Quick Start Guide for AV3680A Handled Cable & Antenna Tester
Make corresponding adjustment on the displayed amplitude according to amplitude set-method described
in section 3.5; then press
【
Marker
】
to turn on the marker function, so that you can see the VSWR
situation of antenna at each frequency. Through observation we can find that VSWR of antenna is smaller
near 2,100MHz, with minimum at 2,104MHz.

3.4 Universal Devices and Parts Test
Addition to cable and antenna test, AV3680A can also be used for testing the attenuation, cable
connectors, cable joints, etc. This part will measure the return loss of 10dB attenuation, as an example,
with operations as follows:
1. Press
【
MEAS
】
to choose “Return Loss” as the measurement format of Tester.
2. Press
【
FREQ/DIST
】
to set measurement range of Tester according to the working frequency range
of attenuator; if the frequency range of attenuator is not clear, users can measure the return loss/ VSWR
according to the system default frequency range (1MHz ~ 4GHz).
3. As the attenuator to be measured 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 attenuator to Tester and the match load to the terminal of
attenuator as shown in Figure 3.24.
