CRO, Square wave generator & Frequency counter

The voltage at the analog inputs can be continuosly captured and displayed to make Phoenix behave like a low frequency CRO. The sampling rate is restricted to 100 KHz due to the conversion time of the ADC. The following screeshot shows Phoenix displaying a 152.4 Hz squarewave, generated on the PWG socket, fed to CH1 directly and to CH0 after an RC integrating circuit.
