The used IF and the frequency band of the input signal are set automatically.
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 Tx mode
In Tx mode, the R&S
FE50DTR receives a low-frequency IF signal from the vec-
tor signal generator. It upconverts this signal using its own internal local oscillator
(LO) to a high-frequency RF signal. The R&S
FE50DTR outputs and transmits
this RF signal to the DUT.
