By using the USB bus, the USBee SX digital test pod transforms a PC into a high-performance digital logic analyzer or signal generator that can store enough samples to fill available PC memory. It captures or generates hundred-million-sample waveforms, opening the door for previously unaffordable control and analysis applications for embedded developers. The logic-analyzer module that runs the USB SX includes an I2C, serial peripheral interface, and asynchronous serial bus decoder. The pod captures and generates samples up to 24 Msamples/s. An Auto Calibration feature automatically reduces the sampling rate for accurate and reliable timing. Price is $295.
