keys or by entering a value using the numeric keypad and then

pressing the ENTER key. The FCC specification for C/N measure-

ments is a bandwidth of 4.200 MHz. CATV organizations outside of

the United States may have different requirements.

Noise Offset Frequency Adjustments

The frequency at which the noise level is measured is the Carrier

frequency plus the noise offset. To adjust the noise offset, cursor to

the Noise Offset selection. The offset can be adjusted by using the

UP and DOWN arrow keys or by entering a value using the numeric

keypad and then pressing the ENTER key.

Tilt Channel

designated as scrambled, the sweep will only look at the video carrier

as a sweep reference, instead of both the video and audio carrier.

on most screens.
