What is the source of the signal being displayed ? What kind of probe is being used ?Is it compensated ??Is the probe ground lead connected ? Do yourself a favor & lose the probe.Connect to a decent

Hi Ron, I wonder if we may know each other. I knew a Ron who would be about your age who ran an engineering organization in Cedar Rapids. At the time, I was a brash young engineering group manager in

Sorry Raymond, again I missed you message of a few minutes ago! BTW I sold my one and only 465 some time ago, so I can't help with doing measurements. Albert

They share the same output amplifier.

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
