8.4 Select Channel Guide
This function allows you to select the active channel guide, if multiple guides are present on the unit. The
unit uses the channel guide to verify valid frequencies and to correlate frequencies with channel
numbers, in various areas of testing.
Note that:
• Only one guide may be active at any given time.
• You can view the channel listings in the active guide at any time with the View Channel Listings
function (see View Channel Listings on page 8-7).
• You can download new and/or updated guides to the unit as required (see Download RF Channel
Guide(s) on page 8-23).
8.5 View Channel Listings
From the main RF menu, View Channel Listings allows you to view two channel tables on the unit:
• The standard listing of TV channels and their associated frequencies (see EIA CATV tab on
page 8-7)
• The channel guide currently active on the unit, which should reflect the architecture under test (see
Lineup tab on page 8-8)
8.5.1 EIA CATV tab
This tab displays a list of channel numbers/designations and their associated frequencies supported by
the module tuner, according to EIA standards
[4]
. Channels in the active channel guide (see Lineup tab on
page 8-8) should each reference a channel from this list, which is how the unit determines the
frequency(ies) for testing. The information in this tab is fixed according to the firmware package on the
unit and cannot be changed by end users. For a listing of these channels, see Supported channels and
frequencies on page 8-27.
Column Description
CH Channel number or designation. Note the following:
• This is not the number displayed in test setup and results screens.
Rather, it is the number that should be referenced by a channel in
the active channel guide (Lineup tab on page 8-8), as applicable.
• Out-of-band (OOB) channels, if present, typically appear with an
OOB designation rather than a number.
Preliminary issue - Limited distribution only!
