For measurement on DUTs that need an external voltage supply (e.g. power
amplifiers), you can connect the supply voltage from a suitable AC power supply to
the BIAS Port 1 or use the internal bias.
By default, the R&S FSH is in spectrum analyzer mode after you have turned it on. To
switch to the DTF mode from another operating mode, proceed as follows.
M
Press the MODE key.
M
Press the "Distance-to-Fault" softkey.
The R&S FSH starts the DTF mode.
