12 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.33)
12.1. Equipment Required
• Digital multi-meter (DMM): it must be able to measure voltage and current.
• Oscilloscope.
• Frequency counter: It must be precise enough to measure intervals of 1 Hz (precision; ±4 ppm)
Hewlett Packard, 53131A is recommended.
• DECT tester: Rohde & Schwarz, CMD 60 is recommended.
This equipment may be useful in order to precisely adjust like a mass production.
12.2. The Setting Method of JIG
<Preparation>
• Serial JIG cable: PQZZ1CD300E*
• PC which runs in DOS mode
•
Batch file CD-ROM
for setting: PNZZTG7621M
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.)
12.2.1.
Connections (Base Unit)
Connect the AC adaptor.
Connect the JIG Cable GND (black).
Connect the JIG Cable RX (red) and TX (yellow).
Note:
*: COM port names may vary depending on what your PC calls it.
