Several types of RF tests can be conducted for electronics to evaluate their RF performance. These tests include:
Assess the performance of the device’s RF transmitter, including output power, frequency accuracy, modulation quality, and spurious emissions.
Spurious Emission Tests
Verify that the device does not emit unintended or harmful signals outside of its allocated frequency range, which could cause interference to other devices.
Radiated and Conducted Emission Tests
Determine the level of electromagnetic emissions from the device, both radiated (through the air) and conducted (through power and signal cables), to ensure compliance with regulatory limits.
Evaluate the ability of the device’s RF receiver to accurately receive and process signals, measuring parameters such as sensitivity, selectivity, and adjacent channel rejection.
Focus on the characteristics of the device’s antenna, including antenna gain, radiation pattern, impedance matching, and efficiency.
Receiver Blocking and Desensitization Tests
Assess the device’s ability to withstand strong adjacent signals without degradation or interference.
Frequency Range and Channel Occupancy Tests
Ensure that the device operates within the designated frequency range and adheres to the allocated channel occupancy requirements.
Modulation Accuracy Tests
Measure the accuracy and fidelity of the device’s modulation schemes, such as amplitude modulation (AM), frequency modulation (FM), or phase modulation (PM).
