Checking out a second-hand Saleae Logic (a 24 MS/s, 8 channel USB logic analyzer - that works on a Mac!!).
I recently had a Saleae Logic fall into my hands - it’s an old model and was looking for a good home.
It is similar to the current range of products, but lower specs:
- USB 2.0
- 24 MS/s
- 8 digital channels
I was a little curious, but didn’t expect much since it was a discontinued product, and I wasn’t even sure if I could find the right software to make it go.
While playing with the M62429 today, I thought “why not give the Logic a go”.
And I was very pleasantly surprised. Saleae have done a brilliant job of creating an excellent experience, and continuing to support their discontinued products.
I was up and running in about 30 seconds!
I think this device just went from being a curiosity to something I can see my self reaching for quite frequently.
This put a smile on my face … go to Saleae Downloads, and they have a good looking site that recognises me as a MacOSX user and offers to download Version 1.2.10 for Mac OSX 10.7 Lion+. If only more electronics equipment manufactururs would come to the multi-platform party!
The software installed like a “real” Mac app, and immediately recognised the old Logic when I plugged it into the USB. Here’s my first trace. Unfortunately not a standard I2C or SPI protocol so I’m not sure how well the protocol recognition/analysis works yet.
The USB device profile as it shows up on my machine:
