Rigol’s DS4022 200MHz 2-channel Digital Oscilloscope competes head-to-head with other more expensive “famous brand” 2-channel scopes, but at a better price to fit your budget!  It incorporates Rigol's patented advanced UltraVision technology for a really fast refresh rate of 110,000 wfms/s. 

Sampling at up to 4GSa/s, the DS4022 design, with its huge 9” display, includes an amazing 140Mpts of sample memory (maybe the largest available on any oscilloscope anywhere?)  Drilling down into long data streams for elusive, tiny glitches is made much easier when you can scroll through this huge memory! Rigol Technologies’ DS4022 is ideal for a wide variety of uses: education, R&D, communications, defense, aerospace, QC, and industrial electronics.  Two RP3500 500MHz probes are included in the package.
