Connect the 'LO OUT / IF IN' output of the R&S FSP 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 FSP the IF signal can be tapped
from the line which is used to feed the LO signal to the mixer.
➢
Feed the signal to be measured to the RF input of the external mixer.
