USBee SX Features

The USBee SX Digital Test Pod combines state of the art design with easy to use PC software to give you a complete digital test bench in a small and affordable package. Connecting to your PC, the USBee SX Digital Test Pod uses the power and speed of the USB 2.0 High-Speed bus to capture and control information from your own hardware designs.

The USBee SX runs three different applications:

USBee Suite

Works with the USBee Suite Logic Analyzer Software

Easy to use Logic Analyzer / Oscilloscope

The USBee Suite is powerful electronic signal analysis software for your USBee Test Pod.  It starts out as an easy to use Logic Analyzer and Oscilloscope and adds serial bus decoding and world class configurability that lets you solve your electronic problems quickly!  Some of the serial busses that are decoded include: I2C, SPI, Async, USB, CAN, 1-Wire, PS/2, SMBus, I2S, Sync Serial and even your own Custom Busses.

World-Class User Interface

You look at a Logic Analyzer / Oscilloscope for extended lengths of time.  Why don't you make sure you can enjoy it at the same time?  The USBee Suite software lets you choose the look and feel of the interface and saves that information for when you come back to it again.

Best of all the USBee Suite Standard is Free!

The USBee Suite Standard is a free download and will run in Demo mode without a USBee, or on any USBee SX, USBee ZX, USBee AX-Standard, USBee AX-Plus, USBee AX-Pro, or USBee DX Test Pod.  So take it for a spin.  If it has been a while since you've used your USBee, pull it out of your pocket and experience the power of the USBee Suite.  

Upgrade to the USBee Suite Pro for State-of-the-Art Debugging Features!

The USBee Suite Pro builds upon the rich features set of the Standard version and adds high powered capabilities such as the PacketPresenter custom packet decoder, Smart Markers, enhanced PacketPresenter API for developers, annotation capabilites, enhanced acquisition control for repeated measurements, display control, analog channel scaling, analog bus decoding, and enhanced file importing and exporting.

The USBee SX is a complete digital test bench in one compact and easy to use pod. Combined with the free, yet powerful, Windows® 7, Vista, XP and 2000 software the USBee SX is a deep buffer depth Logic Analyzer and Signal Generator.  Included in the Logic Analyzer module is a High Speed Asynchronous Serial bus decoder, SPI Bus decoder and I2C bus decoder.  The USBee SX comes with a 6 ft USB cable, highly flexible test leads and top quality test clips - everything you need to start debugging your design with your computer.

USBee SX takes advantage of already existing PC resources. The USBee SX pod streams data over the High-Speed USB bus to and from the PC, allowing the PC to perform all of the triggering and data storing. This makes possible an affordable USBee SX, while pushing the sample storage capabilities orders of magnitudes beyond that of traditional dedicated logic analyzers or signal generators. The USBee SX Digital Test Pod can utilize available PC memory as the sample buffer, allowing selectable sample depths from one to many hundreds of millions of samples.

Logic Analyzer Features

The USBee SX also comes with the original Logic Analyzer software shown below.

usbee-sx logic analyzer

The PC based Logic Analyzer software provides the following functions:

  • Tiny USBee Pod (2" x 1.5" x 0.5") connects to your hardware
  • Logic Analyzer software runs on your PC
  • USB 2.0 High-Speed connects the pod to your PC
  • Sample Rates (1Msps up to 24Msps) - max rate dependent on your PC
  • 8 channels
  • Sample Depth of 1 million samples up to available PC memory
  • Sample Clock Output or Input
  • 4 configurable Trigger states using any of the 8 signals
  • Waveform display (above)
  • Listing display
  • I2C, Async, SPI Bus Decoder
  • Save, Open and Print captured data and settings
  • Movable cursors for easy measurements
  • Output files can be loading into Signal Generator to "playback" the capture

The Bus Decoders are included in the Logic Analyzer application and extract the bus traffic bytes from your captured waveforms making debug of your circuit fast and easy.

