PC USB Logic Analyzer - Who Has The Best Software? Make this no affordable LA. I'm sure Agilent can sell you a box that can do this. Well, the 10k€ Agilent desktop LA on my bench at work can't do this, neither can the 14k€ LeCroy Waverunner Scope with the ~1k€ SPI plugin. Well, the latter can trigger on SPI patterns, but of course only one the sample memory. So it actually already triggered and just filters the memory as described above.So I'm not really convinced that there is any device on the market that can combine protocol and timing trigger in realtime.
Of course you could let someone design you a specialized LA or do it yourself, but I doubt that there is an existing solution yet. Actually, I think it should be pretty easy to add e.g. an SPI decoder to an FPGA LA design, but then you'd need a larger FPGA and to change the protocol, you'd need to download a new FPGA bitstream. Would the OLS come close if they ever finish the software side of the demon core? I agree, this is a missed opportunity.
Or they just use a bigger FPGA. Soundcard Scope. Soundcard Oscilloscope deutsche Version Author: Christian Zeitnitz Main features: The PC based Soundcard Oscilloscope receives its data from the Soundcard with 44.1kHz and 16 Bit resolution. The data source can be selected in the Windows mixer (Microphone, Line-In or Wave). The frequency range depends on the sound card, but 20-20000Hz should be possible with all modern cards. The oscilloscope contains in addition a signal generator for 2 channels for Sine, Square, Triangular and Sawtooth wave forms in the frequency range from 0 to 20kHz.

Signal Sources The signals for the oscilloscope can be internal to the computer (MP3 player, function generator etc.) or from external sources (line-in, microphone).
