Having just used a Saleae Logic 4, I know it'll do what I need. I know there are clones and there are options like the Logic Pirate. I need to record 30+ seconds of RS232 to look at the bit timing which is either 8.32 microseconds or 8.8 microseconds in previous tests.</div></div><div><br></div><div>Does anyone have any recommendations for a logic analyse that will allow me to record for up to a minute at 20MHz or higher?</div><div><br></div><div>Background... I'm diagnosing a device that runs Async at 115200, or at least is it supposed to. I is actually running at 120192 because the virtual UART isn't initialized correctly. That's 4.3% on a spec tolerance of 3.3% max. As is always the case, the vendor had more questions after I submitted the test results, so I need to run more tests.</div><div><br></div><div>Thanks,</div><div><br></div><div>Mike</div></div>
