138 Part F: Configuring Channels
© Tait Electronics Limited December 2007
Power
The RF power output that the channel is configured to provide when it is
provided with mains power. (The channel profile may specify a different power
output for battery power).
Channel Spacing The nominal channel spacing of the channel (the actual channel spacing is
determined by the interval between this channel and the adjacent channels in
the channel table). Channel spacings correspond to the following IF bandwidths
and transmit deviations.
If the channel is assigned a custom profile, the receiver can have one channel
spacing while the transmitter has another. In this case, the channel table displays
the receiver channel spacing.
Buttons
A row of buttons along the bottom of the channel table (Configure > Base
Station > Channel Table) lets you work with channels. You can add or remove
channels, create a whole new block of channels, or rearrange them into a better
order.
Insert New
Inserts an additional channel at the end of the channel table. The channel is
identical to the last channel in the table except for the channel number.
Insert Copy
Inserts a copy of the selected channel at the end of the table.
Block Copy
Lets you add a number of channels to the channel table, each with the
properties of the selected channel, except that the channels all have a channel
spacing that you specify. See
“Block Copying Channels” on page 140 for more
information.
Move Up
Shifts the current row above the previous row, effectively renumbering it with
the previous channel number. You can use Move Up and Move Down to give
the list of channels a more logical or tidy order, or to group channels in
particular ways.
Important: Move Up and Move Down assign a different number to
the channel. If you use them, you may need to alter the default
channel selection, any external channel selection, and any Task
Manager actions that change channel.
Move Down
Shifts the current row below the previous row, effectively renumbering it with
the next channel number.
Delete
Removes the current row from the channel table.
Import Lets you add a set of channels from a file exported from another base station.

“Importing Channels” on page 141 .
