    Chapter 1 General Information InstaCal Module The Anritsu InstaCal module can be used in place of discrete components to calibrate the Site Master. The InstaCal module can be used to perform an Open, Short and Load (OSL) calibration procedure. Calibration of the Site Master with the InstaCal takes approximately 45 seconds (see Calibration, page 3-2).

  • Page 76: Site Master Spectrum Analyzer Features

    Chapter 5 Spectrum Analyzer Measurements Site Master Spectrum Analyzer Features AM/FM Modulation Modulation is the process of translating some low frequency or baseband signal (voice, mu- sic, or data) to a higher frequency. In the modulation process, some characteristic of a car- rier signal (usually amplitude or frequency) is changed in direct proportion to the instantaneous amplitude of the baseband signal.

  • Page 77: Frequency Modulation

    Chapter 5 Spectrum Analyzer Measurements The markers read the frequency difference between the two signals, which is equal to the modulating frequency. The marker also reads the difference in amplitude. This difference in amplitude between the two signals can be used to determine the percentage of modula- tion.

  • Page 90: Measurement Applications

    Chapter 5 Spectrum Analyzer Measurements Measurement Applications Resolving Closely Spaced Signals Signal resolution is determined by the intermediate frequency (IF) filter bandwidth. The hand held spectrum analyzer, as do conventional spectrum analyzers, traces the shape of its IF filter as it tunes past a signal. Thus, if two equal-amplitude signals are close enough in frequency, the filter shapes for the two signals can fall on top of one another and appear as a single response.
  • Page 91 Chapter 5 Spectrum Analyzer Measurements Figure 5-9. Measurement of Two Signals Having Equal Amplitudes , RBW = 30 kHz Figure 5-10. Measurement of Two Signals Having Equal Amplitudes , RBW = 10 kHz Remember, the resolution bandwidth must be equal to or less than the frequency separation of the signal.

  • Page 92: Measurement Of Two Signals Having Unequal Amplitudes

    Chapter 5 Spectrum Analyzer Measurements Measurement of Two Signals Having Unequal Amplitudes Typically, in real world environments, closely spaced signals do not have equal amplitudes. Often, the difference between closely spaced signals can be as much as –60 dB. To resolve two signals of unequal amplitude, the resolution bandwidth must be less than or equal to the frequency separation of the two signals (the same as resolving two equal amplitude signals).
  • Page 93 Chapter 5 Spectrum Analyzer Measurements Step 6. Change the frequency in the second source from 1900.100 MHz to 1900.050 MHz gradually and observe the effect.

    Software Tools Introduction This chapter provides a description of the Anritsu Software Tools program. Software Tools is a Windows 95/98/NT4/2000/ME/XP program for transferring measured traces, along with markers and limit lines, to the PC display. The program help function provides on screen instructions on display modification, trace overlay, uploading and downloading traces, and multiple plot printing.

  • Page 112: Uploading Antenna Factors

    Chapter 7 Software Tools Program Antenna used for radiated emissions testing are individually calibrated (the antenna factors can be measured directly) at all appropriate distances. The calibrations produce values that are defined the “equivalent free space antenna factor.” The calibration procedure corrects for the presence of the reflection of the antenna in the ground plane, giving the value that would be measured if the antenna were in “free space.”...
