primary modulation method, to determine the Reflected Power
Calibration values:
EXAMPLE: Desired TPO of primary modulation format = 4600W
4600 x 0.03 = 138W for the RFL PWR CAL
STEP 9 Press [HOME, MORE, CONFIGURATION, C, B]. This will take you to
the screen in Figure 5-8. Re-adjust R128 until the A/D RFL PWR
reading is the value as calculated below:
Or use the following formula, based on your desired TPO for your
primary modulation method, to determine the A/D RFL PWR factor:
EXAMPLE: Desired TPO of primary modulation format = 4600W
A/D RFL PWR factor = 474

STEP 10 Press [HOME, MORE, CONFIGURATION, C, D]. The will take you to
the Reflected Power Cal screen and should look like Figure 5-9.
Set this screen to the correct value determined by the calculation in Step
8, above. Press and hold [D] and then press [BACK] to calibrate the
reflected power meter and save the information. The display will flash
“Calibration Done” very quickly at the bottom of the Diagnostics
Display.
