Fluorescent lamps are mercury vapor lamps, and mercury vapor, when ionized, emits predominantly blue and ultraviolet. The phosphors that coat the tube turn this high energy UV into visible light,

I searched a lot here on the group and found this topic that I believe has the same defect as my

Thank you for your help. I'll try to explain it better: When I bought the scope, when connecting it to 220V (voltage from the mains network) the Rifa capacitors exploded. That was 2 years ago. At

Leandro, did you do a complete calibration? What was the cal status before backup of NVRAM? Did you do a DC bal? Your description points to lack of CAL. Do you have the required CAL

Do a search for osibatteries tektronix 212.  $22.00 per pack.  their site is broken right at the moment I'm posting, but Google gave the $22.00 USD result. The 211 uses the same batteries as the

Dave, Since fluorescent lamps use mercury vapor to generate UV which then excites the phosphor lining the tube, they do produce some UV output as the phosphor absorbs and converts most of it. The IV

I have a number of 7000-series plug-ins of varying ages. The intensity of the colors (silk screened? anodized?) definitely varies, but not always "oldest are most faded". I suspect it has to do with

I can't add anything except that I thought those colors were too deep, but since the "tek" logo is blue, it's a later model.  My 7B15s are all pretty washed out, and my later 7104s are as well.  In

Will these perform the same as 067-0616-00? I have one of these 067-0616-00 that I plan to list on ebay eventually, but didn't think much of it. --Victor

Wow they sold fast. Anyone want to tell us who bought them?

The price seems very reasonable. He also has some HP extenders listed. I almost bought them just because they are so reasonable but decided to leave them for folks that can use them.

Those are made from my kits! Nicely assembled too. They are good ones, verified by Jerry Massengale, (gone from the world now), to do 100MHz before having any noticeable drop with scope signals

I believe that my scope really has some problem: After performing the Auto DC Balance Routine procedure, a problem occurred: I adjusted the trace to the center of the screen, with the volts / div

Hi to All, We all know the influence of sunlight on the red lettering and knobs of Modules. A spectrum of dark red to orange or even yellowish brown is sometimes the endresult. But I think the other

Hi to All, Some time ago I picked this Demo Board up without any instructions attached. On internet there are no "real" hits. Also Hakan Hintze didn't have any information on it. Maybe someone on

Being cheap I ordered this one which are NiCd. https://www.amazon.com/gp/product/B071VZLKC9/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 Bob

Be careful, those are probably NiMH packs. The simple charger in the 211 will quickly ruin NiMH cells. The Bulbtronics pack is NiCd. Here's an updated

I'll spend some time studying the Parametric Measurement circuit and theory, if for no other reason than to marvel at how the Tek engineers designed such a thing, and, well, "just because." A big part
