To configure frequency settings at the vector signal generator
Test setups typically require a defined setting of the frequency band configuration
R&S
FE50DTR. Configure this setting in the "RF Frontend" dialog of the
R&S
SMW.
1. To define IF range and internal LO of the R&S
FE50DTR, set the "Frequency
Band Config" mode:
● "IF High": Requires an R&S
SMW equipped with frequency option
R&S
SMW-B1007 or higher.
A higher IF is used on the external frontend. Use this setting, e.g., if your
measurement setup requires high analysis bandwidths (> 400
MHz) at the
R&S
FSV/A.
● "IF Low": A lower IF is used on the external frontend.
The used IF and the used frequency band of the RF input signal are set auto-
matically.
2. Set the reference frequency for the internal LO of the external frontend.
FE50DTR-type frontends can be used by an analyzer and a signal generator
simultaneously. In this case, both channels use the same internal LO and thus
both signal paths operate on the same frequency. Therefore, make sure that
the frequency band configuration is identical on both instruments.

Operating the R&S
FE50DTR in simultaneous
mode
In simultaneous mode, the R&S
FE50DTR operates in Tx mode and Rx mode
simultaneously. The R&S
FE50DTR receives a low-frequency IF signal from the
vector signal generator. It upconverts this signal using its own internal local oscil-
