Distance To Fault
Mode
distance to measured distance times the number of points you have specified. The higher
the number of data points, the greater the measurement resolution.
In most cases, the default resolution using 256 data points will be adequate to locate the
faults, but if more resolution is needed you can increase the span between the start and
stop frequencies (which will decrease the measured distance) or use the other approach,
automatic frequency range. If the measurement distance is not long enough for the cable
you are testing, reduce the span between the start and stop frequencies (which will
increase the measurement distance) or use automatic frequency range.
When testing cables attached to antennas, test signals are radiated from the test antenna
Verify that the signal used for the test, and therefore being radiated from the test antenna,
cannot interfere with other radiated signals from other antennas.
To configure measurement settings, select
Distance to Fault and then press Meas Setup.
Meas Setup
This section describes the keys available with Distance to Fault measurement. To access the
Meas Setup keys used to set up a Distance to Fault measurement. That measurement must
already be selected by pressing
Meas, Distance to Fault.
Avg Mode
Sets the type of termination control used for the averaging function. This determines the
type of averaging used for the specified number of measurements.
Off Turns averaging functions off.
