3-3

SCAN: Use the Scan mode to get a good look at absolute carrier

levels. In this mode a bar graph showing all carrier levels is

displayed.

SWEEP:

This mode injects a low level signal in vacant spectrum

areas, and transmits telemetry to any 3SR Receivers that

are connected to the system. Cable system carrier levels in

occupied spectrum areas are monitored and displayed in bar

graph format.

NOTE: Telemetry occurs only while the unit is in Sweep mode.

Selecting another mode will result in a loss of telemetry to

any Receivers connected to the system.

C/N: Measures the C/N (carrier to noise) ratio of the tuned

channel or frequency will be displayed.

HUM: Measures the hum modulation of the tuned channel, will

display in either % or dB as selected by the operator.

MOD: Allows the user to listen to the modulation of the tuned

channel of frequency and measure Depth of Modulation of a

video carrier.

SPECT: Provides a Spectrum Analyzer display, and CSO/CTB

measurements.
