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. 
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.
