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: PQZZTG8207UA
• Batch file CD-ROM for setting: PQZZTG8207UA
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-
tance. Then you can use it as a JIG Cable for both TCD300
and TCD500 series. (It is an upper compatible JIG Cable.)
11.1.2. PC Setting
11.1.2.1. Connections
Connect the AC adaptor to CN2 (base unit).
Connect the JIG Cable GND (black) to J104.
Connect the JIG Cable RX (red) to J103 and TX (yellow) to J102.
Note:
*: COM port names may vary depending on what your PC calls it.
