Yes, it's called an isolation monitor. Bender makes most of them: <http://www.bender.org/> They are mostly used in hospitals and such where the isolation is used to provide redundancy against faults,

Ah, okay, I see what you are talking about now. I doubt you are going to find a generic cheap replacement for your scope the way those are designed. Mark

There is a type of GF detector which works on an isolated system and will trip on the first fault. The way it works is to inject a tiny current wave onto the circuit and observe the voltage change and

The Tek 214 probes are built into the scope and can't be removed without opening the unit. Take a look at this auction:

What model number probes do you have? Mark

I have a nice isolation-variac unit I built, but hardly ever use. With differential inputs and diff probes there really isn't much need for it. I suppose if you work on those old hot chassis TVs

That must be why they are used to power electric shaver outlets in bathrooms ;-) Just joking, we are in agreement, only that you went a bit over the top maybe. Isolation transformers can be used

I'm not sure the typical Tek probe tip will fit the 214 probes.

Well said, Steve! While power by isolation transformer itself is a very safe thing, people usually defeat the safety mechanism instantly by producing the first fault with the scope probe ground.

Steve, Thank you so much. AC connectors with a grounding pins are there for a very good reason. Any isolation should be an absolute last resort. Using an isolation transformer is dangerous and usually

Variac should have been spelled with a "c", not Varik. My mistake Steve

I don't quite agree with the phrase "An isolation transformer allows you to make measurements safely." While using an isolation transformer can let you make a floating measurement not referenced to

Hi all No matter what some of us may think, Canada still isn't our 51st state. Recently, Walter at Sphere made me an extremely generous deal on a manual, and asked for either a USPS international

Far better analysis than I could have ever done Vernonia Northern Has U2145 (156-0096-00 - LM311H) for $1.20 & U2110 (156-0223-00 - LM308) for $1.10 & U2010 (156-0292-00 -- 74L04) @ $0.35 each Chris

Bob, I have a 7B53A with bad switches that I am scraping. I can send you the working 155-0049-02 for $5 plus shipping[$2.06?]. send me your address and it will go out this morning. paypal

Scott, Do a search on Ebay for "tektronix probe tip" - there's tons of them out there, and most are fairly inexpensive. Mark

Hi Walter A long shot - you don't happen to have a 7854 keyboard lurking in a dusty corner? Kind regards Craig

sphere, vernonia northern, qservice, tucker... google the part number.

I have that manual, I cannot find half of A02 board. The full symptoms are these:- 20ns clock?disappeared;- there are 4 selectable groups in the setup screen;- each group has 16 bits available for

Dave, ? This new link does work.??I had already found your file by browsing the group files and was quite impressed.? Very nice professional work.? It looks to me that you have complemented the
