TB8100 Service Kit User’s Manual Working With the Channel Table 119Channel Spacing The nominal channel spacing of the channel (the actual channel spacing isdetermined by the interval between this channel and the adjacent channels inthe channel table). Channel spacings correspond to the following IF bandwidthsand transmit deviations.If the channel is assigned a custom profile, the receiver can have one channelspacing while the transmitter has another. In this case, the channel table displaysthe receiver channel spacing.ButtonsA row of buttons along the bottom of the channel table (Configure > BaseStation > Channel Table) lets you work with channels. You can add or removechannels, create a whole new block of channels, or rearrange them into a betterorder.Insert New Inserts an additional channel at the end of the channel table. The channel isidentical 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 theproperties of the selected channel, except that the channels all have a channelspacing that you specify. See “Block Copying Channels” on page 121 for moreinformation.Move Up Shifts the current row above the previous row, effectively renumbering it withthe previous channel number. You can use Move Up and Move Down to givethe list of channels a more logical or tidy order, or to group channels inparticular ways.Important: Move Up and Move Down assign a different number tothe channel. If you use them, you may need to alter the defaultchannel selection, any external channel selection, and any TaskManager actions that change channel.Move Down Shifts the current row below the previous row, effectively renumbering it withthe 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.See “Importing Channels” on page 122.Export Lets you save a set of this base station’s channels to a file so that you can importthem into other base stations.
