ORBIT FR G-DualScan - Manual (Page 3)

G-DualScan uses a Vector Network Analyzer as the
RF source/receiver for antenna measurements. The
Amplification Unit has RF amplifiers for each of the RX
and TX channels. G-DualScan uses a Transfer Switching
Unit to emit from the AUT to the probe(s) or vice versa.
A dedicated RF switch allows the selection of either the
single-probe or the multi-probe set-up. The Positioner Controller drives the goniometer and azimuth axes for the
AUT, and the elevation axis for the gantry arm. Measure-
ments can be performed in both continuous wave and
optional pulsed mode. In the case of phased array anten-
na measurement, the system utilizes an optional real time
controller to control and synchronize the measurement
system with the device under test.
