Hi Ransom It's all a matter of opinion. The 2235A has an aluminised backing on the phosphor to eliminate most phosphor burn risks. However, any type op phosphor will degrade over time (even those

In DC it's called "word smithing", elsewhere it's not referred to so kindly. Some of these guys are good, others have minimal comprehension of the "Kings English". Caveat Emptor Dick, W1KSZ

I usually turn down the intensity on the scope right down if I'm doing something else for a while. But then again, I usually run at a fairly low brightness anyway - there simply doesn't seem to be

I did this with a defunct S3a 1GHz sampling probe. The brige was toast (well, some of the diodes were leaky in reverse bias). Stan helped out by looking up the spec of the original bridge diodes for

Miroslav, Those types of abbreviations or acronyms came into use back in the early days of personal computer communications, when modems were 300 Baud (and then 1200 and even 2400 baud), mainly

I have an 067-0587-02 7000 Series Calibration Fixture. I have no manual for it, so I have no idea how to check its performance/calibrate it before I use it to calibrate my scopes. SN is B031613 and

While writing code for a PIC microcontroller, I have the PIC circuit connected to the scope to see the waveform (sine wave, not changing position for example). I will leave the circuit connected to

I came across this 7904 earlier today on the 'bay: http://cgi.ebay.com/ws/eBayISAPI.dll? ViewItem&item=3801633404&category=45005 Hmm, looks like an OK deal if it worked, as implied. But then as I

It is apparent to me now that a 7S14 would not meet Dan's (Dan Tulloss, Senior Metrologist, National Test Equipment, Inc.) needs. I have one of each of the Tek sampling plugins:

I've been a "ham" for 51 years and "IIRC" is a new one one me! My guess: "IIRC" = "In the Instance that you Really Care . . ." Stan w7ni@...

Can Someone Send Me A .PDF File Of The Operator/Service Manual? Have One That Has Been Hacked Up, And Want To Restore. TIA Greyhawk

After reading Dennis's message, it occured to to me to look up the 7S14 in a Tek catalog. This is just a 1 GHz, two channel, 50 ohm sampler. Tek made a lot of earlier versions of this technology

Got a nice working 475A, would like to replace the original blue/green CRT filter with a nice sharp new one. Ar they commonly available? Also needs the protective cap that fits over the face of the

Good evening, * REPLY SEPARATOR * The 11401 is a 500MHz bandwidth digitizing mainframe, and the 11A32 is good to at least 350MHz if I recall correctly. The combination makes

I once was given a Tek 212 portable oscilloscope that was dropped from a power pole and was in many pieces. The amazing thing was that the CRT was un-damaged. I managed to get it all back together,

The article, by Mark Kahrs, on sampling systems that was just mentioned yesterday on the TekScopes site covers the entire history of sampling systems and sampling test equipment. It discusses in some
