11 Measurements and Adjustments
11.1. The Setting Method of JIG (Base Unit)
11.1.1. Preparation
11.1.1.1. 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).
• 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
• Oscilloscope
11.1.1.2. JIG and PC
• Serial JIG
JIG Cable: PQZZ1CD300E*
• PC which runs in DOS mode
• Batch file CD-ROM for setting: PQZZTG8227UA
• Batch file CD-ROM for setting: PQZZTG8227UA
Note:
*: If you have the JIG Cable for TCD500 series
(PQZZ1CD505E), change the following values of resis-
tance. Then you can use it as a JIG Cable for both TCD300
and TCD500 series. (It is an upper compatible JIG Cable.)
(PQZZ1CD505E), change the following values of resis-
