The Frequency Extended Local Oscillator Multiplier Amplifier (FELOMA) provides amplitude leveling and distribution of the first LO (3 to 7 GHz) to the Lowband assembly, RYTHM, SBTX, and the LO Synthesizer assembly. There are three ALC loops in the FELOMA. The main input ALC loop can have its sense voltage come from either the RYTHM/Lowband path or the Front Panel External LO out path. The 2nd ALC loop is used to level the power going into the sampler. The 3rd ALC loop is for the SBTX output. The SBTX output frequency is twice that of the LO.
The FELOMA requires eleven level adjustments and four bias adjustments. The voltages for each of these adjustments are printed on the FELOMA level. The voltages are measured with a DVM which is connected to a board attached to the Front End Driver A13J12 connector.
This adjustment should be performed after replacing the A21 or A13 assemblies.
