There are more powerful, EXPENSIVE tools, but we're sure you'll find the Saleae Logic Analyzer to be a convenient, capable, price-effective!
We've known about the Saleae Logic Analyzer for a while, but it was only when our intern Jerome brought his own into the office we found out how cool of a tool it really is.
This tidy little tool measures just under 42mm (1-3/4") square and jacks into your USB port. Connect the 9-line lead set (with plug-in micro-hook grabber-nabbers) to the analyzer, boot up the software, and get to debugging your data stream!
The software lets you configure the channel to detect the levels shifts in a human-readable manner. Debugging I2C? It will translate the datastream above the level shifts so you can read the actual stream without having to calculate the 8-bit ASCII values the data stream represents.
Watching RS232? It will display the data in Hex, Octal, Binary and Decimal. It also features optional auto bit-rate detection for those "Ummm... I don't know what I'm connecting to. 2400/n/8/1? Or is it 9600/e/7/2?" moments.
SPI interpretation makes it sooo much easier to work with. It clears up the confusion of SPI settings by displaying data in Hex, Octal, Binary, and Decimal.
The Saleae Logic even lets you set up the logic-condition to start capture by. Specify a "LOW/LOW/HIGH" as your trigger, and it will start recording as soon as that condition is met on your data stream!
Here's what it offers:
Comparing it to the IKALogic Scanalogic-2 Pro unit (which we also carry), there's some overlap and differences:
|IKALogic Scanalogic-2||Saleae Logic|
|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, quicker/slicker software and slicker serial-decoding functions.. On the other hand, the IKALogic supports FFT, can generate/playback serial & datastreams.
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, but the Saleae does natively support Linux, OSX and WIndows OS in both 32 and 64 bit flavors.
