Aural Carrier Level - Allows user to set aural carrier level relative to visual carrier level.
Processor is factory tested at –10 dBc (decibels below visual carrier).
Input Source – Allows the user to select between cable HRC, cable standard or off-air.
Input Select – Allows the user to select the desire channel for input signal.
Output Select – Selects the desired channel of operation. If you require a lower channel
than the one currently displayed, push the toggle switch down. The channels will
change one at a time as many times as you press the switch. Holding the select switch
in the up or down position will “scan” to the desired channel. It is normal for the
frequency lock LED to turn off during and for a few seconds after, changing channels.
The switch must be held up or down initially for three seconds. This helps to ensure that
no accidental channel changes will occur.
Output Level – Sets visual carrier output level.
RF Out Test Point – Provides a sample of the RF output level which is 20 dB below the
actual value. RF test point is only a relative indicator of the actual RF output level and
may vary. All RF operating measurements should be made at the RF output of the unit.
RF Output - Modulated Audio/ Video output capable of +60 dBmV levels using built in
low distortion hybrid amplifiers.
