RF Immunity High / Low
The instrument defaults to RF Immunity High. This setting protects the instrument from
stray signals from nearby or co-located transmitters that can affect frequency and DTF
measurements. The algorithm used to improve instrument’s ability to reject unwanted
signals slows down the sweep speed. If the instrument is used in an environment where
immunity is not as issue, the RF Immunity key can be set to Low to optimize sweep speed.
Use this feature with caution, as the introduction of an interfering signal might be mistaken
for a problem with the antenna or cable run. If Immunity is set to Low during a normal RL
or VSWR measurement, the instrument will be more susceptible to interfering signals.
Interfering signals can make the measurement look better or worse than it really is.
1. Press the Sweep/Setup main menu key.
2. Toggle the RF Immunity High/Low key.
Data Points
The number of data points can be set to 137, 275, 551, 1102, and 2204 data points. This can be
changed before or after calibration regardless of the display setting. The default setting is
275. This is recommended for most measurements. More data points slow down the sweep
speed. More data points are helpful in DTF as this enables better coverage for the same fault
resolution.
1. Press the Sweep/Setup main menu key.
2. Select 137, 275, 551, 1102, or 2204 data points.
Refer to “Sweep/Setup Menu” on page 2-32 for additional information about the Sweep/Setup
main menu and submenus.
Averaging
Averaging helps to average out the trace and minimize the effect of outliers. Trace averaging
takes the running average of the number of traces indicated in the Averaging Factor. The
Average Count in the status window turns on if Averaging is turned on. When the Average
Count reaches the entered average count, a running average of the last set of sweeps is
performed. Averaging Factor can be set between 1 and 65535.
1. Press the Sweep/Setup main menu key.
2. Press the Averaging/Smoothing submenu key.
3. Press Averaging Factor and enter the number of running averages using the keypad,
then press the Enter key.
4. Press the Averaging On/Off key and toggle Averaging to On.
5. Use the Restart key to start the averaging sequence from the beginning.

Smoothing %
Smoothing is a mathematical function that calculates a rolling average of the trace data.
This provides a way to look at the general shape of a measurement while smoothing out
smaller variations. The value is the amount of the display that is incorporated into the rolling
average. Valid entries range from 0% (no smoothing) to 10% (maximum smoothing).
The display in Figure 2-1 illustrates how smoothing can be used to reduce ripples when
making 1-port cable loss measurements. The white trace shows the trace with no smoothing
and the yellow trace shows the trace with 7% smoothing.
1. Press the Sweep/Setup main menu key.
2. Press the Averaging/Smoothing submenu key.
3. Select the Smoothing % key and enter the level of smoothing (1% to 10%).
Figure 2-1.
Smoothing Reduces Ripple
Output Power (Low/High)
The power level defaults to High for all 1-port measurements (~ 0 dBm). It can be changed to
Low (~ –35 dBm) if needed. All line sweep 1-port measurements should be performed with the
output power High setting.
1. Press the Sweep/Setup main menu key.
2. Select the Output Power submenu key and toggle Output Power between High and Low.

Cable and Antenna Measurements Overview

Cable and Antenna Measurements Overview
Line Sweep Fundamentals
In wireless communication, the transmit and receive antennas are connected to the radio
through a transmission line. This transmission line is usually a coaxial cable or waveguide.
This connection system is referred to as a transmission feed line system. Figure 2-10 shows
an example of a typical transmission feed line system.
Figure 2-10. A Typical Transmission Feedline System
The performance of a transmission feed line system may be affected by excessive signal
reflection and cable loss. Signal reflection occurs when the RF signal reflects back due to an
impedance mismatch or change in impedance caused by excessive kinking or bending of the
transmission line. Cable loss is caused by attenuation of the signal as it passes through the
transmission line and connectors. To verify the performance of the transmission feed line
system and analyze these problems, three types of line sweeps are required:
• Return Loss
• Cable Loss, and
• Distance-To-Fault.
The measurements for these sweeps are defined as
• Return Loss - System Sweep,
• DTF - Load Sweep, and
• Cable Loss Sweep.

