Carrier-To-Noise Measurement

The Model Two measures C/N on the last channel selected in Level mode.

To enter the C/N screen, press 

C/N

.

The Model Two measures the C/N difference of the selected channel. First, it measures the Video
Carrier Level of the selected channel. The Video Carrier Level MUST be greater than 25 dBmV
(85 dB

μ

V) for the C/N function to operate.

If the measured Video Carrier is greater than 25 dBmV (85 dB

μ

V), the Model Two displays a

please wait... 

message prompt. Then, the Model Two measures the noise level away from the

Video Carrier and calculates the C/N ratio of the selected channel. The value of the C/N difference
is displayed on the screen.

If the Video Carrier is shut down as prompted on the display, the Model Two reads the noise in the
measured channel bandwidth and uses this to calculate the C/N ratio for improved accuracy.

The measured channel may be changed by using the 

UP

 and 

DOWN

 arrow keys.
