KNB-14/KNB-15A (Ni-Cd BATTERY)
LEVEL DIAGRAM
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 Without Local Level.)
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 ca-
pacitor.
