Rigol’s DS4054 500MHz 4-channel Digital Oscilloscope is similar to more expensive 4-channel scopes from other leading brands, but at a lower price to better suit budget constraints we all face!  It incorporates Rigol's patented advanced UltraVision technology for a really low noise floor and a fast refresh rate of 110,000 wfms/s. 

Sampling at up to 4GSa/s, the DS4054 design, with its large 9” LCD and easy-to-use GUI, includes an amazing 140Mpts of sample memory - quite possibly the largest available on any bench-top oscilloscope.  Investigating data streams for infrequent tiny glitches is now made much simpler when scrolling through a huge 140Mpt memory!  Rigol Technologies DS4054 is a great tool for a wide variety of applications: education, R&D, communications, defense, aerospace, QC, and industrial electronics.  Four high quality RP3500 500MHz passive probes are included in the package.
