If necessary, check power meter calibration and power level settings per
procedures in Section 5 – Maintenance of this manual.

a. Check output spectrum for suppression of adjacent channel IMD
sidebands per recommended spectrum mask.
b. Activate RTAC correction system via exciter screen as per instruc-
tions in exciter manual.
c. Verify RTAC correction system has properly suppressed out-of-band
IMD emissions with spectrum analyzer or other monitoring device.

to return equipment to Harris or ship equipment to another site at a
future date.
