First Prize
MultiProtocol Logic Probe
(complete abstract)

When it comes to troubleshooting a circuit, the process of lugging a logic analyzer or oscilloscope around and then getting everything set up can be time-consuming and inconvenient. With only three buttons, the MultiProtocol Logic Probe provides multiple analyzer functions in a compact instrument that can be held like a large pen. At roughly 1.5² wide and 6² long, it can quickly probe and save hundreds of waveforms in its 512-KB memory. Using an FPGA in conjunction with the Z80S183 serial ports and analog inputs, the Probe can save digital or analog data and display it in logic analyzer form, serial protocol analyzer form (e.g., for RS-232), digital voltmeter, digital counter, or oscilloscope form (up to the 500-kHz sampling rate of the Z80S183). A unique FPGA digital sampling circuit permits 200-MHz logic level data acquisition from the probe tip. Additional connector pins allow an external clock, trigger, and 16 bits of sample probes to be attached to the MultiProtocol Logic Probe as needed. An optional serial computer interface is also provided.
