Chapter 4 Fault Location Mode Fault location identifies the position of impedance discontinuities (reflections) within the antenna/feeder system. The measurement results are displayed on an x-y graph. Distance from the Site Analyzer is shown on the x-axis, while relative magnitude of the discontinuity is shown on the y-axis.
Bird Technologies Note: Changing the frequency settings will automatically turn calibration off. Always set the frequency before calibrating the unit. Note: If you enter a frequency that is outside of the range of the Site Analyzer, the Site Analyzer will override your entry and set the minimum or maximum frequency of the model. Select Fault Location Mode 1. Apply power to the Site Analyzer.
Fault Location Mode What You Need to Know About Setting the Frequency Span and Max Distance Note: Changing the frequency span or the max distance will automatically turn calibration off. Always set the frequency span or max distance before calibrating the unit. The maximum distance you can measure is determined by the frequency span, the velocity of propagation of the cable (Vp), and the number of data points to measure (238, 475, or 949). These factors are discussed in the following paragraphs.
Bird Technologies Setting the Frequency Span For a given number of data points (238, 475, 949), entering a frequency span causes the Site Analyzer to calculate and enter the maximum measurable distance and, conversely, entering a maximum distance causes the Site Analyzer to calculate and enter the required frequency span. There are two methods you can use to determine the frequency span (for both methods, you need to know the maximum distance, velocity of propagation, and number of data points).
Fault Location Mode 3. Enter the frequency span. Follow the numbered steps in Figure 20 on page 51 to enter the values you determined in Step 2. 4. Enter the center frequency. The center frequency is the center of the antenna’s frequency range. To set the max distance, follow the numbered steps in Figure 20 on page 51.
Bird Technologies Setting the Maximum Distance Note: Changing the frequency span or the max distance will automatically turn calibration off. Always set the frequency span or max distance before calibrating the unit. 1. Select the Fault Location mode (Figure 19 on page 48). 2. Follow the numbered steps in Figure 21 on page 52 to enter the maximum distance value. 3. At the warning message (Figure 22, page 53) press Enter to accept your entry or Esc to cancel your entry.
Fault Location Mode Figure 22 Changed Max Distance Warning Message Calibrate the Site Analyzer If you need to use an extension cable or a phase stable cable, connect that cable to the antenna test port on the Site Analyzer and then connect the Bird Calibration Combination to the end of the extension cable. Follow the procedure in Chapter 2, Calibration, page 15. Note: After calibration, with the load still connected, the output must be below –45 dB. If it is not, there is a problem.
Bird Technologies 1. Make sure that Fault Location mode is selected (refer to Select Fault Location Mode, page 48). 2. To manually set the cable type, follow the numbered steps in Figure 23. To select the cable type from a predefined list, follow the steps in Figure 24.

Bird Technologies Test for Fault Location 1. Connect the Site Analyzer to the cable being tested. Note: If you calibrated the Site Analyzer with a phase stable cable connected to its antenna port, do not remove the cable. Connect it to the cable to be tested. 2. Wait at least 10 seconds for the sweep to update.
Fault Location Mode 1. Each connector or jumper will show up as a spike. If it is larger than the typical value, check the connector for damage. 2. Spikes where there are no components represent faults. Note the distance and check the line at that point for damage. 3. The largest spike is usually due to the antenna. Typically the trace after the antenna can be ignored. 4.
Bird Technologies Markers You must be in either Measure Match mode or Fault Location mode to use markers. You can activate and use up to six markers to visually indicate the trace value at specific frequency points. All markers follow the current trace only. The site analyzer displays the frequency and signal value for each marker at the bottom of the screen. You can display each marker as a triangle pointer or a vertical line through the trace.

Bird Technologies Using Delta Markers In the delta marker mode, only active markers will be visible. The delta marker feature displays the difference (delta) in both frequency and value between the selected marker and each active marker. If the limit line is active, you will also see the difference between the selected marker and the limit line. The frequency difference between the selected marker and the limit line will always be the frequency of the marker. All markers follow the current trace only.
Fault Location Mode Using Markers with Recalled Traces When a trace is recalled, the screen displays both the current trace and the recalled trace and there is an additional marker option, single / dual mode. In single mode, the markers function normally; the site analyzer displays the frequency and trace magnitude at each marker. In dual mode, the markers show the actual magnitude of both traces and the difference in magnitude between the recalled trace and the current reading.
Bird Technologies Smooth Smooth is an option that will digitally average the displayed trace. There are three levels of smoothing, low medium, and high. Follow the steps in Figure 38 to set smoothing. Figure 39, page 76 shows the same trace with high smoothing selected.
Fault Location Mode Saving The Measurement You can save the trace and recall and review it at a later time (refer to Save Trace, page 80). Printing The Bird Site Analyzer can print the information displayed on the screen to any HP Deskjet printer that supports the PCL Level 3 protocol. To print the screen image, first hold the image (Figure 33, page 69) then press the Print softkey (Figure 40, item 1).

