Introduction

Analysis of Standard Technical Framework

Test Dimensions	Fixed Monitoring Station	Mobile Monitoring Station	Portable System
Applicable Scenarios	Long-term Fixed-point Monitoring	Dynamic Area Scanning	Temporary Task Deployment
Antenna Height Requirements	Protocol Specified Value (Usually 10m)	1.5-3m (Vehicle-mounted)	Adjustable (≥4m)
System Error	±2dB	±3dB	±2.5dB

Details of core test parameters

The standard requires that the test system must meet the following requirements: frequency range 100kHz-3000MHz, RBW/VBW 10Hz-3MHz adjustable, and channel power measurement function. Key equipment includes:

Spectrum analyzer: must have peak/RMS detection function
Measurement receiver: input impedance 50Ω, LNA noise temperature ≤298K
Test antenna: gain must be marked, polarization mode can be vertical/horizontal

Typical test process

Test point geographic information recording (latitude and longitude + altitude)
Antenna installation and system calibration (height error ≤0.5m)
Full-band scanning (VHF/UHF priority)
Signal parameter measurement (frequency/bandwidth/power)
Data recording and spectrum diagram storage

Key points of special business testing

Public mobile communication test case

When testing the GSM network, the following are required:

Forced frequency locking of BCCH channel (271kHz bandwidth)
Decoding of MCC/MNC/LAC parameters
Calculation of field strength according to the formula E=K+L+P+107

Standard implementation recommendations

It is recommended to establish an independent border monitoring database. The test report should include:

Signal source country identification (China/neighboring country code)
Exceeding standard signal classification (three categories: A/B/C)
Antenna height conversion data (see Appendix E)
