The MSO-28 is a USB-powered, entry-level, mixed-signal, 60MHz oscilloscope adapter for PCs. This lightweight, economical scope adapter combines a two-channel oscilloscope with a synchronous eight-channel logic analyzer, sampling at 200 MSa/s (5 ns), in an all-in-one compact, extremely portable USB instrument. Simultaneously-clocked analog waveforms and digital data can be displayed in phase on the same screen with the efficient and easy-to-use FrontPanel software. The MSO-28's triggering options include: oscilloscope (analog) trigger: rising/falling edge and pulse width; logic analyzer trigger: 8 bit trigger word; SPI trigger (32-bit trigger word); I2C trigger (32-bit trigger word) or any of the logic lines. The 200MSa/s sample rate and 60MHz bandwidth allows capturing a 60MHz signal in single shot mode, or faster repetitive signals, with an effective repetitive sampling rate of 1GSa/s. The FFT Spectrum Analyzer shows frequency spectrum information up to 100MHz for analog input signals, and has controls for FFT window, FFT type, and FFT resolution. The software also supports averaging, memory and plot subtraction.
