Adjustment - Kenwood TK-90 Service Manual

TK-90
Required Test Equipment
1. DC Voltmeter (DC V.M)
1) Input resistance : More than 1MΩ
2) Voltage range : 1.5 to 1000V AC/DC
Note: A high-recision multimeter may be used. How-
ever, accurate readings can not be obtained for high-
impedance circuits.
2. DC Ammeter
1) Current range : 100mA, 1.5A, 30A, high-precision am-
meter may be used.
3. RF VTVM (RF V.M)
1) Input impedance : 1MΩ and less than 3pF, min.
2) Voltage range : 10mV to 300V
3) Frequency range : 10kHz to 500MHz
4. AF Voltmeter (AF V.M)
1) Frequency range : 50Hz to 10kHz
2) Input resistance : 1MΩ or greater
3) Voltage range : 10mV to 30V
5. AF Generator (AG)
1) Frequency range : 200Hz to 5kHz
2) Output : 1mV or less to 1V, low distortion
6. AF Dummy Load (DM. SP)
1) Impedance : 4Ω
2) Dissipation : 5W or greater
7. Oscilloscope
Requires high sensitivity, and external synchronization
capability (150MHz or greater).
8. Standard Signal Generator (SSG)
1) Frequency range : 50kHz to 30MHz
2) Output : –133dBm/0.1µV to 7dBm/1V
3) Output impedance : 50Ω
4) AM modulation can be possible
Note : Generator must be frequency stable.
9. Frequency Counter (f. counter)
1) Minimum input voltage : 50mV
2) Frequency range : 150MHz or greater
10. Noise Generator (Noise G.)
Must generate ignition noise containing harmonics
beyond 30MHz.
11. Audio Analyzer
12. RF Dummy Load
1) Impedance : 150Ω and 50Ω
2) Dissipation : 150W or greater
13. Power Meter
1) Impedance : 50Ω
2) Dissipation : 200W continuous or greater
3) Frequency limits : 30MHz or greater
14. Spectrum Analyzer
1) Frequency range : 100kHz to 140MHz or greater
2) Bandwidth : 1kHz to 3MHz
15. Tracking Generator
16. Directional Coupler
17. Monitor Receiver
18. Microphone
KMC-30, KMC-32, KMC-35 or KMC-36
19. Distortion Meter
20. Double Signal Pad (50Ω)
