Hi, I have a HP8568B reporting the battery is low. I have some 8568B manuals from Artek but I can't find anything in them that looks like battery replacement instructions. I know I have to take a

Hi Radu, You don't say what your scare was, but if your doctor deduced that the lead levels in your body are high, it likely didn't come soldering circuit boards. If you have lead in your blood,

John, I think I'd pay you that, add money for gas, house (+ dinner and breakfast) you for a couple of nights just for the company and conversation. Radu. [email protected]> wrote:

Hey, for $2k, I might drive over from ABQ and make that hole in the wall...with all new ducting and fans... I lived in Santa Barbara for 6 yrs and miss the mild climate, foggy nights, and luxurious

I appreciate that - and was just kind of determining it's an option, though pretty pricey new - but not used, please. The seller may have used it to make Cesium Christmas tree ornaments for all I

Metcal made (makes?) a HEPA solution that can be placed on/near/under the bench. I got a used one off the auction site for a fairly reasonable price by waiting for the right deal to come

Ok, there's enough information on the problem now. Apparently, soldering 20 feet away from a cooking area, on the same level of a dwelling, even with doors in the way, with a common airspace, single

Thank you all. Plenty of paranoia here, but backed with some reality - I have young kids and the kitchen is a literal 20 feet from the bench. Being in CA, I have zero alternative options to

Yes. This is quite obscure. I don't know what kind of bench soldering he's? doing, or how often, but there's a range of options out there. I have a very cheap fan and filter, it went on sale for $5,

I think you need to be a little more specific. Do you want a full hood and exhaust outside, or trap the fumes in filter/chemical media? Or, do you just want to get it out of the work zone and

See if you can reach the facilities department at a local university.? They should be able to point you in the direction of a supplier who can meet your needs. Peter

What happens if you take a series of measurements, then disconnect the probes, flip the T 180 degrees, examine the result and evaluate both of them? Harvey

I have a few solutions, and it depends on how you balance paranoia, health, and work to do it. The classic chem lab solution is a fume hood. For a soldering station, you need a vent near the

Hi all, I've had a recent scare with potentially evil metals that can vaporize - you know who you are.... - and absolutely need a good, and hopefully affordable, solution for my bench soldering needs.

I'm not sure what you mean. One can't simply look at the BNC Tee and declare that the ~120ps length of each arm is so short at 500MHz that it is irrelevant. You have to analyse how the system will

Yeahbut but the phase difference shouldn't matter for a comparison of the two waveforms at a high enough sweep rate, surely, as you can visually eyeball individual cycles...?

Has anyone had occasion to remove option 006 and restore the pulse modulation feature on an 8340B? The one I’m looking at seems to have all the hardware in place (A21 pulse modulator board, A9 low

If the 3.5GHz 'known good probe' probe is a passive Zo probe, it might look like 500R in parallel with 1pF up at UHF. By contrast, a 10073C will typically look like about 60R in parallel with about

One take-away from all this discussion is that it's very tricky to make good measurements at higher frequencies, especially with scope probes. It's hard enough even comparing probes attached to fairly