Cable and Antenna Measurements Overview
Line Sweep Types
Return Loss / VSWR Measurement
Return Loss measures the reflected power of the system in decibels (dB). This measurement
can also be taken in the Standing Wave Ratio (SWR) mode, which is the ratio of the
transmitted power to the reflected power.
Cable Loss Measurement
Measures the energy absorbed, or lost, by the transmission line in dB/meter or dB/ft.
Different transmission lines have different losses, and the loss is frequency and distance
specific. The higher the frequency or longer the distance, the greater the loss.
Distance-To-Fault (DTF) Measurement
Reveals the precise fault location of components in the transmission line system. This test
helps to identify specific problems in the system, such as connector transitions, jumpers,
kinks in the cable or moisture intrusion.
Line Sweep Measurement Types
Return Loss – System Sweep
A measurement made when the antenna is connected at the end of the transmission line. This
measurement provides an analysis of how the various components of the system are
interacting and provides an aggregate return loss of the entire system.
Distance To Fault – Load Sweep
A measurement is made with the antenna disconnected and replaced with a 50Ω precision
load at the end of the transmission line. This measurement allows analysis of the various
components of the transmission feed line system in the DTF mode.
Cable Loss Sweep
A measurement made when a short is connected at the end of the transmission line. This
condition allows analysis of the signal loss through the transmission line and identifies the
problems in the system. High insertion loss in the feed line or jumpers can contribute to poor
system performance and loss of coverage.
This whole process of measurements and testing the transmission line system is called Line
Sweeping.

Distance-To-Fault (DTF)
DTF reveals the precise fault location of components in the transmission line system. This
test helps to identify specific problems in the system, such as connector transitions, jumpers,
kinks in the cable or moisture intrusion.
To measure the distance of a cable, DTF measurements can be made with an open or a short
connected at the end of the cable. The peak indicating the end of the cable should be between
0 dB and 5 dB. An open or short should not be used when DTF is used for troubleshooting
because the open/short will reflect everything and the true value of a connector might be
misinterpreted and a good connector could look like a failing connector.
A 50 Ω load is the best termination for troubleshooting DTF problems because it will be 50 Ω
over the entire frequency range. The antenna can also be used as a terminating device but the
impedance of the antenna will change over different frequencies because the antenna is only
designed to have 15 dB or better return loss in the passband of the antenna.
DTF measurement is a frequency domain measurement and the data is transformed to the
time domain using mathematics. The distance information is obtained by analyzing how
much the phase is changing when the system is swept in the frequency domain. Frequency
selective devices such as TMAs (Tower Mounted Amplifiers), duplexers, filters, and quarter
wave lightning arrestors change the phase information (distance information) if they are not
swept over the correct frequencies. Care needs to be taken when setting up the frequency
range whenever a TMA is present in the path.
Because of the nature of the measurement, maximum distance range and fault resolution is
dependent upon the frequency range and number of data points. DTF Aid shows how the
parameters are related. If the cable is longer than DMax, the only way to improve the
horizontal range is to reduce the frequency span or to increase the number of data points.
Similarly, the fault resolution is inversely proportional to the frequency range and the only
way to improve the fault resolution is to widen the frequency span.
The instrument is equipped with a cable list (Figure 2-13) including most of the common
cables used today. Once the correct cable has been selected, the instrument will update the
propagation velocity and the cable attenuation values to correspond with the cable. These
values can also be entered manually. Custom Cable lists can also be created with Master
Software Tools and Uploaded into the instrument. Incorrect propagation velocity values affect
the distance accuracy and inaccurate cable attenuation values affect the accuracy of the
magnitude value.

Fault Resolution
Fault resolution is the system's ability to separate two closely spaced discontinuities. If the
fault resolution is 10 feet and there are two faults 5 feet apart, the instrument will not be able
to show both faults unless Fault Resolution is improved by widening the frequency span.
Fault Resolution (m) = 1.5 x 108 x vp / ΔF
DMax
DMax is the maximum horizontal distance that can be analyzed. The Stop Distance can not
exceed Dmax. If the cable is longer than Dmax, Dmax needs to be improved by increasing the
number of data points or lowering the frequency span (ΔF). Note that the data points can be
set to 137, 275, 551, 1102, or 2204
Dmax = (Datapoints – 1) x Fault Resolution

Example 1 – DTF Transmission Line Test
The Distance-To-Fault transmission line test verifies the performance of the transmission
line assembly and its components and identifies the fault locations in the transmission line
system. This test determines the return loss value of each connector pair, cable component
and cable to identify the problem location. This test can be performed in the DTF-Return Loss
or DTF-VSWR mode. Typically, for field applications, the DTF-Return Loss mode is used. To
perform this test, disconnect the antenna and connect the load at the end of the transmission
line.

