EEVblog #803 – HP1740A Analog Oscilloscope
Dave saved this classic from the dumpster, a HP 1740A 100MHz dual channel analog oscillocope from the mid 1970’s.
It wasn’t supposed to be working so this is a look at the problem, a mini teardown, and some basic PSU troubleshooting.
Update: Even after 4 hours it still doesn’t fail with the covers off. So likely to be some sort of thermal issue as suspected.

Acknowledgments
The 1740A design group was led by Stan Lang until the start of pilot production when he transferred to another project. The design team included Jim Garner, mechanical design including the vertical attenuator switch, Eldon Cornish, who designed the horizontal section, and Van Harrison who designed the CRT circuits, power supplies, and gate amplifier.

EEVblog #879 – R&S HMO1202 Scope Bandwidth Hack Investigation
Dave investigates how the front end bandwidth limiting works on the Rohde & Schwarz HMO1202 series oscilloscope.
Is the bandwidth limit set just by the LMH6518 front end Variable Gain Amplifier chip through the SPI bus?
See the extended 50 minute version HERE that has much more detail and mucking around trying to get the R&S HMO1202 to probe itself.
