Regarding the to-be-defined handshaking, one of them will need to be to a microcontroller interrupt, so it could be used for the signal for indicating when the DAC output is about to be set to zero degrees of the sine output. For the overload circuitry, maybe an OR&#39;ing is enough into another single interrupt, i.e. the microcontroller can then try to enable the input attenuators, if it doesn&#39;t clear the issue then the microcontroller knows the source level needs adjustment.</p><p>Perhaps the overload could also be noticed from a harmonic, but it will be good to have the hardware method too.</p><img src="https://community.element14.com/aggbug?PostID=9705&AppID=18&AppType=Weblog&ContentType=0" width="1" height="1">
