Use the supplied coaxial cable to feed in the LO signal. If no external mixers are con-
nected to the R&S
FSV/A, cover the two front connectors [LO OUT / IF IN] and [IF IN]
with the SMA caps supplied.
1. Connect the LO OUT / IF IN output of the R&S
FSV/A to the LO port of the external
mixer.
2. Connect the IF IN input of the R&S
FSV/A to the IF port of the external mixer.
3. Feed the signal to be measured to the RF input of the external mixer.
To connect a two-port mixer
1. 1. Connect the LO OUT / IF IN output of the R&S
FSV/A to the LO/IF port of the
external mixer. The nominal LO level is 15.5 dBm.
Because of the diplexer contained in the R&S
FSV/A, the IF signal can be tapped
from the line which is used to feed the LO signal to the mixer.
2. Feed the signal to be measured to the RF input of the external mixer.
To activate and configure the external mixer
1. Select "INPUT > Input Source Config > External Mixer: ON" to activate the external
mixer for the current application.
2. Select "Mixer Settings > Band" to define the required frequency range.
3. From the "Band" selection list, select the required band.
4. In the Mixer Settings, select "Conversion Loss: Table" for Range 1 to define fre-
quency-dependent level correction.
5. From the selection list, select a conversion loss table stored on the instrument. No
further settings are necessary since the selected file contains all required parame-
