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.
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
