So this leaves the Macbook and Macbook Pro lines. If I was to create a system "from scratch" I'd definitely choose a laptop that is capable of running it so I don't have to worry about workarounds for older macOS versions.įor performance reasons I'd probably would not pick a Macbook Air. Let's work from the software side: The most current Logic version (10.6.3) requires as the OS 10.15.7 or newer, aka "Catalina" or "Big Sur". Purchased a hand held logic probe and this is also proved useful and I now have a logic probe I plug into the breadboard which I hope will perform well enough.Ĭheers again for the info link, very good article.Since you are asking for used/refurbished machines I assume you're on a budget here. Anyway I won't be buying a very expensive LA for my hobby fiddling about and I'll make this one work. Will try some experiments later when I get back to the workbench. However it may be, for the work I'll do, this won't be a problem.Įxternal triggering seems to be useful though as everything can happen so fast you may not capture what you are looking for or capture it and not be able to subsequently find it among the mass or collected data especially if you don't use a protocol that decodes it into something more readable. I understand now why a clocked signal capture could be really important if the capture rate isn't fast enough to resolve different logic state changes. Scroll down on this link to "External Clocks". The small signal you're seeing could be just the CLK picking up other signals on the PCB. I don't know if I can use it without the CLK feature - depends on what it does whether I will be able to utilise it in the future. I missed where that internal/external selection is. I don't know how to tell if any additions have been made for the CLK input. Mine doesn't look like anything like any of those clones on the inside. I tried Logic 1.1.15 and 1.2.1, but can't find an external clock option.
The second one shows a screendump of version 1.1.4. The first one tells to go to the saleae download page. In software the internal or external clock can be selected. The CLK input on other models can be used for the signal, but also without. It seems there is alternative software for it :Ĭould you open the case, to see if some additions are made for the CLK input ?
If they are, they put the Saleae brand name on a clone.
Some have +5V and GND, most have GND and GND.Ĭould you measure if that CLK is an really an input ?
