Single Channel - Analog Results
Red blocks indicate the predefined threshold window for the measurement parameter.
The effect of noise or poor C/N on analog video carriers is described below.
The average power changes depending on the picture content e.g. dark scenes have a higher average power than bright scenes.
Using sync pulses, the carrier is at its peak power and it does not change from scene-to-scene; therefore, peak power has become
the standard for analog video carrier level measurements. The CX380C measures the peak level for analog carrier.
