Cable Fault Location

Cable Fault Location
To access the keys for setting up a cable fault location measurement, press
MEASURE
Used to specify the number of data acquisitions that will be averaged. After the
Avg Number
specified number of average counts, the averaging mode (terminal control) setting
determines the averaging action.
On
Off
Default values are 10 and Off, and range values are 1 to 1000.
Used to select the type of termination control used for the averaging function. This
Avg Mode
determines the averaging action after the specified number of data acquisitions
(average count) is reached.
Exponential
Repeat
The default value is exponential.
Used to calibrate the spectrum analyzer, removing any errors introduced by the
Calibrate
cabling and components of the test setup before making the measurement.
Cable Type Used to select the type of cable being tested. Provides access to the Cable Editor
form, displaying a table listing relevant cable types, plus the following keys:
Cable
Vel Factor
Cable Loss/m
Store Table
Start Distance Used to define the start position of the range over which faults will be measured.
This allows the user to zoom in on certain faults.
The default value is 0 m.

Cable Fault Location
Sets measurement averaging on.
Sets measurement averaging off.
After the average count is reached, each successive data
acquisition is exponentially weighted and combined with the
existing average.
After reaching the average count, the averaging is reset and a
new average is started.
Used to select an entry in the cable type table. Accepts numeric
values.
The velocity factor for the cable type selected. The field's
numeric value represents a proportion of the speed of light. The
value can be edited and saved using the
The amount of signal lost per meter for the cable type selected,
expressed in dB. The value can be edited and saved using the
Store Table key.
Used to save any changes made to the
