[F] Set REFin frequency and channel spacing

To access this command in the program, select a board in the “Define boards to program” screen and
then press [Q]! . This will place you in the “Select from the available options” screen. The command [F] is
on this screen.

See page 23 of this document for a sample screen shot of this command.

This command prompts the user to input two values. First, a decimal value, in the form of
XX MHz + XXX kHz, to set the reference frequency of the targeted board. The program default frequency
is displayed along with the current value. The user may leave the reference frequency value as is by
entering return. A second input, in the form of XX MHz + XXX kHz, sets the channel spacing (step size)
of the targeted board. The program default step size is displayed along with the current value. The user
may leave the step size as is by entering return.

The inputs are validated by checking that the step size remains

≤

2 MHz (

≤

1 MHz for the ’220) for all

boards. The entered frequency is validated to ensure that the new reference frequency / new step size is
< 8191 and is an even multiple of the new channel spacing.

Finally, the RCOUNTER of the R register is set with the value of (new reference frequency / new channel
spacing) and R register is written to the targeted board. Then the ACOUNTER and NCOUNTER are re-
set to the previous frequency using the new channel spacing (previous frequency / new channel spacing)
and the A register is written out.

Note that due to the complexity of error checking in dual mode, REFin frequency and channel spacing
may not be modified.
