6.4. Performing Analog TV measurements
The terrestrial measurement interface allows also performing measurements on Analog TV
signals. As the meter auto-detects the modulation type, in presence of an analog signal the
interface will switch to the correct view automatically:
As shown above, the basic screen visualizes the tuning paramenters (top bar) and the Video
carrier level; on the right side, the A/V content is automatically decoded and visualized.
Touching the screen over the measurement bar or pressing
TV button on the keyboard will
switch to the second screen:
On the left side, three measurement bars appear: RF Video carrier level, signal to noise ratio
and Audio to Video carrier ratio; in case of stereo audio, also the A/V ratio for the second audio
carrier is displayed. In this second screen, the video and audio decoding is not available, as the
meter should be able to measure the different components of the signal.
