ACCESSORIESSeveral optional accessory items have been designedfor use with the CPI 250 W L-band J Series CMPAs.Brief descriptions of the items now available are givenon the following paragraphs.Redundant SwitchingThe Switching System consists of an output switch,dummy load and local control unit. These assembliesare usually mounted on the upper part of a rack/cabinetintended to house the two J Series CMPAs. The circuitprovides 1:1 redundant protection with automatictransfer, or manual operation (local or remote) as selectedby the operator. Options are available for theaddition of an input power divider or a ganged inputtransfer switch.Remote Control PanelsThe Remote Control/Monitor panel is a rack-mountableunit 3.5 inches high that provides an output RFpower meter and all of the remote controls and indicatorslisted in this brochure. The panel requires a sourceof AC power and it does not include the interconnectcable from the J Series CMPA. The ideal interconnectcable would include two twisted pairs enclosed in ashield; several wire manufacturers build cable specificallyfor RS-422/485 applications. Since the RS-422/485 serial format is used, cable lengths are limited to4,000 feet.Remote control/monitor panels are also available foruse with the switching system and phase combinersystems.Phase CombiningThe Phase Combiner consists of a coaxial input dividernetwork and phase shifter and an output combiningsystem, to coherently combine the output RF power oftwo J Series CMPAs. The combined system thenbehaves as a single power amplifier with nearly twicethe RF output power of a single J Series CMPA. Thecombiner is a hybrid coupler, which combines the twoinputs with minimum loss.The combiner assembly is normally supplied mountedin the rack/cabinet which also houses the two J SeriesCMPAs to provide an integrated power-combined JSeries CMPA system.L-Band J Series CMPA (VZL-6943J2) 04/00 TD-78 14

SUPPORT SERVICESDocumentationCPI Satcom Division provides a commercial documentationpackage for all products. The content of thispackage is determined by the nature of the productconcerned, and the quantity is governed by contractualrequirements. The standard package for Satcompower amplifiers includes a comprehensive Operationand Maintenance Manual, outline and interface drawings,Manufacturing Test Report and spare parts lists.Outline and interface drawings provide dimensions andthe location and size of mounting holes, duct work, andwaveguide, so that site preparations can be accomplishedprior to receipt of the equipment.The Service Manual provides instruction for unpackingand installation, initial set-up, calibration, normal operation,maintenance and repair of the equipment. Themanual includes schematic diagrams, block diagrams,and wiring information sufficient for use by maintenancepersonnel.The Acceptance Test Report outlines the test performedlimits established. Space is provided on thetest report for recording and certifying the test results,consolidating all related information in one document.The spare parts documentation consists of a recommendedspare parts list to support the equipment for aone-to-two year period of operation. A CSI AcceptanceTest can be performed at customer’s optionwhich will repeat and verify results of selected performancetests that were already recorded in the standardacceptance test.Small training groups (up to five students) assure thecustomer that each student has an opportunity to participatefully in demonstration activities. Courses maybe conducted at the CPI factory or on-site. Courseduration varies from several days to one or two weeks,depending on the scope of work agreed upon and theskill level of the students.Field ServiceThe product support activity of CPI includes a staff ofexperienced, professional service technicians to assistusers in maintaining full performance from their CPIpower amplifiers. A telephone “hot line” permits accessto one of these technicians on a 24-hour per daybasis. Operational problems often can be diagnosed,corrective action prescribed, and normal operationrestored through such telephone consultation. Whencalled for, however, the service technicians are preparedto give on-site assistance.Product Support carries an large inventory of spareparts that can be made ready for shipment within 24hours. Coupled with a dedicated dial-in telephone line,this service is effective in aiding users to restore equipmentto operational status with minimum downtime.Technical assistance and factory approved replacementparts are also available at strategically locatedRegional Service Centers in the U.S.A., Europe andthe Pacific Rim.TrainingCPI Satcom Division is prepared to conduct trainingcourses covering the installation, operation and maintenanceof its equipment. The training course on highpower amplifiers consists of lectures using training material,such as technical manuals and drawings, plusactual operation and adjustments demonstrated on theequipment.L-Band J Series CMPA (VZL-6943J2) 04/00 TD-78 20
