Main Menu - Frequency Table (Inner Window)
Channel Table
The Channel Table shows the following parameters for each of the 80 or 256 channels,
as appropriate:
Channel No Parallel (logic lines) code required to select this channel, where 1
represents a connection to 0v, closed contact to 0V or logic low.
Tx Frequency The transmit frequency.
Rx Frequency The receive frequency (which may be different if an Rx offset has
been selected).
Rx Offset The amount by which the Rx frequency is higher than the Tx
frequency.
Unit Information
This box is display only and cannot be edited.
File Name The name of the firmware running in the unit.
File Version The version of firmware running in the unit.
File Date The date of the firmware running in the unit
S/N The serial number of the unit.
Number of Channels How many channels are programmed and may be selected
during operation.
Maximum Frequency The software assumes a 5MHz switching bandwidth to
calculate the Maximum Frequency from the Minimum
Frequency and uses this to calculate the frequencies in the
drop-down list displayed when selecting channel frequencies.
Minimum Frequency The minimum frequency refers to the transmit band, and is
used by the software as a base-line for all other frequency
information. The software will not allow a channel to be set to
a frequency below this minimum (or, in the case of a received
channel, this frequency plus the receive offset). This
frequency is stored in the non-volatile EEPROM in the unit.
