Cooling G3L-850-160 MCPA 1.4.3 Feed-forward Loop Control Circuits The primary function of the first loop is to amplify the carrier signals and isolate an error signal for the second loop. It does this by amplifying the carrier signals and isolating an error signal which is passed to the second loop. The first loop control section phase shifts the main input signals by 180 degrees and constantly monitors the output for correct phase and gain.
G3L-850-160 MCPA 1.6 Power Distribution Power Distribution The host system provides +27 VDC power for the MCPA. The DC/DC converter and voltage regulator in the MCPA converts the +27 VDC to +15 VDC, +9 VDC, +5 VDC, and -5 VDC for internal use. The MCPA has no built-in short-circuit protection. The MCPA operates at full power if the system DC supply is within 26 to 30 VDC. The MCPA shuts down if the applied DC power is less than 21.5 VDC or greater than 30.5 VDC.

Chapter 4 Maintenance 4.1 Introduction This chapter contains instructions for periodic maintenance, testing and troubleshooting for the G3L850-160 Multi-Carrier Power Amplifier (MCPA). 4.2 Periodic Maintenance NOTE Check your sales order and equipment warranty before attempting to service or repair unit. Do not break seals on equipment under warranty or the warranty will be null and void. Do not return equipment for warranty or repair service until proper shipping instructions are received from factory.
Return For Service Procedures G3L-850-160 MCPA CAUTION: Do not slam the MCPA into the system during installation. Using excessive force can damage the MCPA connector. CAUTION: When removing the MCPA from the system, support the MCPA to prevent the rear of the MCPA from suddenly dropping when the guide rail disengages from the track. Dropping the MCPA can damage the rear multi-pin connector. The MCPA weighs approximately 28.60 lbs. (12.97 kg). Table 4-3 MCPA Removal and Replacement Step 4.
