3 3 Main Functions Spectrum Analyzer The Base Station Analyzer has a general purposed spectrum analyzer which is the most flexible test tool for RF analysis. Beyond this basic spectrum analysis functionality, a built in RF measurement application provides a one button RF measurements including: Channel Power Adjacent Channel Power Spectrum Emission Mask Occupied Bandwidth FM/AM Audio Demodulation Interference Analyzer The Base Station Analyzer has an interference analyzer function which is the most effective way to identify periodic or intermittent RF interference. A spectrogram display allows the user to capture spectrum activity while displaying frequency, power and time information. The signal tracking capability is particularly useful for observing signal strength at a single frequency over time with an audible indication.

4 4 Transmission Analyzer The modulation measurement suite of the Base Station Analyzer provides not only RF parametric analysis but also modulation parametric analysis of modern wireless communication systems. Built-in wireless standard test procedures allow users to test each of the following items with a single button action. CDMA2000 / EVDO Analyzer CDMA Channel Power CDMA Adjacent Channel Power CDMA Spectrum Emission Mask CDMA Code Domain Power Frequency Error Time Offset Wave Quality Auto PN Search Carrier Feed Through Codogram RCSI (Received Code Signal Indicator) EVDO Analyzer EVDO Channel Power EVDO Adjacent Channel Power EVDO Spectrum Emission Mask EVDO Power vs Time Slot Average Power Pilot Power MAC Power Traffic Power On/Off Ratio Idle Activity EVDO Code Domain Power Frequency Error Time Offset Auto PN Offset Search Rho (Pilot, MAC, Traffic) EVM (Pilot, Mac, Traffic)' Carrier Feed Through Codogram RCSI (Received Code Signal Indicator)

7 7 Over The Air Measurements The Base Station Analyzer provides over the air measurements for a quick performance characterization of the base station. This function is especially useful in testing cell sites which are not easily accessible. Channel Scanner The Base Station Analyzer has the function of measuring multiple transmitted signals. The Channel Scanner can measure up to 20 channels in GSM, CDMA, or WCDMA networks. Using existing format-based or custom parameters, the user easily verify improper multi-channel power levels. GSM Channel Scanner The Base Station Analyzer has the function to display channel power and related information up to 128 GSM down link signals. This channel scanner can quickly identifies improper power levels that affect network performance; this can be done either over the air or directly connected to the cell site.

8 8 Cable and Antenna Analyzer The Base Station Analyzer can perform also the function of an antenna and cable analyzer that measures cable loss, distance to fault (DTF) voltage standing wave ratio (VSWR), Return Loss (RL) and insertion gain / loss. The antenna and cable analysis functionality can characterize active and passive devices such as cables, filters, amplifiers, antennas and multiplexers. In a one port measurement, users can measure feed-line cable loss, DTF location, and Antenna VSWR/RL. And with two ports measurements users can perform gain measurements, insertion loss and isolation; particularly useful for filers, amplifiers, Tower Mounted Amplifiers (TMA), RF path gain, and Antenna isolation. Power Meter The Base Station Analyzer can perform two power testing methodologies: Internal, for standard power measurements without the assistance of external power sensors. External, for high accuracy power measurements with the assistance of external power sensors. The internal power meter with no additional power sensors uses the spectrum analyzer functionality. It is a simple test methodology with reasonable accuracy. On the other hand, external power sensors perform power measurements more accurately. The Base station Analyzer can be equipped with a Terminating Power Sensor or with a Directional Power Sensor (through-line) which has the advantage to minimize service disruption and covers an ultra-wide power range. Power displays in either dbm or Watts. Upper/limit can be set during pass/fail measurements.

9 9 E1/T1 Analyzer The Base Station Analyzer provides a testing solution for E1/T1 transmission lines. Various test modes are available for the user, including: Mode: Term, Monitor, Bridge, Loop Frame: PCM30, PCM31, Unframed Code: AMI, HDB3, B8ZS TX Pattern: 1-8, 1-16, ALL0, ALL1, 0101, 2E20 Alarm, Error Count and Logging Auto-Measure The Auto-Measure function provides an easily set up for testing, including the programming of measurement schedules such as starting time, duration; intervals and measurement parameters. Based on the user defined conditions, the Base Station Analyzer performs the tests and automatically stores the results.
