Running COAX and TWINAX Autotests
The FrameScope 350 and the DualRemote 350 support both
Coaxial and Twinaxial standards. This section will instruct you
how to test to these standards.
COAX Testing
Coaxial cable (also called Coax) consists of an insulated central
conducting wire wrapped in another cylindrical conducting
wire. Both of these wires are encased in an insulating layer and
an outer protective layer. Coax is typically used in carrying
high-speed data and in CATV.
Testing of coaxial cable checks only for length and cable
integrity. Because of this, there is no need to calibrate before
the Autotest. Only a subset of the tester settings applies to Coax
testing. These settings are shown on the screens below.
1 Insert the Coax probe in the FrameScope 350’s SmartProbe port and
connect it to the coaxial cable to be tested. The FrameScope 350 will
automatically detect it and change several settings. There is no need
to use the DualRemote 350 in certifying Coax cables. Press the
Autotest
button on the Main Menu to bring up the Autotest Setup
screen. Press the Edit Settings button to change any settings.

2 When the Coax probe is inserted a default Coax cable is
automatically selected. You can change to a different Coax cable in
the Autotest Settings screen.
