IKA Logic's SCANALOGIC-2 PRO is a small, powerful 4-channel logic analyser with features not found elsewhere on a device this affordable.
April 2012 Update: ScanaStudio! Ikalogic has been working hard with this new release of their ScanaStudio Logic software. It looks like a substantial improvement, complete with new CAN and LIN and manchester decoders.
So you've got a soldering iron, decent multimeter, and a handful of good tools. An oscilloscope is on the horizon, but you want to see that I2C communication channel that's giving you grief now. Even if you did have your oscilloscope, would it decode that communication for you?
Fortunately, Logic Analysers are dedicated to showing you how different channels of communication look, and the better ones make it easy to see the actual data streams. The IKA Logic Scanalogic-2 Pro is such a device, and it's quite affordable too! Before you buy, download and try the software!
Here's a short list of what this handy USB-based device offers:
There's more to see, but these are the key features we've found noteworthy while playing with it. It's a cool little device.
Comparing it to the Saleae unit (which we also carry), there's some overlap and differences:
|Max Samples / sec||20M||24M|
|Protocols decoded||UART (Serial), SPI, I2C, 1Wire, Maplebus||UART (Serial), SPI, I2C, 1Wire,CAN|
|Acquisition time||Slower to upload to PC than Saleae unit||FAST sample-to-PC transfer|
|Data display||Must "Decode" to have data display onscreen||Auto-displays data|
|Cursors||Persistence, defined with click/drag||
Dynamically "pops" around with pointer
In short, the Saleae unit is more polished, having 8 channels and quicker/slicker software. On the other hand, the IKALogic supports FFT, can generate/playback serial & datastreams, and is less expensive.
Which is best for you? Umm... you can download and test the software of each, but for us, it's a bit of a toss-up. We're using both pretty much equally, as it's rare we need to watch more than 4 channels at a time.