Limit lines can be used for visual reference only, or for pass/fail criteria using the limit alarm.
Limit alarm failures are reported whenever a signal crosses the limit line.
Each limit line can consist of a single segment, or as many as 40 segments across the entire
frequency span of the instrument. These limit segments are retained regardless of the current
frequency span of the instrument, allowing the configuring of specific limit envelopes at
various frequencies of interest without having to re-configure them each time the frequency is
changed. To clear the current limit setup configuration and return to a single limit segment
starting at the current start frequency and ending at the current stop frequency, press the
Clear Limit submenu key.
Key Sequence: Shift > Limit (5) key

Point Frequency: The frequency of each point in a limit line can be individually
set. When a new point is added, it takes on a value halfway between two
existing points, or the stop frequency of the current sweep if there is no point
higher in frequency than the one being added. See the Add Point submenu key
description for more details. Use the keypad, the Left/Right arrow keys, or the
rotary knob to change the frequency of a point.
Point Value: The amplitude of each limit point can also be individually set. By
default, when a new point is added, it takes on the amplitude that is on the limit
line at the frequency where the point was added. Use the keypad, using the
± key as the minus sign, the Up/Down arrow keys or the rotary knob to move
the point to the desired value. The unit of the amplitude limit is the same as the
current vertical amplitude unit. See the Add Point submenu key description for
more details.
Add Point: The precise behavior of this submenu key depends on which limit
point is active at the time the key is pressed. If the active limit point is
somewhere in the middle of a multi-segment limit line, a new limit point will be
added that is halfway between the currently active point and the point
immediately to its right. The amplitude of the point will be such that it falls on the
limit line. For example, if there is a limit point at 2.0 GHz with an amplitude of
–30 dBm and the next point is 3.0 GHz with an amplitude of –50 dBm, the
added point will be at 2.5 GHz with an amplitude of –40 dBm. The frequency
and amplitude values of the new point can be adjusted as needed with the
Frequency and Amplitude submenu keys. If the last limit point is active
(assuming it is not at the right edge of the display) the new limit point will be
placed at the right edge of the display at the same amplitude as the point
immediately to its left. Points may not be added beyond the current sweep limits
of the instrument.
Delete Point: This submenu key deletes the currently active point. The active
point becomes the one immediately to the left of the point that was deleted.
Next Point Left: This submenu key selects the limit point immediately to the left
of the active point, making it active for editing or deletion. With each key press,
the indicator of which point is active moves one limit point to the left until it
reaches the left edge of the screen.
Next Point Right: This submenu key selects the limit point immediately to the
right of the active point, making it active for editing or deletion. With each key
press, the indicator of which point is active moves one limit point to the right until
it reaches the right edge of the screen.
Move Limit: This submenu key allows an entire single or multi-segment limit
line to be moved up or down by the number of dB entered using the keypad, the
Up/Down arrow keys, or the rotary knob. The units for this amount will be the
current display units as selected under the Amplitude menu.

Introduction
This chapter provides details and procedures about the following calibration methods:
InstaCal, Open-Short-Load, Standard Cal, Flexcal
3-2
Chapter Overview
• Section 3-3 “Calibration Methods” on page 3-1
• Section 3-4 “Calibration Verification” on page 3-2
• Section 3-5 “Calibration Procedures” on page 3-3
• Section 3-6 “InstaCal Module Verification” on page 3-5
3-3
Calibration Methods
For accurate results, the instrument must be calibrated before making any measurements.
The instrument must be re-calibrated whenever the temperature exceeds the calibration
temperature range or when the test port extension cable is removed or replaced. Unless the
calibration type is Flexcal, the instrument must also be re-calibrated every time the setup
frequency changes.
The instrument can be manually calibrated with a precision OSL (Open-Short-Load)
calibration tee / discrete components or with the InstaCal module. The benefit of the InstaCal
module is that it is much faster, requires no connection changes, and eliminates the need to
use three different terminations (open, short, load) for calibration. The trade-off is that the
specified corrected directivity is 38 dB instead of 42 dB.
While InstaCal or OSL Cal tee provides two alternatives for the tools needed to perform the
calibration, Standard Cal or FlexCal determines how often calibration will need to be
performed. A standard calibration is an Open, Short and Load calibration for a selected
frequency range, and is no longer valid if the frequency is changed. The default calibration
mode is standard.
FlexCal is a broadband frequency calibration that remains valid if the frequency is changed.
Flexcal calibrates the instrument over the entire frequency range and interpolates datapoints
if the frequency range is changed. This method saves time as it does not require the user to
re-calibrate the system for frequency changes. The trade-off is that the accuracy is not the
same as it would be with the standard calibration. It is recommended for troubleshooting
purposes. Table 3-1 has a summary of calibration methods and tools.

Calibration Verification
During the calibration process in Return Loss mode (Measurements > Return Loss), either
with discrete calibration components or with the InstaCal module, there are typical
measurement levels expected. Verifying the measurement levels displayed on the screen
during calibration can save valuable time in the field.
Trace Characteristics in Return Loss Mode
As the individual calibration components are connected to the RF out port, the following
measurement levels will be displayed on the screen:
• When an OPEN is connected, a trace will be displayed between 0 dB to 10 dB.
• When a SHORT is connected, a trace will be displayed between 0 dB to 10 dB.
• When a LOAD is connected, a trace will be displayed between 0 dB to 50 dB.

Calibration Procedures
Calibration Procedures
In Cable and Antenna Analyzer Mode, calibration is required when the “Not Calibrated”
message is displayed or when the test port cable has been changed. The following sections
detail how to perform OSL and InstaCal calibration.
If a Test Port Extension Cable is to be used, it must be connected to the
Site Master before calibration. Follow the same calibration procedures with
the OSL components or the InstaCal module in place at the end of the test port
extension cable.

InstaCal Module Verification
InstaCal Module Verification
Verifying the InstaCal module before any line sweeping measurements is critical to the
measured data. InstaCal module verification identifies any failures in the module due to
circuitry damage or failure of the control circuitry. This test does not attempt to characterize
the InstaCal module, which is performed at the factory or the service center.
The performance of the InstaCal module can be verified by the Termination method which is
similar to testing a bad load against a known good load.
Termination Method
The Termination method compares a precision load against the InstaCal module and provides
a baseline for other field measurements. A precision load provides better than 42 dB
directivity.
1. Set the instrument frequency for the device under test.
2. Press the Measurements main menu key and select Return Loss.
3. Connect the InstaCal module to the instrument’s RF Out port and calibrate the
Site Master using the InstaCal module requiring verification.
4. Remove the InstaCal module from the RF Out port and connect the precision load to the
RF Out port.
5. Measure the return loss of the precision load. The level should be less than 35 dB across
the calibrated frequency range.
6. Press the Marker main menu key and set Marker1 to Marker To Peak. The M1 value
should be less than 35 dB return loss.

Appendix A — Windowing
A-1
Introduction
The theoretical requirement for inverse FFT is for the data to extend from zero frequency to
infinity. Side lobes appear around a discontinuity because the spectrum is cut off at a finite
frequency. Windowing reduces the side lobes by smoothing out the sharp transitions at the
beginning and the end of the frequency sweep. As the side lobes are reduced, the main lobe
widens, thereby reducing the resolution.
In situations where a small discontinuity may be close to a large one, side lobe reduction
windowing helps to reveal the discrete discontinuities. If distance resolution is critical, then
reduce the windowing for greater signal resolution.
If strong interfering frequency components are present, but are distant from the frequency of
interest, then use a windowing format with higher side lobes, such as Rectangular Windowing
or Nominal Side Lobe Windowing.
If strong interfering signals are present and are near the frequency of interest, then use a
windowing format with lower side lobes, such as Low Side Lobe Windowing or Minimum Side
Lobe Windowing.
If two or more signals are very near to each other, then spectral resolution is important. In
this case, use Rectangular Windowing for the sharpest main lobe (the best resolution).
If the amplitude accuracy of a single frequency component is more important than the exact
location of the component in a given frequency bin, then choose a windowing format with a
wide main lobe.
When examining a single frequency, if the amplitude accuracy is more important than the
exact frequency, then use Low Side Lobe Windowing or Minimum Side Lobe Windowing.
