I’d bet on the tantalum, they are notorious. Regards, Stephen Hanselman Datagate Systems, LLC 3107 North Deer Run Road #24 Carson City, Nevada, 89701 (775) 882-5117 office (775) 720-6020 mobile

Hi all, I am lucky enough to have been able to visit SurplusGizmos this morning, where I found and purchased a 284 Pulse Generator. I am pleased, but wonder if anyone has advice regarding a first time

Hi All: Mostly the above seems to be ignored in this discussion... of course... it is a thread about 7000s. Just the same...and sort of on topic... if someone said to me slide over your 7404, with

Not in Califonia, but be aware that the MCP (microchannel CRT) in the 2467B has some things to think about. 1) while the bandwidth and brightness are very good, the MCP mechanism has a limited time

Mine is a model 3, with a bay for a TM504 below it. It's proudly labeled "NASA property". I don't plan on removing the sticker. It does fit the 7000 series and has the clamp for the feet. Harvey

dear members, I am from india ( just getting started into electronics as a hobbyist ) and my friend (who stays at sf bay region california) has got me a Tektronix 2467b oscilloscope (he had got a good

Hi Dave: We/I have to see a picture of that. Scopemobiles are great for say for the likes of a 465 or a 2415... but a fully stuffed 7704? Not saying it can't be done... but, can it be done for the

Something I just wanted to point out-? The cart doesn't need to be designed for the 7K series; I have one of my 7704As on a K212 scopemobile, which I think was designed for the 24xx series.? It

It's under Time & Date sub menu in the utility menu at the top of the menu. My personal guess is it ran for 4+ years 24 x 7 and was then replaced by a newer instrument in a mission critical

Thanks! I found one of the original shafts, so I might try the heat-shrink solution next. Two more questions before I break out the service manual and verify the voltages: - The graticule illium knob

Yeah, I've experienced the "grow to overflow the space" already. I'm sure I will expand to fill any space I get. My main focus is RF (the comparatively light weight of the 7904A relative to my HP 8566

Hi Dennis, Keep in mind that the 7904A timebase is not be calibrated at 200 ps/div (see the note on the front panel above the trigger source controls). The 7B15 is really intended for use in the 7104

Ah, now, based on my lab: 1) PC board fabrication, about 5 feet by 2 feet. 2) DC calibration (one rack and desk space) 3) RF work, maybe the same 4) Digital (main focus), about 4 feet worth of space)

All, I just wanted to wrap up and let you know where this ended up. My last post I was fighting an issue with the -15v rail. Now, when I started working on this scope, the -15 was fine. Sometime

Hi Sean, OK, I looked at the pictures. The third picture really caught my attention!!! My first reaction was "This is not possible". The bandwidth must be so far down at 2GHz that you would barely get

I think that offset-feedback loop is not affected by lack of sampling, so offset control is still functional (just as the input signal were always zero). Feedback signal enters the head at pins 2&B,

Hi Sean, Congratulations on capturing a 7904A - it is an astounding instrument. It was nice of John Griessen to offer you one of his scopes. Most of the scope carts that are wide enough for a four

One can also find three-shelf heavy-duty plastic carts that work well as ‘scope carts. I have one made by Rubbermaid on which I kept a Tektronix 575 for many years. DaveD Sent from a small flat

Sean, Good choice. The Tektronix model 204-2 ‘scope cart is made specifically for the 7000-series ‘scopes. It has five slots that hold spare plug-ins as well as a drawer that may be used to hold

Hi Reginald, How did you find out the operating hours and power up figures? I have an 11403A and there is nothing in the Utility Menus that would give me that kind of information. Just a wild guess
