PC-Based USB Oscilloscope 2Channels 60MHz 200MSa/s FFT Analyzer ISDS220A

Introduction:
ISDS220A/ISDS220B dual-channel digital oscilloscope, is a product taken "low-cost, high-performance" as the design goals and it is well-designed bandwidth  60M, 200M sampling rate, 2 channels, supporting alternately X,alternating Y and XY mode  dual-channel virtual oscilloscope, spectrum analyzer, and has a 1KHz reference square wave output interface. ISDS220B device supports DDS and scanner functions. Of which there are five kinds of DDS output wave form ,sine wave the highest possible output 20M. Devices communicate with a PC via high speed USB2.0.

Features:
1. Streamlined design, compact size, USB2.0 interface, no external power source.
2. More suitable for notebook computer, used easily on business.
3. A small size (mm): 150 (L) x100 (W) x30 (H), easy to carry.
4. High refresh rate, high sampling rate, 200MS / s real-time sampling.
5. The software supports: Windows XP (SP3), Win7 (32 bit), Win7 (64-bit).
6. Waveforms: add, subtract, multiply, X-Y display.
7. The waveform data can be  output to EXCEL, BMP, OSC by time and voltage.
8. FFT spectrum analysis.
9. Full-function signal generator, and supports adjustable voltage amplitude and offset.
10. A computer can connect many DSO.
11. Secondary development library that provides an example of VC development.
