8.5.10 Reading PCU "N" Coefficients

The Antenna PCU contains calibration coefficients that must be reloaded when the PCU is replaced.
The software procedure described here is used to display the coefficients which can then be recorded so that
they can be reloaded when the PCU is replaced.
Tools:
None
Part Location:
Values are read from the ac command.
Procedure:
1. The PCU must be operating and not initializing while the coefficient values are being read via the ac
command.
2. Enter ac.
3. Enter 1 or chain for the antenna.
4. Enter n0999. The reply will be the antenna type.
5. Record the value displayed, using the recording format shown in step 6 for the coefficient 0.
6. Enter the remaining six coefficient numbers (from column 3 of Table 8-1 on the following page) as in
step 4 (i.e., n1999 ENTER, n2999 ENTER, n3999 ENTER, . . .) and record the value for each as it is
displayed:
0: ______
1: ______
2: ______
3: ______
7. Enter reset to reinitialize the antenna.
4: ______
5: ______
6: ______
