Carrier Level Difference (V-A) Measurement

The ST5128 can measure the difference in power levels between video and

audio carriers of a defined channel.

While in the Single Channel Measurement Mode Main Menu screen, press the

F2 (V-A) soft key. (Note: The V-A function will not work unless the channel to be

measured has already been selected). The resulting V-A measurement display is

shown in figure 5. Both the video and audio carrier power level measurements

are also displayed.

F2 – MID- Selects the channel number midway between the 1

and last channels

in the table.

F3 – TOP – Selects the highest channel number in the predefined channel table.

F4 – ESC – Exits out of the V-A Measurement Mode. Returns to the single

channel measurement mode main menu.
