demodula-
ted audio frequencies.
The IF output is a signal of the measured level at a specified frequency.
The "2ND IF" output is a signal with a bandwidth of 2 GHz at the frequency 2 GHz.
This output is only available if the "IF OUT 2 GHz/ IF OUT 5 GHz" output connector is
installed. (The availability of this connector depends on the instrument model.)
If the optional 2 GHz / 5 GHz bandwidth extension (R&S FSW-B2000/B5000) is active,
the "IF OUT 2 GHz/ IF OUT 5 GHz" output connector is used to transfer the measured
data from the R&S FSW to the connected oscilloscope. In this case, the "2ND IF" out-
put is automatically deactivated. It is not reactivated when the B2000/B5000 option is
switched off.
The frequency at which the active B5000 option transmits data to the oscilloscope via
the "IF 5 GHz OUT" connector depends on the analysis bandwidth.
Restrictions
Note the following restrictions for data output:
●
IF and video output is only available in the time domain (zero span).
●
For I/Q data, only IF output is available.
●
IF output is not available if any of the following conditions apply:
– The optional Digital Baseband Interface is active (for input or output)
– MSRA operating mode is active
– MSRT operating mode is active
– A wideband extension is used (hardware options R&S FSWB160--B512; used
automatically for bandwidths > 80 MHz; in this case select the "IF WIDE OUT"
output, which uses the "IF WIDE OUTPUT" connector; for bandwidths larger
than 512 MHz, IF output is not available.)
A wideband extension is used (hardware options R&S FSWB160--B512; used
automatically for bandwidths > 80 MHz; in this case select the "IF WIDE OUT"
output, which uses the "IF WIDE OUTPUT" connector)
– The sample rate is larger than 200 MHz (upsampling)
IF WIDE OUTPUT
For bandwidths > 80 MHz, but less than 512 MHz, the IF output is provided at the "IF
WIDE OUTPUT" connector.
For bandwidths larger than 512 MHz, IF output is not available.
In this case, the IF output frequency cannot be defined manually, but is determined
automatically depending on the center frequency. The currently used output frequency
is indicated in the "IF Wide Out Frequency" field of the "Output" dialog box. For details
on the used frequencies see the data sheet.
2ND IF Output
For instrument models R&S FSW26/43/50/67/85, 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
Data Input and Output
