Adjustment and Measurement Methods
DEV adjustment method
Lch adjustment
Input the reference input (–38dBm/400Hz) to the MIC input (Pin 62) and adjust the voltage applied to Pin 36
(V36) so that the Pin 24 output reference frequency deflection is 1.5MHz ± 60kHz.
When adjusting DEV, connect a 10k
load resistor between Pin 24 and GND as shown in the electrical
characteristics measurement circuit.
Rch adjustment
Input the reference input (–38dBm/400Hz) to the MIC input (Pin 4) and adjust the voltage applied to Pin 16
(V16) so that the Pin 24 output reference frequency deflection is 1.7MHz ± 30kHz.
When adjusting DEV, connect a 10k
load resistor between Pin 24 and GND as shown in the electrical
characteristics measurement circuit.
Reference FM modulation distortion factor measuring method
Demodulate the Pin 24 output into the audio signal with the reference demodulator under the same conditions
as for DEV adjustment above, then measure the distortion factor.
BPF adjustment method
Input 15mVp-p, 1.625MHz signal to Pin 22 and adjust the voltage applied to Pin 26 (V26) so that the output
level when the SW of Pin 23 is switched to "a" (1.7M BPF output) and the output level when the SW of Pin 23
is switched to "b" (1.5M BPF output) are equal.
When adjusting BPF, connect a 4.7k
load resistor between Pin 23 and GND as shown in the electrical
characteristics measurement circuit.
Fader adjustment method
Input the reference input (–38dBm/ 400Hz) to the MIC input (Pins 62 and 4) and adjust the output level of Pins
49 and 52 with the voltage applied to Pin 3 (V3).
