LEVEL DIAGRAM / 电平图

To make measurements in the AF section, con-

nect the AC level meter. (ANT input : -53dBm,

1kHz FM, 3kHz DEV(WIDE).)

In the RF section, use a 1000pF coupling capaci-

tor. (The display shows the SSG input value re-

quired to obtain 12dB SINAD.)

TK-3148

AG is set to the MIC input becomes 3kHz DEV.

at 1kHz MOD. (WIDE)

To make measurements in the AF section, con-

nect the AC level meter.

In the RF section, use a 1000pF coupling capaci-
