Oscilloscope Agilent 54621A Megazoom 2ch 60MHz test repair teardown

this really nice Oscilloscope is from 2000, super fast controls, all mecanical encoders (needed cleaning) HP changed name to Agilent in 1999-2000 for their Test and Measurement type of product line, and this scope is one of the first products made, with the new Agilent name. So of course you see HP written on PCB and chips.
-3dB at 70MHz so it is actually a bit better then 60MHz as specified.
trigg and measure even up to 400Mhz, but of course level is very low.
video also show 4mHz YES MILI HZ !! sine wave measurement !! in the 50Sec/Div range.
you will also see where the MEGA-ZOOM name came from, wow it is impressive how you can zoom in a stored waveform memory. (the software contain Easter-Egg Astoroids game ROCK_ON file save)
Previous line of HP scopes contained TETRIS
