There are more powerful, EXPENSIVE tools, but we're sure you'll find the Saleae Logic Analyzer to be a convenient, capable, price-effective!

Additional Information [Hide]

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:

  • 8 Inputs
  • Voltage Range: -0.5 to 5.25V
  • Input Low Voltage: -0.5 to 0.8V
  • Input High Voltage: 2 to 5.25V
  • ESD and over-voltage protection
  • Logic threshold not adjustable
  • 24MHz Maximum Sample Rate
  • 200M+ samples, absolute limit depends on system RAM

Included Equipment:

  • Saleae Logic Module
  • 9x1 Ultra-Flexible Test Lead Set
  • x9 E-Z-Hook XKM Micro-Hook
  • USB 2.0 Cable (5')
  • Soft Case

Device parameters:

  • Power requirement: Less than 1W (from USB)
  • Size: 1.62" x 1.62" x .32"
  • Mass: 22g (.78 oz)

System Requirements:

  • Windows XP, Vista or 7
  • Vista 64-bit or 7 64-bit
  • 1 GB or More RAM
  • 1.5 GHz or Faster CPU
  • USB 2.0 Port
  • High-Speed Internet Connection (for Software Download)

Comparing it to the IKALogic Scanalogic-2 Pro unit (which we also carry), there's some overlap and differences:

  IKALogic Scanalogic-2 Saleae Logic
Channels 4 8
Max Samples / sec 20M 24M
Microhooks Adequate Deluxe!
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

OS WIn32 Win32/WIn64/OSX/ Linux32/Linux64

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.
