    Safety Precautions Remove Power Observe general safety precautions. Do not open the instrument with the power on. Safety Earth Ground An uninterruptible safety earth ground must be supplied from the main power source to the instrument. Grounding one conductor of a two conductor power cable is not sufficient protection.
  • Page 4 Harsh or abrasive detergents, and some solvents, can damage the display unit and information on the labels. CAUTION When using a Bird 5011, do not exceed 2 W average or 125 W peak power for 5 µs. Doing so will render the sensor inoperative. CAUTION +22 dBm max.

    Chapter 4 Measure Match Mode This measurement verifies and monitors the match conditions in the antenna system at various frequencies. The results are shown on an x-y graph. Frequency is shown on the x-axis while return loss, cable loss, or VSWR is shown on the y-axis. Set the frequency and calibrate the Site Analyzer before taking any readings.

  • Page 28: Setting The Frequency

    Bird Site Analyzer Setting the Frequency Frequencies can be set manually or chosen from a list of presets. If the start, stop, center, or span is manually changed, the band will become “Custom”. NOTE: Changing the frequency settings will automatically turn calibration off. Always set the frequency before calibrating the unit.

    Chapter 5 Fault Location Mode This measurement identifies the position of impedance discontinuities (faults) 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.

  • Page 44: Setting The Frequency Span

    Bird Site Analyzer Setting the Frequency Span The frequency span and relative propagation velocity determine the maximum distance at which distance- to-fault measurements can be taken. For best results, use the table below to select the frequency span which matches the length and either the propagation velocity or dielectric constant of the cable under test.
  • Page 45 Fault Location Mode For example, for a cable with a dielectric constant of 2.778, the velocity percentage is 60%. If the cable is 100 feet long, then the Site Analyzer should be set to a frequency span of 700 MHz. The resolution of the graph will be 5 inches.
