It can decode and trigger on a bunch of protocols and you can script your own decoders in JavaScript. For UART/SPI/I2C & CAN it has a UI for sending and receiving data and files over those buses, and some of them can also be scripted. It’s got client software for windows/mac/Linux, and even has Linux-ARM (ie raspberry pi) support. It’s the closest thing I have to a “swiss army knife” for embedded development.

Those can run standalone to capture data, and you can script it with Lua that runs device side. It can also do output as well as input, and it also has analog inputs and outputs. It’s a bit pricier at $450, but I think I paid $150 for mine by setting a search alert for it on ebay then using an auto-sniping tool to win the auction(after a few failed attempts to win one manually). </p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><div style='mso-element:para-border-div;border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal style='border:none;padding:0in'><b>From: </b><a href="mailto:triembed@triembed.org">Brian via TriEmbed</a><br><b>Sent: </b>Monday, February 22, 2021 9:14 AM<br><b>To: </b><a href="mailto:triembed@triembed.org">triembed@triembed.org</a><br><b>Subject: </b>Re: [TriEmbed] MSO may grow on you Re: Budget minded oscilloscope</p></div><p class=MsoNormal><o:p> </o:p></p></div></body></html>Realizing that it's not necessarily what one might put in the <br />"budget-friendly" range, I thought I'd plug both Pico Technology and <br />Saleae. I have a 4-channel USB DSO PicoScope (3000 series, ~$600-$2400 <br />depending on options) and a 16-channel logic analyzer from Saleae (an <br />older, now discontinued digital-only model). They both work very well, <br />plus both offer various levels of API/SDK availability if you're keen on <br />writing your own logging or analysis code.<br /><br />Saleae's current 16-channel analyzers are 50 MS/s MSOs, but the one I <br />have is not, so I can't speak to the quality of analog measurements. <br />The PicoScope 3000 series is 1 GS/s.<br /><br />PicoScope 3000-series scopes are available in MSO form.<br /><br />Both are USB devices that depend on a host PC for control and display.<br /><br />$0.02,<br />-Brian<br /><br />On 2/22/21 9:00 AM, John Vaughters via TriEmbed wrote:<br />> Pete,<br />> <br />> Which Rigol model do you own?<br />> <br />> I very much agree with you.
