(b) Setup for Analog TX measurement
In the Analog TX measurement, the MT8801C sends the AF signal to the
DUT for modulating the transmission signal of the DUT, and receives the
transmission signal. Then, modulates the signal to measure the modulation
degree.
There are 2 methods for sending the AF signal to the DUT for modulation.
(i) Sending AF signal with AF Output connector (front panel)
(ii) Sending AF signal with DUT Interface connector (front panel)
Setup is described depending on these methods, below.
(i) Setup using AF Output connector (at front panel)
