HandyScope HS5: 200 MS/s 250MHz BW, 2 Channel, USB Digital Storage Oscilloscope, 20MHz AWG, Spectrum Analyzer, Voltmeter, Transient Recorder
HS5-220XM-W5
The Handyscope HS5 is the first USB oscilloscope (USB powered) sampling at 200 MHz, with a 14 bits resolution and a 250 MHz bandwidth. This makes it possible to analyze very fast signals with very small amplitudes. The smallest distortions can be revealed due to the high resolution and bandwidth. Because of the deep memory (up to 64 MSamples on one channel), long record measurements are available for intermittent phenomena and Fast Fourier Transform calculations with over 32 million spectral lines can be performed. Using very fast FFT algorithms, an FFT with 1 million spectral lines can be performed within a second.

Real Time DSP Software
ATS-GPU
ATS-GPU is a software framework developed by AlazarTech to allow users to do real-time signal processing using an Open CL compatible Graphical Processing Unit (GPU). Input to the GPU can either come from an AlazarTech PCI Express waveform digitizer or from user-supplied data. Fundamentally, ATS-GPU solves the problem of transferring data from a waveform digitizer to a GPU at very high speeds. A floating point FFT routine built into ATS-GPU has been benchmarked at 235,000 FFTs per second for 2048 points on one input. Ideal for Optical Coherence Tomography (SS-OCT). Benchmarks also showed that users can keep up with 500 MS/s sampling on one channel for 2048 point streaming FFTs.
