Spectrum analyzer with input impedance should used test video output level. Measured value (dBm) used calculate output according following relationship: Output (dBµ) (dBm) terminal direct reading value Measured after demodulating standard demodulator. 2MHz component carrier (fc) level. Adjust level obtain deviation ±30kHz measure harmonic distortion after demodulating with standard demodulator. Video determined measuring ratio (dB) chroma beat video carrier level when signal spectrum analyzer.
