2.1.4 Transmission Measurements (R&S ZVH-K39)
You can equip the R&S ZVH with option R&S ZVH-K39 (order no 1309.6830.02) to
enable forward transmission measurements (S21).
With the forward transmission measurement you can test if a radio signal can travel
through the line without losses. The transmission measurement helps to find faults by
displaying the magnitude of the reflections in dB in a specified frequency range.
Typically you perform transmission measurements on a filter to test if it works alright or
test the isolation of two antennas (e.g. two receiving antennas or a receiving and a
transmitting antenna).
► Press the MEAS key.
► Press the "Transmission (S21)"
softkey.
The R&S ZVH starts the forward
transmission measurement over
its entire frequency range.
The figure shows the results of a
transmission measurement on a filter.
The results show that the filter works
as it's supposed to.
