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
Note:
*: If you have the JIG Cable for TCD500 series
(PQZZ1CD505E), change the following values of
resistance. Then you can use it as a JIG Cable for both
TCD300 and TCD500 series. (It is an upper compatible JIG
Cable.)
Note:
*: If you have the JIG Cable for TCD500 series
11.2.1. Connections (Base Unit)
Connect the AC adaptor to DC-JACK (base unit).
Connect the JIG Cable GND (black) to GND.
Connect the JIG Cable RX (red) to URX and TX (yellow) to UTX.
Note:
*: COM port names may vary depending on what your PC calls it.
