Source Switcher

The source switcher is used to switch test ports to which the RF signal is
supplied from the source.

Signal Separator

The signal separator consists of directivity couplers that detect input and
output signals at the test ports. On a test port to which a signal is output,
the output signal and the reflection from the DUT are detected as the
reference signal (R) and the test signal (T), respectively. On the other
ports, the signal that is transmitted through the DUT is detected as the
test signal (T). All signals are then sent to the receiver.

Receiver

Each signal that is sent to the receiver is first converted into an IF signal
by a mixer and then converted into a digital signal by an ADC (analog to
digital converter). These processes are applied to each signal
independently. The digital data is then analyzed by a micro processor and
measurement results will be displayed on the screen.
