11 Measurements and Adjustments

This chapter explains the measuring equipment, the JIG connection, and the PC setting method necessary for the
measurement in Troubleshooting Guide (P.27)

11.1. Equipment Required

• DECT tester: Rohde & Schwarz, CMD 60 is recommended.
• Frequency counter: It must be precise enough to measure intervals of 1 Hz (precision; ±4 ppm).
Hewlett Packard, 53131A is recommended.
• Digital multi-meter (DMM): it must be able to measure voltage and current.
• Oscilloscope

11.2. The Setting Method of JIG

<Preparation>
• Serial JIG cable: PQZZ1CD300E*
• PC which runs in DOS mode
• Batch file CD-ROM for setting: PNZZTG9471B
