Test Equipment Required for Alignment
Test Equipment
1. Standard Signal Generator
(SSG)
2. Power Meter
3. Deviation Meter
4. Digital Volt Meter (DVM)
5. Oscilloscope
6. High Sensitivity
Frequency Counter
7. Ammeter
8. AF Volt Meter (AF VTVM)
9. Audio Generator (AG)
10. Distortion Meter
11. Spectrum Analyzer
12. Tracking Generator
13. 8Ω Dummy Load
14. Regulated Power Supply
The following parts are required for adjustment
1. Antenna connector adapter
The antenna connector of this radio uses an SMA termi-
nal.
Use an antenna connector adapter [SMA(f) – BNC(f) or
SMA(f) – N(f)] for adjustment. (The adapter is not provided
as an option, so buy a commercially-available one.)
2. Jig (chassis) for adjustment(part number A10-1392-03)
■ Use the jig as follows:
1. Insert the coaxial antenna connector into the jig.
2. Place the unit on the jig and fi x it with 12 screws q.
3. Solder the antenna terminal to the terminal of the unit.
Note: Supply power from an external power supply.