Bus Decoders

high speed async bus decoder

 

High Speed ASYNC Bus Decoder

  • 1 to 12M baud in 1 baud steps
  • Output format in text file with ASCII, Hex or both
  • 8, N, 1 or 7, 1, 1
  • MSB or LSB first

The Async bus decoder is part of the Logic Analyzer.  You can access it through the View menu.  You first capture a trace of data that contains the Async bus signals.  Once you have the trace captured, you can then run the decoder to extract the data.  You can select any of the eight lines for the decode.  Once the decode button is pressed, the protocol and data is then extracted to the text box, where you can then select, copy and paste this data into any other program for formatting or processing.

usbee-sx spi bus decoder

SPI Bus Decoder

  • SPI Clock up to 12MHz
  • Output format in text file with ASCII, Hex or both
  • MSB or LSB first
  • Selectable clock edge sampling

The SPI bus decoder is part of the Logic Analyzer application.  You can access it through the View menu.  

You first must capture a trace of data that contains the SPI bus signals, SS, SCK, SI and SO.  Once you have the trace captured, you can then run the decoder to extract the data.  You can select any of the eight lines for the four protocol lines.  You can specify which edge the data lines are to be sampled on (opposite of the data changing edge.  You can also choose the output data format and how many bytes to write out per line.  

The protocol and data is then extracted to the text box.  You can then select, copy and paste this data into any other program for formatting or processing.

usbee-sx i2c bus decoder

I2C Bus Decoder

  • I2C Clock up to 12MHz
  • Output data includes Start, Stop, Ack and Nak as well as the data

The I2C bus decoder is part of the Logic Analyzer  application.  You can access it through the View menu.  

You first must capture a trace of data that contains the I2C bus signals, SDA and SCL.  The I2C bus is Open Collector, meaning that you must have an external pull-up resistor on each of the SDA and SCL lines.  You most likely already have one on your circuit design. Once you have the trace captured, you can then run the decoder to extract the data.  You can select any of the eight lines for the SDA or SCL lines.

The protocol and data is then extracted to the text box.  You can then select, copy and paste this data into any other program for formatting or processing.

Signal Generator Features

Included with the USBee SX is the Signal Generator software that lets you create digital waveforms using the USBee SX pod.

The Signal Generator software provides the following functions:

  • Tiny USBee Pod (2.1" x 1.3" x 0.5") connects to your hardware
  • USB 2.0 High Speed connects the pod to your PC
  • Signal Generator software runs on your PC
  • Generate Sample Rates (1Msps to 24Msps)
  • 8 channels
  • Sample Buffer: 1 million up to the available PC RAM (hundreds of millions)
  • Output Sample Clock
  • External Trigger Input
  • Waveform display lets you "Draw" the signals you want (above)
  • Save, Open and Print data and settings
  • Movable cursors for easy measurements
  • Can input files saved by the Logic Analyzer module to "playback" the capture

Perfect for your BASIC Stamp® and PIC® system debugging!

The USBee SX Digital Test Pod can capture and generate samples up to a maximum of 24 million samples per second depending on the PC configuration. The USBee SX Auto-Calibration feature automatically reduces the sample rate to ensure accurate and reliable timing, even on systems with slower processor and USB bus speeds.The USBee SX Digital Test Pod perfectly merged features and functions to provide exactly the performance needed for hardware and microprocessor designs such as BASIC Stamp and PIC systems to ensure an affordable and compact unit.

The USBee SX Digital Test Pod does not need an external power supply.  The USB bus supplies the power to the pod, so your PC will be supplying the power.  The Pod does, however, require a self powered hub (not bus powered) if a hub is used between the PC and Pod.

Each USBee SX Digital Test Pod package includes

  • USBee SX Universal Serial Bus Pod
  • Set of 11 multicolored test leads and high performance miniature test clips
  • Getting Started Guide
  • USB Cable (A to Mini-B)
