It's so cute that Bob didn't understand Teflon is a dielectric. A metal coat hanger would have been better. I bet Bob told the engineers to use a Teflon rod. Notice he says that they solved the problem.

Absolutely Love these videos and Bob Pease, but I'm skeptical about detecting individual cosmic rays with a charge amp. I've played with femto-amp parts like LMP7721 in various well guarded and shielded situations and never noticed even the slightest susceptibility to radiation, except for the low frequency "ion chamber" leakage effect due to intense fluxes from radioactive sources. Would be cool though....

11:54 Ha! I thought this was early to mid-90's based on the video quality/style/set/clothes, especially with the floppy drive visible on the scope. I was thinking, "Wow, Tek was way ahead of the curve. That FG's GUI looks a lot like the modern post-beige era standard." Then these timestamps show up for December 2005. Is it just me or is Mr. Peasy - Dr. Cheesy :-)

I enjoyed the Agilent plug. I would love a 54642D scope, but they're still a bit pricey (~$1000 USD) and they only have two analog channels. My friend picked up a lower-end 54622D for $100, which has the same user interface but only samples at 200 MSa/s, which isn't fast enough for all of my work. The newer MSO6000 series has four channels and greater bandwidth and sample rate, but they have kept their value very well and are even further out of my budget, at $5000+ for a model with fair specs.
@humgar 5 жыл бұрын
I love the 54600 series. The design is very intuitive and it's usually problem free. 54640 series is a different beast that has a quirk that the ADC runs too hot and the hybrid will eventually fail if there is not a custom fan blowing at it directly. It's worth around $3.8k so if you can get it at $1k, it's a steal. Chances are recyclers are willing to sell it to you at that price but you are on your own once the 30 or 60 days is over. You can do the fan mod yourself with the instructions here: wonghoi.humgar.com/blog/2016/07/24/agilent-54641d-fan-mod/

@@humgar just picked up an 54642D with complete probes and SMD clips for 350€. 3.8k is a joke...I mean Keysight official Ebay shop will sell you a 1Ghz 4ch 3000X for around 6k, so charging more than half of that for a 20 year old unit with just 2 ch and CRT is ridiculous.

@petruha69 5 жыл бұрын
Donato Greco, the type of a current source you're proposing would be totally dependent on the transistor's beta. Good luck making it a repeatable and a stable design. Sorry dude, Bob's schematic is a true and tried classics.