Chapter 6 Measure Power Mode Note: The figures in this chapter do not show the entire Site Analyzer. The figures show only the screen image and the keys you press to accomplish a setup or measurement. Note: Power measurement comes standard on all models except the SA-1700EX. To upgrade a SA-1700EX to a SA6000EX, which has power measurement capability, please contact Customer Service. This measurement verifies and monitors the condition of the transmitter system.
Bird Technologies Figure 56 Connecting the SA to Measure Power Connecting a Sensor CAUTION Always turn off the SA before connecting or disconnecting a sensor. Although unlikely, it is possible to corrupt the power sensor firmware by connecting it to the Site Analyzer while the SA is on. To prevent this, turn the SA off before connecting or disconnecting a sensor. Use a 9-pin serial cable to connect a power sensor to the Site Analyzer’s serial port, labeled “Remote Power Sensor” (Figure 56 on page 100).
Measure Power Mode CAUTION +22 dBm max. input Do not apply RF power to Antenna Test Port. Exceeding the maximum input will damage the Site Analyzer. The antenna test port is used only for testing unpowered systems. For power measurement, you must connect an external power sensor to the “Remote Power Sensor” port (see Figure 56 on page 100). CAUTION When using a Bird 5011 or 5011-EF, do not exceed 2 W average or 125 W peak power for 5 µs. Doing so will render the sensor inoperative.
Bird Technologies Display Description Figure 57 Measure Power Screen Features 1 Measure Power Sample Display, with a sensor properly connected 2 3 4 5 6 7 Item Description Explanation 1 Sensor Status Indicates the connection status of the power sensor. 2 Primary Measurement Identifies the measurement displayed on the analog dial. 3 Primary Value Numeric display of the primary value. 4 Measurement Scale Indicates the dial’s full scale.
Measure Power Mode Setting the Full Scale Power For element-based sensors, enter the power rating listed on the forward element before making any measurements. Also, check that the reflected element’s rating is 10% of the forward element’s. Press from Measure Power Mode Scroll to Full Scale Enter the forward element power The Bird Site Analyzer will automatically set the full scale power for sensors that do not use elements, such as the Bird 5011 or 5012.
Bird Technologies Zeroing Bird Power Sensors CAUTION When using a Bird 5011 or 5011-EF, do not exceed 2 W average or 125 W peak power for 5 µs. Doing so will render the sensor inoperative. Over time, the sensor’s “zero value” (reading with no applied RF power) can drift, making all readings inaccurate by this value. For example, if the zero value is –2 µW, measuring a 5 mW signal will give a reading of 4.998 mW, a 0.04% error. Periodically re-zero the sensor. This applies to 5011 and 5012 power sensors.
Measure Power Mode Press to accept the warning Wait for calibration to finish 105
Bird Technologies Choosing the Displayed Measurement The primary display shows one value on the large numerical display and the pointer. Other measurements are displayed numerically below the dial. Note: When using a terminating power sensor, only forward power can be measured. Reflected power and match will not be displayed.
Measure Power Mode Changing the mode for the 5010B The 5010B has three modes of operation, APM, 43Avg, and 43Peak. Bird 43 Elements can measure average, peak, and average of max. and min. power. Bird APM Elements only measure average power. The 43Peak Mode When the 5010B is in the 43Peak mode, the measurements change as shown below. Note: When using the 5010B in the 43Peak mode, the match units are no longer needed and are greyed out.
Bird Technologies Using the 5012 Wideband Power Sensor Changing the Measurement Type The 5012 has three different measurement modes, Create, Burst, and CCDF. Choosing the Displayed Measurement There are five measurements that can be displayed in each measurement type. FWD, REFL and MATCH are common to all of the measurement types. The other two depend on the measurement type as show in the table below. Meas. Type Displayed Meas.
Measure Power Mode Function Descriptions Average Power Average power is a measure of the equivalent “heating” power of a signal, as measured with a calorimeter. It measures the total RF power in the system, and does not depend on number of carriers or modulation scheme. The WPS is a broadband sensor that measures power across its entire frequency range.
Bird Technologies Video Filter Except for average power and VSWR measurements, all WPS measurements rely on a variable video filter to improve accuracy. This filter can be set to either 4.5 kHz, 400 kHz, or full bandwidth. It should be as narrow as possible while still being larger than the demodulated signal bandwidth (video bandwidth). Narrowing the filter limits the noise contribution caused by interfering signals. Listed below are some common modulation schemes and the appropriate video filter.
Measure Power Mode Peak Envelope Power Peak power measurements detect amplitude changes as a signal modulates the carrier envelope. The WPS operates in an asynchronous cycle: 300 ms of waveform sampling followed by a 50 ms reset period. The peak power is then displayed and the cycle repeats. The display therefore updates about three times per second. Burst Average Power Burst width (BW) is the duration of a pulse. Period (P) is the time from the start of one pulse to the start of the next pulse.
Bird Technologies Crest Factor Crest factor (CF) is the ratio of the peak and average powers, in dB. The WPS calculates the Crest Factor from the Forward Peak and Average Power measurements. Crest Factor 10 dB CDMA Signal 100 W Peak 10 W Ave 100 W Peak Envelope Power 50 W Average Power 0W Complementary Cumulative Distribution Function (CCDF) CCDF measures the amount of time the power is above a threshold. Equivalently, it is the probability that any single measurement will be above the threshold.
Measure Power Mode Setting the CCDF Limit Press from Measure Power Mode Scroll to CCDF Lim Enter the new value The CCDF Limit is displayed at the bottom of the main display 113
Bird Technologies Setting the Offset To read unattenuated power when using a coupler or attenuator, enter (in dB) the attenuation or coupling factor. To convert percentages to dB, use the equation: Attenuation (dB) = 10 x Log10 [Attenuation (%) / 100] 5011-EF The Bird 5011-EF uses frequency-dependent correction factors to provide more accurate measurements. To use these, look at the label on the side of the sensor and find the correction factor at the frequency being measured.
Measure Power Mode The offset is displayed at the bottom of the main display 115
Bird Technologies Recall Setups Power measurement setups can be created using the Bird Site Analyzer PCTool Software, then stored in the Site Analyzer’s nonvolatile memory. These setups store both the offset and the full scale power.
