Agilent Technologies 8935 series e6380a Cable Fault, Locations by viewing it in units of distance

Overview of the Test Set’s Built-In Tools

Using the RF Tools Program

	Cable Fault
	Measurement Description
	A frequency-swept signal is transmitted from the DUPLEX OUT port of
	the Test Set through a resistive power divider to the cable-under-test.
	The signals reflected from faults in the cable are combined in the power
	divider with the transmitted signal and received at the ANT IN port.
	The changing interference of the transmitted and reflected signals, over
	the swept frequency band, contains information about the distance to
	one or more faults. The software uses a Fast Fourier Transform (FFT)
	to convert the frequency domain into the time domain. The information
	in the time domain can be used to find the physical distances. The
	distance displayed on the Test Set’s CRT is the physical distance to the
	fault with correction for the velocity factor of the cable. This test allows
	the operator to identify, characterize, and isolate potential problem
	locations by viewing it in units of distance.
	Test Signal Can Cause Interference
NOTE
	When testing cables attached to antennas, test signals will be radiated.
	Verify that the signal used for the test cannot result in interference to
	another antenna.
