IEC 60107: TV Receiver Measurements — RF Front-End Test Methods That Survived the Analog Era

TV Receiver Measurement Standards — Analog-Era Methods Still Define Digital RF Testing

IEC 60107-4:1999 specifies television broadcast receiver measurement methods. While CRT televisions are history, the RF front-end performance metrics they established — sensitivity, selectivity, intermodulation distortion — remain the reference framework for all digital TV and broadband receiver testing.

Three core metrics still in use: (1) Noise Figure (NF) — the receiver first-stage amplifier determines overall system noise performance. (2) Third-order Intercept Point (IP3) — measures receiver linearity in multi-signal environments, critical for digital TV receiving multiple channels simultaneously. (3) Adjacent-channel selectivity — during the digital transition, adjacent channels may simultaneously carry analog and digital signals.

TN Lab — Analog TV standards are gone. The RF test metrics they defined remain core to receiver design.
