Chuck, Since this whole thread on the Guernsey Island 2445 has that (correct) spelling as its title, I wouldn't have thought it would be so hard. I am only being a bit grumpy, not really fuming mad.

Speaking only from experience with TDS 540x, yes the calibration is kept on the acquisition PCA. I think, but have not taken the time to prove, that the primary use of the NVRAM is to store trace

Steve, If you are hesitant to use eBay you can buy a NOS tube from Antique Electronics Supply. They currently list a 5V4GA for $29.90 at

Tektronix called its factory in Heerenveen, The Netherlands, "Tektronix Holland" Why should I differ? Calling it "Holland", for short, when I am writing about Tektronix factories, simplifies my

I ran across two cables, about 3.5 feet long. BNC on one end and what looks like a push-on SMA on the other. Marked Tektronix 010-164 and P6041 Zo=50 ohm. No need for them, will swap them off for a

Sorry, it's claimed. I promise next time to list things just like they were going in test equip for sale, with location, condition, price, payment methods... I just thought this one was not going to

What country is it in? What are you asking for it?

It's my understanding that the calibration constants are stored in EEPROM on the acquisition board. There's no reason to worry about the options, as it's easy enough to restore those with GPIB or

I'll probably think of it right after I hit "send", but what does SPC stand for in this context? Steve Hendrix

Hi Steve, Make sure that it passes SPC from the utility menu - at least 10 times with no failures. Also run the full self test from the same utility menu. Jay

Steve- Looking at the schematic I downloaded for the 514, there are five capacitors in the power supply that are two section 20 micro-farad cans, and these all should be tested, reformed, or

Hi Steve, You need to be concerned with the NVRAM chips - DS1486 clock chip and the DS1650/DS1250. They have internal batteries that hold the calibration constants and options info. The batteries

Chuck, speaking as a Brit, can you please stop spelling it "Gurnsey". I don't think you would like it much if I referred to the US city as "Filadelfia" would you? I should maybe point out that in UK

I didn't research this as well as I might have, because I really didn't expect to get it. I made a fairly low offer on eBay for a TDS784C, fully expecting it to be rejected. Pleasant surprise when it

If you completely remove the cap (I usually do), a copper tubing cutter works wonderfully.... One of these things: https://www.harborfreight.com/tubing-cutter-40913.html (Yeah, I know, Harbor

Does anyone in the group have any spares for the AWG2005/2020/2021/2041 Series Waveform Generators? Specifically: Low Voltage Power Supply 620-0058-02 or 620-0065-00 Or FPP Board (A7) Option
