Procedure for Getting a Channel Table
To download the current channel table(s) from the Install Profiler,
select the desired channel table’s name from the list of tabs at the
top of the Channel Tables window. Click on the Get button. The
table will scroll through the channels as this process takes place.
It may require a minute or so, depending on the number of
channels and the computer speed.

To Get All Channel Tables
All of the channel table may be downloaded at once, if more than
one table is used, but will take considerably longer. Use the
single channel mode if one is all that you need. To download all
of the channel tables click on the ALL.

Channel Table Information
Channel - NTSC channel number. Any 3-digit number or 4-
character alphanumeric may be assigned, if it has not already
been used.
character alphanumeric may be assigned, if it has not already
been used.
Frequency – The video carrier frequency of NTSC channels or
the center frequency of a digital channel. Note that this is the
center frequency of digital channels and not the frequency of the
typical video carrier for an analog channel. Changing the
Modulation type from an analog type to a digital type will
automatically change the frequency from the typical video
carrier frequency to the center frequency and vice versa. If you
change the frequency and then change the modulation type, the
PC-IP software will automatically change your frequency to the
wrong center frequency. If you plan to enter the center
frequency, set the modulation type first.

Offset - Frequency offsets may be programmed on any channel

in
±62.5 kHz increments from 0 to 3.0 MHz. Small offsets of
12.5 kHz are not required, since the IF resolution bandwidth
easily accommodates small offsets without errors.

Active (Yes/No) – The Install Profiler allows measurements on
that channel when Active Yes is chosen. Active no hides the
channel from the list of active test channels. These channels will
be skipped when using the arrow keys for channel selection and
will not be used in the automated SMART tests. All channels
remain available in the channel and frequency-tuning mode
when they are entered via the alphanumeric keys.
