The BW limit switch is off. Turning it on increases the rise time and smoothed the trace like I would expect. verify the setup. Yes but i checked the setup with my 468 (100 mhz) and the rise time was

With curves like this /g/TekScopes/photo/59361/1?p=Name,,,20,1,0,0 I wouldn't even bother to calculate a rise time. Obviously the main problem is roll-off. I would search the manual

Hey Ron Nice to get to know you! Thanks for telling us your story. I understand your dilemma with your wife - we all empathize, even if we won't admit it as candidly as you did ;-) I had no intention

Bit odd you bring this up now when I just got through posting in a thread about 2 sided boards, and that went into some other things. My experience, someone else about car radios using the same

So BW = 0.35/risetime in seconds or 0.35/0.000000006 = ~~60 MHz. The 465 should go around 100 MHz bandwidth. Around 3.5 ns. Is the bandwidth limit turned on ( maybe a fault with the switching? ). Do

You got a 9090DB ? Wow, well I guess you don't have to save money for a rainy day, those t hings go for some bucks. And for good reason. I may have been mistaken about the Marantz, I specifically

Time div is set to .05us but I have 10x mag on so that should be 5ns.

Ok, it looked like a probe at first. What is the H sweep rate set to? Can't see it in the pictures. Looks like 1 1/4 divisions on the horizontal 10-90% points. Regards

Clutter ? You gotta see this place. We moved out of 3 houses. Anyway, I got a couple pictures uploaded here you could look at. It's on AC so I didn't have all day, and my camera batteries are lunch to

You are looking at the waveform with a scope probe that presents a 10 meg ohm load to the pulse generator. What you need to do is use a 50 ohm cable to go from the generator to the scope input and

Regarding ripple current specifications, I have designed a high ripple application, indeed it is akin to KHz frequency spot welding given the currents pulsing to 800A or so. I have found that the

This may not be exactly what you think. Rise time is measured from 10% to 90%. I'd have to look at the manual for that scope, but I remember that the dotted lines on the graticule are supposed to

One of them, Mouser or Digikey, will ship for free or at a reduced rate if you place your order by mail with a check. This is useful if one needs a small number of parts. DaveD Sent from a small flat

Hey guys. I have done a lot of work to this 465. I had initially planned on selling it to help me buy some plugins for my 7633. I decided I don't want to sell it and am keeping it. Today I checked its

To avoid blanket statements: I've found that some Mouser prices are cheaper than Digikey prices. I've also found that Mouser does not carry some parts that I need (they went Altera rather than Xilinx,

About Digikey (Canada). They are FAST: Once I had parts in hand about 12 hours after ordering on the web. Next day is usual. For me they also have much cheaper shipping than Mouser. --Toby

Menahem, You may address me as Ron, or Mac (for machineguy).? I usually use Mac on the net and Ron in the "real world".? As a brief introduction, I am 78 years old, retired electronics engineer, now
