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

automatically selected. You can change to a different Coax cable in<br />
the Autotest Settings screen.<br />

network operation over Coax. By selecting Other in the Network<br />
