AQD Quick Set-Up Instruction Guide
The Quick Set-Up instructions are provided as a checklist
of the minimum steps required to install and program the
ATSC/QAM Demodulator.
1. Verify RF input levels
a. Signal acquisition range is -20 to +20 dBmV — -10 to +10
dBmV is the desired optimum level
2. Verify all cable connections — (Refer to page 11 for detailed
instructions)
a. Check to make sure the power/data cables are connected to
the correct location on the PCM and the respective modules
to ensure proper communication
3. Program the appropriate DEMOD MODE for each module
—
8VSB or QAM (Refer to page 16 for detailed variable
instructions)
4. Program the appropriate CHANNEL PLAN for each module —
Broadcast, Standard CATV, HRC or IRC
5. Perform a SCAN on each or all modules —
it is not recommended
to operate the unit when a scan is in process
a. A scan must also be performed each time the Demod Mode
is changed
6. Program the appropriate desired channel in the TUNE
CHANNEL menu sequence
a.
NOTE:
A scan must be performed prior to selecting
