The vertical output Amp and some other parts, like parts of the channel switch, are common. Raymond

You have the proper fast rise generator to perform an adjustment. The risk in my opinion is that you destroy a stuck trimcap or trimpot. You might first verify DC levels in the output amplifier stages

I would think that it's the moderator's responsibility and no one else (elders or otherwise) to filter the various threads. There are certain topics that are completely off topic like politics and

Before you start turning screws: 1. It is not uncommon for the variable caps to become open. I've had that happen to some in the vertical (output) amplifier. I've seen both the rotor not moving *and*

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

Im using a 50ohm cable with a 50ohm through terminator. /g/TekScopes/photo/59361/2?p=Name,,,20,1,0,0

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
