3.3 Antenna Test
AV3680A can test the return loss/VSWR of general passive receiving antenna. This part will introduce
the measurement process of passive antenna by taking terminal antennaTZD-P021Z05-195 as an example.
Terminal antenna TZD-P021Z05-195 is kind of receiving antenna with frequency of 2,100MHz, whose
standing wave is minimum at 2,100MHz in theory.
1. Press
【
MEAS
】
to choose “Return Loss” or “VSWR” as the measurement format of Tester.
2. Press
【
FREQ/DIST
】
to set instrument frequency measurement range by contrasting with receiving
frequency range of the antenna to be received; if the frequency range of antenna is not clear, users can
measure return loss/VSWR according to system default measurement range (1MHz~4MHz), which is
set to2GHz ~ 2.2GHz here.
3. As the antenna has interface with diameter of 3.5mm, N-3.5mm adapter needs to be connected to the
test port of Tester, and then use the calibration kit (option) with diameter of 3.5mm to calibrate the Tester
as described in section 3.1.
4. After calibration, connect the measured antenna to Tester as shown in Figure 3.22.
