A year ago, electrical engineer Mark Omo unveiled his 1 Square Inch 20Msps Oscilloscope designed around a PIC32MZ EF, which used its internal ADCs in an interleaved mode to gain that 20Msps. It even had an integrated 1-inch X 1-inch OLED screen for the readouts. Now he’s back once again with another oscilloscope project, the Probe-Scope, a self-contained 60MHz 250Msps oscilloscope and probe in cable form factor — meaning all the acquisition hardware is contained along the cable.
