FM Dynamic Threshold C/N Measurement

Measurement Conditions:

•

Input signal: 1210 MHz, –30 dBm

•

Output Terminal: VIDEO OUT

•

Video Modulation: Color bars, 24.0 MHz p-p (peak-to-peak)

•

Pre-emphasis: 625

•

System switch: 625

•

The C/N must be calibrated.

Measurement Procedure:

Adjust the variable noise attenuator, and read the attenuator value just after
noise begins to appear on the TV monitor. Take the C/N value at this time as the
measured value.

Measurement Specification:

FM Dynamic Threshold C/N:

≤

13.5 dB
