Dave Daniel.. the fastest 7000 series scope I have is 100Mhz.

Hmmmm... I'm going to check the attenuator modules in my flaky 7A26, 7A22, and 7S12.  If all else fails, I can bring them into work, where we have higher power microscopes. Say, anybody have 7000

Thank you for the 2213A reply! As far as I know, all of the aluminum electrolytic capacitor are suspect, as well as the the X2 and Y2 film capacitors that see the input AC. Replacing the small 10uF to

It looks as if it were meant for a 500 series scope. The PG506 (amplitude) does the standard 1-2-5 sequence that Tektronix likes, and will work in a TM500 series frame. The TM501 is effectively a

What is the fastest 7xxx ‘scope that you have? Sent from a small flat thingy

So, circling back here, am I better off with an external calibration device to service multiple scopes? For example, right now, I have four 7000 series mainframes (one of which is the military grade

Is there anyone here who, like me is interested in building this kit? I am sorry to say, I was slow on the uptake and missed out on Dutch's kit, but I look forward to anything he offers to help me

Yes I would think this should apply to the 2213, 2215, 2235, 2236 scopes, maybe even some others in the 22xx range.

Hello unnamed contributor: Thanks for your post. I have a 2215 scope and from. Your last comment I assume that what you tell about would apply to my scope as well. Is that right? Thanks again for

I bought this 2213A on ebay due to needing a quick solution low cost scope for some immediate work I needed to get done without using one of my regular bench scopes. In general it mostly needed

I added the optional USB parts, as well, which makes it easy to plug in a USB cable with just a standard USB charger to power it. Highly recommend it. The parts are cheap on Mouser and the SMD

Mine is still underway, but in preparation I installed the AVR suite, and after some path- and location adjustments the V4.0 firmware compiles. I hoped to learn some coding tricks from it, but after

Just s short note to say I received my clock yesterday and built it immediately (some new year resolution or other maybe). I'm very happy with the result, so a big thank you. David Partridge

Check the NPN transistor array on the fan board. I think it is component number U1690, and it s a common part like an ordinary MPQ2221A. All four transistors in the array are used, and one can go 

To all of you that may be interested, Part 1 of my articles on rebuilding the Siemen's fan motor #1AD3001-0A is up on my friends

Hi Mark, Did you find the cause yet? Sounds to me like a bad solder joint. I would replace the resistors in question and resolder the other joints and go from there. Robert

I am sorely tempted, but I have too many projects right now and I have to downsize in the near future as well. Looks like a 1A4 plugin in it as well. If someone is interested, I could pick it up and

Jim I spend way to many hours hours checking out the trigger components until I noticed the main line going into the trigger IC appeared to be quite thin so I checked the trace and found it was open.

Ho Roy, It's not as fast as the 547, probably more like a storage version of the 545. I used one for a while until I found a 547. It's a great performer but can have the HV transformer thermal

Paul, I guess there is no premium for all the dust! (Seems to me that 20 minutes with windex and paper towels and a toothbrush would make it way more attractive!) I wonder if the 549 is the storage
