Paul Some options for consideration, not all meeting your specific requirement

The Siglent is much more responsive and rather less clunky to drive. https://digilent.com/shop/digital-discovery-portable-usb-logic-analyzer-and-digital-pattern-generator/ 32 ch at 200 MS/s and pleasantly inexpensive If I was buying, I would consider trying one Martin From: Paul Koning via cctalk [mailto:cctalk@classiccmp.org] Sent: 14 March 2023 01:13 Gents, I've been doing logic debugging (on a fairly primitive software defined radio I designed back in 1999) with an old Philips logic analyzer. It's not bad, certainly fast enough (I need 100 Msamples/s, it can do twice that) and it's more than wide enough (I need 32 channels). But its capture memory is microscopic so I struggle to see more than one or two transactions, and I need to see more than that. Some poking around shows various USB-connected logic analyzers for quite low prices, and a number of them seem to have suitable specs. I also ran across sigrok.org which seems to be an open source logic analysis framework that can drive a bunch of those devices. Nice given that too many of them only come with Windows software. I suspect there are others that have not too expensive logic analyzers and might be able to offer up suggestions or product reviews. paul
