Preparation for During the measurements, set the modulation
checking modula- analyzer as follows when there is no
tion adjustment specific requirement.
HPF OFF
LPF 20 kHz
De-Emphasis OFF
Detector (P-P)/2
Connect the modulation analyzer after
setting above conditions, through
the attenuator to the antenna terminal.
Connect an oscillo-scope, distortion meter
and a level meter to the modulation
analyzer’s detection output terminal.
Connect a millivolt meter or a 600 ohm out-
put impedance CR oscillator to the trans-
ceiver’s mic terminal.
