Page 11: Fault Location Measurement Theory
Introduction and Measurement Theory Fault Location Measurement Theory Fault Location Measurement Theory This section describes basic fault location measurement theory, how the analyzer converts frequency-domain data to distance-domain data, and the relationship between start distance, stop distance and frequency span. Fault location measurements are designed to quickly and easily locate faults, or discontinuities, in either 50 ohm or 75 ohm transmission lines.
Page 12 Introduction and Measurement Theory Fault Location Measurement Theory Typically, fault location measurement results are expressed in one of four ways: Format Description Return Loss The number of dB that the reflected signal is below the (RL) incident signal. Its relationship to the reflection coefficient (ρ) is described by the following formula: RL = −20 log ρ.
Page 13: How The Analyzer Converts Frequency Data To Distance Data
Introduction and Measurement Theory Fault Location Measurement Theory How the Analyzer Converts Frequency Data to Distance Data Fault-location measurements are single-ended measurements, meaning that only one end of a cable under test need be connected to the analyzer's RF OUT test port. This type of measurement is generally called a reflection measurement and typically displays a response commonly known as return loss.
Page 14: Start/Stop Distance And Frequency Span Explanation
Introduction and Measurement Theory Fault Location Measurement Theory Start/Stop Distance and Frequency Span Explanation When the analyzer is set up for a fault location measurement, you can determine the center frequency (when in band pass mode), and start and stop distances for the measurement.
Page 15: Cable Impedance And Structural Return Loss Measurement Theory
Introduction and Measurement Theory Cable Impedance and Structural Return Loss Measurement Theory Cable Impedance and Structural Return Loss Measurement Theory The SRL feature is designed to measure cable impedance and structural return loss. Cable impedance is the ratio of voltage to current of a signal traveling in one direction down the cable.
Page 16 Introduction and Measurement Theory Cable Impedance and Structural Return Loss Measurement Theory Equation 1 ( ) Z ω – cable ω ------------------------------------ - ω cable is the impedance seen at the input of the cable, and Z is the nominal cable cable impedance.
Page 17 Introduction and Measurement Theory Cable Impedance and Structural Return Loss Measurement Theory Method 1. One definition of cable impedance is that impedance which results in minimum measured values for SRL reflections over the frequency of interest. This is equivalent to measuring a cable with a return loss bridge that can vary its reference impedance.

Page 19: Srl And Periodic Cable Faults
Introduction and Measurement Theory Cable Impedance and Structural Return Loss Measurement Theory SRL and Periodic Cable Faults SRL is the measure of the reflection of incident energy that is caused by imperfections or disturbances (bumps) in the cable which are distributed throughout the cable length.
Page 20 Introduction and Measurement Theory Cable Impedance and Structural Return Loss Measurement Theory Figure 1-2 diagrams reflections from bumps in a cable. We can combine the energy reflected by each bump in a cable and make a few basic assumptions, to mathematically describe SRL by the series shown in Equation 9.
Page 21 Introduction and Measurement Theory Cable Impedance and Structural Return Loss Measurement Theory The series may be reduced to a simple form to leave us with the relationship shown in Equation 10. The term L is a function of the loss of the cable at a specific frequency and the wavelength at that frequency.
Page 22 Introduction and Measurement Theory Cable Impedance and Structural Return Loss Measurement Theory Derivation of L. In Equation 10, L is the cable loss for a 1/2 wavelength length of cable, expressed in linear. 1. Find the cable loss from a spec sheet. Cable loss is typically expressed in loss per foot.

Introduction and Measurement Theory Cable Impedance and Structural Return Loss Measurement Theory SRL and Discrete Cable Faults In addition to a set of periodic bumps, a cable can also contain one or more discrete faults. For this discussion, discrete imperfections will be referred to as “faults,” and periodic imperfections will be referred to as “bumps.”...
Page 24 Introduction and Measurement Theory Cable Impedance and Structural Return Loss Measurement Theory When measuring spools of cable, typically two connectors are used: the test-lead connector and the termination connector. (See Figure 1-3.) These connectors provide the cable interface and are measured as part of the cable data.

If the termination is shown as a fault, the reflection from the terminating connector is contributing to the reflection from the cable. A more suitable termination is required or a longer section of cable must be measured. The cable must provide sufficient attenuation to remove the effects of the connector and load for a good SRL measurement.

Page 30: Cable Preparation
Cable Preparation Cable preparation (for slip-on connectors) can be critical for some SRL measurements, especially when measuring mainline cables with an SRL of −30 dB or lower. An improperly prepared cable can degrade the cable/connector response which may affect the measurement enough to make a “good” cable fail.

Page 79 Characterizing and Verifying Antenna Systems Antenna Feedline System Evaluating the quality of the components within the antenna feedline system is of utmost importance in today's communication systems. For example, the attenuation of the transmission lines, along with the insertion loss of the combiner, determines the majority of loss that occurs in the transmitting portion of the antenna system.
Page 80: Potential Problems
Characterizing and Verifying Antenna Systems Potential Problems Potential Problems Antenna feedline systems are typically the most common sources of failure in a communication system. The problems associated with these systems can be hard to identify and, once found, are usually located high on a tower. With the right test equipment, identifying and isolating problems becomes very easy, and can be done at ground level.
Page 81 Characterizing and Verifying Antenna Systems Potential Problems Connectors present a great potential for problems, since moisture will invariably find its way inside. Normal atmospheric pressure changes will always equalize unless the system is deliberately pressurized.
