10 Channels multiplexed between the Logic Analyzer and as general purpose IO
3.3V CMOS logic
7 mA source and 12 mA sink when used as GPIO ()
Logic Analyzer has a sample rate of 10 MS/s ()
Maximum buffer size of 32640 samples per channel for the logic analyzer
OpenScope MZ has two DC outputs that are driven by their own PWM output with a single PWM line for the DC offset. A gain circuit is
implmented on the OpenScope MZ to provide a voltage range of -4 V to 4 V for each channel. A feedback circuit is also present to allow
for calibration of the DC output.
