V10. V11 Black noise threshold level and clamp voltage
……
[VBTH, VBCL]
(1) Apply DC voltage to the external AGC, IF AGC (pin 17) and vary it.
(2) fp = 45.75MHz 15kHz 78% AM10mVrms (VIF input)
(3) Adjust the IF AGC (pin 17) voltage to operate the noise canceller.
Measure the VBTH, VBCL at test point A.
