Or I wasn't clear about what it was. I have a 5440 and a 5103N, both of them, on the bottom, have a blue U shaped piece of plastic likely meant to grab onto the mounting latch for a scope cart.

Hello, Harvey-- Thank you for your suggestion. I couldn't locate a "rail catch" on the 5403, so I suspect that the two mechanical designs are significantly different. I noted that the scope's two

Fabio: 1. trace backwards: check that someone hasn't plugged up either P51 or P501 backwards: they're both 4 way strips so possible to get them the wrong way around? 2. Short scan: you've got

Hi Brad, Artekmanuals.com has the operating and service manual for the 5403. I've never seen it, but it will probably be very nice for not much money. tom jobe... PS The Tektronix 5403 is a very nice

Bad luck on that try.  If you log onto groups.io, go to the TekScopes file area and sort the list by uploaded date you will see about 12 files uploaded since Jan 1st.  Maybe not everyone who uploads

I'll put a copy of the J16 datasheet up on the files area which includes the list of application notes.  A lot of the J16's have gone to industrial recyclers (see ebay) and the paperwork gets thrown

Terrell I don't know you, and you don't know me. It is astoundingly arrogant and disrespectful of you to lecture me, with overwhelming self-presumptuousness that you are correct. "You've never seen

Yes and no. If you use the usual scope plugins, then the accuracy of a 7000 series scope is as good as any other scope. You're still trying to read a spot on a screen. If you use the digital

I just opened up a 5440 scope. Remove the bottom cover. If there's a rail catch on it, then that needs to come off too. The power supply watch points are forward on the board, assuming it's the

Hi Ralph, Given that the accuracy of an oscilloscope isn't that great for voltages in particular, I'd have to say you are set up more closely than many folks out there. Most analogue oscilloscopes

Thanks for the responses. Gives me a better idea what to expect when scope is repaired. Variable persistence sounds great. Those two links to the Tektronix magazine articles was rich in

Hello-- Before I attempt anything really stupid (*) <g>, can anyone point me to instructions for gaining access to the power supply board in a Tek5403 scope? Also, does a power-supply schematic

I have the names of the Tek J16 photometer and radiometer Application Notes. I am unable to find any of them in printed form. Very odd that these useful technical articles should essentially

I have seen that Pyramid Generator before. Looks very interesting. One on the bay for $200

Rats! An addendum; I forgot about the system's tendency to truncate a URL or e-mail address. In my prior message, that should read; REED714 (at) sbcglobal (dot) net Enjoy, and 73;

Good morning, gentlemen; Calibration. What a subject to discuss. A few of things: (1.) I have Leo Bodnar's device. It has proven useful. When propagation has been relatively stable, a

Walter: Would be interested in an HP 11707A plug in for the 8660 generators if you have one in stock. I need it to debug an 8660D.. Thanks ed
