REPAIR PROCEDURES

5.4. Jigs and Tools

5.4.1 Personal Computer (PC)
The PC (IBM compatible) is used as a Unit Under Test controller. This, in conjunction with the channel box software, allows all
of the test facilities normally provided through the keypad of the Unit Under Test.
The Microsoft Windows® 98SE, 2000 or XP operating system must be installed on the PC.
A Universal Serial Bus (USB) port must be installed on the PC if automatic RF calibration is to be performed.
5.4.2 PCB Repair Jig (Part No. JT00091)
The power cable has a large capacitor across the positive and negative leads to reduce the loading effect on the power
supply during RF calibration.
Therefore, it is important that the correct polarity of the cables is observed, otherwise serious damage will occur to the
capacitor.
The PCB Repair Jig provides the necessary connections between the PCB Assembly and external test equipment. It is
required for RF calibration. The following spares items are available for the PCB Repair Jig:
• PCB probe pins, pack of 3 (Part No. JT00092)
• RF probe (Part No. JT00084)
A cable with SMA female connector is provided to make the RF connection. An SMA to N-Type male adaptor will be required
to connect the Repair Jig to the service equipment. Cable losses for the RF connection are as follows:
A replacement RF Probe for the Repair Jig is available as a spares item.
