TK-2102G

SG output level for obtaining 12dB / SINAD when injected to each 

point through a 470pF coupling capacitor

.

Measure the 1st Local level on a RF VTVM.

Modulate the AF level with a frequency of 1kHz and deviation 

of 1.5kHz (Narrow), 3kHz (Wide). Then take the signal from the 

signal

 generator

 output

 when

 set

 to

 -53dBm

 and

 obtain

 the

 

level shown on an AF VTVM when the AF output has been ad-

justed to 0.63V

rms with the AF vol.

Measure the audio frequency on an AF VTVM and radio frequency 

on a RF VTVM at high impedance.

Set

 the

 MIC

 input

 obtain

 a

 moduration

 factor

 of

 60%

 with

 the

 

transmit frequency at center and a modulation frequency of 1kHz.
