Hello-- ...And Mew Metal shielding will keep cats out of transmitters....<g>. 73-- Brad AA1IP

I know they're different Jack, I'm asking how. Cheers [hp_agilent_equipment] <hp_agilent_equipment@...> wrote:

You're comparing apples and oranges. 60hz Magnetic fields are what MU-metal are best at filtering out. Copper screen is best for shielding RF electric fields as radiated from antennae. Jack KG6INX

I understand a changing magnetic field would induce a current in the copper foil, and so the magnetic field would effectively be "used up" by the copper foil, though. Why is copper shielding not

Hi, Mu metal is used because the shielding is from magnetic fields not electric fields. Copper is diamagnetic so not a good shield of magnetic fields that would deflect the electron beam.

The Mu-Metal exhibits ?a shield against 60hz transformer magnetic fields commonly known to induce beam distortion.

Hi guys, Why is Mu Metal used to shield CRTs in scopes, rather than just grounded copper foil? I never understood the precise reason for that. Thanks

Hi everyone, I am posting this here in hopes that someone out there can help me with a MAJOR mistake! I erased the EEPROM to my HP70900B Local Oscillator, this in turns kills using the Spectrum

In the past I've very successfully shipped test equipment. Unfortunately, to pack it right takes strong boxes and good packing materials and these aren't always available for free. The extra size and

Sellers frequently give no choice, they ship how they want to ship and you pay the cost. The pricing formulas are different at USPS, UPS and FedEx which means that for any particular package,

So out of a country of 310 million people, you managed to find a few people who have no clue how to pack stuff. Big surprise. That's what you get for buying from people who aren't professional packers

You can get 100 resistors for cheaper than that from Digi-Key; why would you buy junky no-name Chinese resistors and wait a month for that price? That's what you get for shipping heavy items via USPS.

I think you are being a bit unfair on a lot of Chinese sellers who are pretty honest and safe to deal with. I have bought hundreds of items from China and I would say well over 90 percent of them were

The default stepsize of the 83623A 20 GHz sweeper is 1 kHz. HP in their attempt to extract as much money as possible, made the 1 Hz steps a software option (008). Does anyone know to add option 008 to

He did not inflate the shipping. In fact, they were shipped free along with a bit of test equipment I bought, as the weight of the feet was negligible in comparison to the test equipment. But even if

Not a problem. Ebay only counts one of those feedbacks towards their "star" score. The "star" score is composed of positive feedbacks from unique buyers (or sellers). So the seller isn't inflating his

I suppose this is true, sadly. All the more reason to never use your real identity for online transactions, I fear the day when this will not be possible. For now it only require easily-attainable

Hello Roumen, Could you please send me your schematic for the 8593A power supply? I am working on an 8590B and I think it has the same supply. Thank you Tom Bryan N3AJA

Peter, Contact me off list when you get a minute. Thanks, Steve

Steve Exactly so ...the display modules were a little more transparent in being able to identify the 3rd party manufacturer and model number from the tags on the module. By searching against those you
