Most radio frequency (RF) telecommunications services are globally regulated by national laws (FCC, R&TTE directives, IC, etc.). These laws ensure that radio communication products use the allowed radio spectrum with minimal interference to other radio services or equipment. These laws also address the potential safety hazards of human exposure to radio frequency energy
Radio testing includes:
1. RF power output; Modulation characteristics
2. Bandwidth occupation; Conducted Stray Emission
3. Adjacent Channels Continuous and Translated
4. Frequency Stability with Temperature
5. Relationship between Output Power Stability and Power Supply Voltage
6. Transmission Time, Rate, and Duty Cycle; Compatibility of hearing aids
Wireless testing products include:
1. Frequency hopping and spread spectrum digital transmission systems
2. Wi Fi and WLAN 802.11a/b/g
