CI-PM-3 Paging Modulator Instruction Manual 3-1
3 ALIGNMENT PROCEDURE AND INSTALLATION
3.1 General
The CI-PM-3 Paging Modulator is by default configured for stand-alone base station paging, using
2-Level paging data with a binary polarity of 1, and using the on-board +/-0.03 PPM 10 MHz
OCXO. Table 4-4 contains a complete list of CI-PM-3 default jumper settings. The CI-PM-3 can
also be configured for 4-level signal (base transmitter only) paging, remote paging, link repeater or
higher stability operation. Each of these configurations is covered separately in the following
sections.
3.2 Repair Notes
Removal and replacement of surface mount components should be performed only in specifically
designed surface mount rework and repair stations complete with electrostatic discharge (ESD)
protection.
To help prevent damage to the circuit board pads when removing Surface Mount Solder Jumpers, it
is recommended that solder braid be used in place of manual vacuum de-soldering tools.
3.3 Recommended Equipment List
Alignment of the CI-PM-3 requires the following test and radio equipment, or its equivalent:
• Power Supply: Regulated +13.8 VDC at 2 A
• Oscilloscope / Multi-meter: Fluke 97 Scopemeter
• Current Meter: Fluke 75 Multi-meter
• Radio Communications Test Set: Marconi Instruments 2955R (W/External Reference)
• Sub-rack: Daniels SR-3 Series 19” Sub-rack
• System Monitor: Daniels SM-3 Series System Monitor
• Transmitter Module: Daniels Enhanced Performance VT-3 / UT-3 Series
• Extender Card and Cable: Daniels EC-96K, 96 Pin Extender Card and Cable
• Alignment Tool: Johanson 8766
Note: It is highly recommended that the Radio Communications Test Set be frequency locked to
an external 10 MHz reference (WWV or GPS), especially if the factory-adjusted frequency
settings are to be altered in any way.
