R&S FSH3 Setting the Amplitude Parameters
This mode is useful if you want to display, for example, a carrier being amplitude modulated in the time
domain (SPAN = 0 Hz).
The R&S FSH3 can also handle measurements on 75 Ω systems. The R&S FSH3 does not select a
75 Ω RF input per se, but instead only a 75 Ω matching pad connected at the RF input. The
50/75 Ω Matching Pad R&S RAZ is recommended for 75 Ω matching (see recommended accessories).
The R&S FSH3 automatically considers the conversion factor when a value of 75 Ω is set. Other
matching pads such as the R&S RAM can be taken into account by using a transducer factor.
