The Signal Generator software that runs on your PC and controls the USBee ZX Digital Test Pod is a powerful addition to any design and debugging development.

zxsg1

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

The USBee ZX 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.

 (*) Maximum sample rate depends on your PC hardware CPU speed and USB 2.0 bus utilization.  For the fastest possible sample rates, follow  these simple steps:

  • disconnect all other USB devices not needed from the PC
  • Do not run other applications while capturing or generating samples.
  • Use a USB2.0 High Speed enabled port
