Chapter 1 Product Description 1.1 Introduction This manual contains information and procedures for the installation, operation, and maintenance of the EHP19 Integrated Power Transceiver (IPT). 1.2 Scope of Manual This manual is intended for use by service technicians familiar with similar types of equipment. It contains service information required for the equipment described and is current as of the printing date.
Functional Description from this block: control data and signal data. The control data determines parameters such as channel frequencies, signal ramp-up/ramp down and transmit power level. These functions are implemented in a Field Programmable Gate Array (FPGA). 1.3.2.2 Digital Up Converter (DUC) The DUC modulates individual symbol streams from the signal data stream on to baseband carriers and applies root-raised cosine channel filtering.
Functional Description FRONT REAR Figure 1-1 Integrated Power Transceiver Front and Rear Isometric View 1.3.3 Power Module The P-Mod is a multi-stage amplifier, which amplifies the low level signal from the AUC up to the RF output power level of +47.8 dBm (60.25 W). The P-Mod consists of a two-stage pre-driver, a driver amplifier and an output stage.
Functional Description 1.3.5 Operational States The IPT has three operational states: Operational, Disabled and Not Ready. The IPT remains in the Not Ready state during start-up until all parameters are met for the IPT to become operational. The IPT is normally in the Operational state: no faults are present, the IPT internal temperature is within limits, appropriate DC power is applied, and the IPT is producing RF output. The green operational (O) LED on the Man Machine Interface is lit.

Chapter 3 Operation 3.1 Introduction This chapter contains operating instructions for the EHP19 Integrated Power Transceiver (IPT). 3.2 Controls and Indicators The IPT provides one switch, four LED indicators, one ethernet connector, one serial connector and two RS-485 connectors as shown in Figure 3-1. Figure 3-1 IPT Indicators and Controls 3.2.1 Reset Switch The Reset recessed pushbutton switch allows the operator to reset the IPT control circuits.
Initial Start-Up and Operating Procedures 3.2.2 Status and Alarm Indicators MCPA alarm conditions are reported to the system as logic level signals through the rear connector. The front panel LED provides a visual reference for the operator of MCPA status. Refer to Table 3-1. The IPT ALARM (INT.) lights when a IPT fault occurs.
Chapter 4 Maintenance 4.1 Introduction This chapter contains the periodic maintenance, troubleshooting and removal and replacement instructions for the EHP19 Integrated Power Transceiver (IPT). NOTE 4.2 Check your sales order and equipment warranty before attempting any service or repair activity. Do not break the seals on equipment under warranty or the warranty will be null and void.
Return For Service Procedures 4.4.1 IPT Removal and Replacement Procedure Perform the following to remove and replace the IPT: WARNING: Ensure the RF power has been removed from the RF input cable before disconnecting or reconnecting the RF input cable. Table 4-3 IPT Removal and Replacement Step 4.5 Action 1 DIsconnect cables at the TX, RX0 and RX1 inputs. 2 Loosen the thumbscrews and slide the IPT out of the subrack.
