Setting Up Copper Tests
Copper and VDSL2/ADSL2+ Multi-play Test Set 63
Application Settings
Application Settings
Before executing the copper tests, set up the software settings and values
for the cables. The MAX-635 allows you to save standard parameter settings
to different profiles and reuse them as needed.
To access Application Settings:
From the Home pane, select Copper Test, then Setup, and
Application Settings.
The following parameters are available to configure:
General
The General tab allows you to configure the unit with
specific measurement values and graph viewing
settings.
Each parameter is described below:

Cable Temperature specifies the temperature of
the cable under test in either F (Fahrenheit) or C
(Celsius) units.

Capacitance Measurement is either 3 Terminal
or 2 Terminal. The latter method measures the
capacitance across the 2 terminals specified
(either T-R, T-G, R-G or A-B, A-E, B-E), whereas the
3 Terminal method measures the capacitance across the 2 terminals
specified, and shorts the remaining (or unspecified) terminal to G/E.
Note: In order to correctly determine cable length by using the Capacitance
Measurement, the Cable Book must contain both 3/2 Terminal values.
Note: The accuracy of the 2 Terminal Capacitance Measurement is impacted by
the use of the FED, and the 3 Terminal method is recommended to be used
instead.
