CONDITIONS

(GAIN SEL) = 0, (AGC GAIN) = 0

 = SG2, Π= SG3

Input the SG1 (f = 2 MHz, V = 0.2 Vp-p) to

the SIN and measure the amplitude of the

AGCOUT. Increase the frequency and

measure the frequency when the amplitude

attenuates to –3 dB.

(GAIN SEL) = 7, (AGC GAIN) = 255

 = SG2, Π= SG3

Input the SG1 (f = 2 MHz, V = 8 mVp-p) to

the SIN and measure the amplitude of the

AGCOUT. Increase the frequency and

measure the frequency when the amplitude

attenuates to –3 dB.

(GAIN SEL) = 0, (AGC GAIN) = 0

SIN = GND1, (OFFSET) = 0, Â = 0 V,

Î=0V

Measure the voltage of the AGCOUT at BLK

= 3.3 V and define it VBO11.

Measure the one similarly at BLK = 0 V and

define it VBO12.

VBON = VBO12 – VBO11

(GAIN SEL) = 0, (AGC GAIN) = 0

SIN = GND1, (OFFSET) = 63, Â = 0 V,

Î=0V

Measure the VBO21 and VBO22 similarly to

above-mentioned method.

VBON = VBO22 – VBO21

(GAIN SEL) = 0, (AGC GAIN) = 0

 = SG2, Π= SG3

Input the SG1 (f = 2 MHz, V = 0.9 Vp-p) to the

SIN and measure the amplitude of the

AGCOUT.

(GAIN SEL) = 7, (AGC GAIN) = 255

 = SG2, Π= SG3

Input the SG1 (f = 2 MHz, V = 50 mVp-p) to the

SIN and measure the amplitude of the AGCOUT.
