Anritsu MT8221B BTS Master Base Station Analyzer
The BTS Master MT8221B and MT8222B are high-performance handheld base station analyzers that have been specifically developed to support the emerging 4G standards as well as installed 2G, 3G and WiMAX networks. The MT822xB platform introduces:
- 20 MHz LTE modulation quality testing
- Vector Signal Generator (400 MHz to 6 GHz) for comprehensive receiver testing
- 30-MHz Zero-Span IF Output for external demodulation of virtually any other wideband signal
The BTS Master features over 30 analyzers in one to meet virtually every measurement need. Standard features are:
- 2-port Cable and Antenna Analyzer: 400 MHz to 4 GHz
- Spectrum Analyzer: 150 kHz to 7.1 GHz
- Power Meter: 10 MHz to 7.1 GHz
Meeting Key Performance Indicators (KPIs)
Degradation in KPIs, such as dropped call and/or blocked call rates due to a malfunction at the cell site or due to interference, can be easily and accurately diagnosed down to the base station field replaceable unit (FRU) or the offending interfering signal with the BTS Master.
Line Sweep Tools (LST)
LST is a PC program that post processes Antenna, Cable, and PIM traces. It provides a powerful trace analysis and report generator for line sweepers.
Master Software Tools (MST)
MST is a PC program that post processes spectrum analysis traces collected on your instrument. It provides a powerful data analysis tools for spectrum clearing and interference monitoring. With Anritsu’s design know-how and demanding production testing and performance verification you can count on the BTS Master to give you years of reliable dependable service.
Cable and Antenna Analyzer
The BTS Master features 1-port and 2-port Cable and Antenna Analyzer and a PIM Analyzer to be able to test and verify the performance of nearly every feed-line and antenna component. This includes:
- Connectors
- Cables/Jumpers
- Antenna Isolation
- Diplexers/Duplexers
- Tower Mounted Amplifiers
The goal of these measurements is to maximize the coverage, data rate and capacity with problem-free antenna systems minimizing dropped calls and blocked calls for a good customer experience.
Antenna Systems Failure Mechanisms
Maintenance is an on-going requirement as antenna systems’ performance can degrade at any point in time due to:
- Loose connectors
- Improperly weatherized connectors
- Pinched cables
- Poor grounding
- Corroded connectors
- Lightning strikes
- Strong winds misaligning antennas
- Rain getting into cables
- Bullet holes/nails in the cable
- Intermodulation of multiple signals
Making Measurements Easier
The BTS Master provides features for making measurements easier to perform and to analyze test results such as:
- FlexCal eliminates the need to recalibrate when changing frequencies
- High RF Immunity for testing in harsh RF environments
- Trace OVerlay compares reference traces to see changes over time
- Limit Lines and Alarming for providing reference standards
- High Power output to test tower-top components without climbing the tower
- Internal Bias-Tee to power up TMAs for testing when off-line
- GPS tagging of data to verify location of tests
- Line Sweep Tools for post-analysis and report generation
Spectrum Analyzer
The BTS Master features the most powerful handheld spectrum analyzer for field use with unmatched performance such as:
- Sensitivity
- Dynamic Range
- Phase Noise
- Frequency Accuracy
- Resolution Bandwidth (RBW)
The goal of the Spectrum Analyzer’s measurements is to be able to monitor, measure, and analyze RF signals and their environments. It finds rogue signals, measures carriers and distortion, and verifies base stations’ signal performance. It validates carrier frequency and identifies desired and undesired signals.
Simple But Powerful
The BTS Master features dedicated routines for one-button measurements and for more in-depth analysis the technician has control over the setting and features not even found on lab-grade benchtop spectrum analyzers, for instance:
- Multiple sweep detection methods - true RMS detector, quasipeak, ...
- Multiple traces and control - three traces, trace math, ...
- Advanced marker function - noise marker, frequency counter, ...
- Advanced limit line functions - one-button envelope creation, relative, ...
- Save-on-Event - auotmatically saves a sweep when crossing a limit line
- Gated sweep - view pulsed or burst signals only when they are on, or off
- I/Q waveform capture - transfer captured signals for further analysis and troubleshooting
Power Meters
The BTS Master offers as standard a builtin Power Meter utilizing the Spectrum Analyzer and an optional High Accuracy Power Meter requiring external power sensors.
Setting the transmitter output power of a base station properly is critical to the overall operation of a wireless network. A 1.5 dB change in power levels means a 15% change in coverage area.
Too much power means overlapping coverage which translates into cell-tocell self interference. Too little power, too little coverage, creates island cells with non-overlapping cell sites and reduced in-building coverage. High or low values will cause dead zones/dropped calls, lower data rates/reduced capacity near cell edges, and cell loading imbalances/blocked calls.
