All voltage levels must be measured at High power transmission.

The RF and IF sections are measured by using a spectrum analyzer

.

After setting the standard (1 kHz, 3 kHz Dev

.) deviation, each voltage

of the AF section is measured by using an AF VTVM or osciloscope.

The level for each point is measured without removing parts or cutting

the pattern.

All voltage levels must be measured after setting the AF output volt-

age at 0.58V rms.

The RF and IF sections are measured by using a spectrum analyzer

.

Each voltage of the AF section is measured by using an AF VTVM or

osciloscope.
