Note) Tuning is taken the peak point at 10.6 MHz output level ( VIN = 30 dBµ, non-modulation)

*1 : Conversion gain = 20 Log( ∆V (µV) ÷ 31.6)

∆V is the output difference at VIN = 30 dBµ and at VIN = 36 dBµ

*2 : Measurement is done at the detection output of the AN7233

Measure the ratio of output at fDIV = 22.5 kHz to that at fDIV = 0 Hz (modulation freq. 1 kHz)

*3 : Measurement is done at the detection output of the AN7233

Measures a peak voltage of the measurement time = within 500 ms (OK to 10 times)
