LeCroy LA354 500 Mhz+ Color Analog Oscilloscope
The LA-354 is a 4 channel color LCD display, analog storage oscilloscope. This High-end analog oscilloscope for the digital age has a conservatively rated 500Mhz band width. In the photos below the scope is shown displaying a 1 KHz, 600Mhz and "YES" - it will trigger to around 900mhz with some attenuation. This scope has variable persistence in a choice of colors which is exceptional for glitch capture and single event viewing. It has a full set range of cursor measurements and built in frequency counter.
