Jim N6OTQ: Instead of cutting the power cord why not use these clamp on devices instead: https://www.aliexpress.com/item/1005003686552253.html?gatewayAdapt=Msite2Pc I have used the clamp on ferrite

Very cool. Does this script use an internal PC Slot Card or a USB (like a National Instruments USB), Host device? Ross From: [email protected]

"Because I could": my home grown EMI probe in (isolated..) contact with the lead of a Metcal close to the handpiece For the curious: the Python script used is here

I own two Metcal 13.5MHz ISM bans soldering stations. Both are housed in extruded aluminium cases, and (IIRC) they have a netfilter integrated inside the IEC mains entry. The silicone cable to the

If your power cord is round and has a diameter of 1/4" or less, these guys will work: <https://mgs4u.com/product/double-ferrite-beads/> You'll need to cut the cord to get these ferrite beads on, and

The wired chokes Ross describes are available in a package that includes an IEC inlet connector. If your controller has an unfiltered connector and the extra depth required, you can substitute a

Hi, The Common Mode Choke that I was referring to is one that is “wired into” the EMI Filter. It has two counter-wound coils on a Ferrite Core (donut), and is wired into the AC Power path

I still have one of those. Sent: Wednesday, August 02, 2023 7:45 PM To: [email protected] Subject: Re: [Test Equipment Design & Construction] EMI filtering on power cord

Hi, Ferrite Cores come in different materials for different frequency ranges of suppression. Some are specifically made for Low Frequency and some are made specifically for High Frequency. The best

OK, the interference seems odd, but I can't really explain it. What about Metcal, in your experience?? I know they are about 13 Mhz, but I do have to wonder how well shielded they are. What this

Harvey, I've had the WTCPs almost forever. They don't make a lot of CW, but they are amazingly noisy when the thermostat cycles (off especially, dumping the transformer's stored energy). I've had lots

Ross, Ed, Harvey, Thank you very much for your very thoughtful and elaborate responses. This is very helpful. In my initial approach to this, I was thinking more of electrical, not magnetic field

Have a look at the WTCP series by weller.? Don't get the ones with a temperature control. You change the tip to change the temperature. The tip is magnetic and attracts the heating element.? A

The only soldering irons that are relatively emission-free are the old fashioned heaters that just go when plugged in, or flame heated types. Ever since temperature controlled ones emerged, they have

Hi Radu, There are two kinds of emissions that can be emitted from a product. Those are Conducted and Radiated Emissions and Conducted Emissions. The Conducted Emissions are those (as you said),

Hi all, Not sure this is the right home for this topic, but here it goes. I've been very happy using one of these clone soldering stations and handpieces that accept Hakko cartridge tips. And the tips

LTspice may be helpful for all this ... I'm not volunteering to do it :) but I'm doing my first serious low-noise design in it now. Like any simulator, the garbage in-garbage out phenomenon is always

The originator was mystified by the fact that the measured noise was much higher than expected. The mistake in his noise estimate was assuming that the gain of the first stage is 1. While that’s

Interleaved, please: Oh, I have a copy of Kicad, and just opened the file in that. Since I really haven't used it for anything yet (EAGLE in my configuration works for me), running it on a laptop has

Sorry about this - I realised this afternoon that KiCanvas is still in alpha and doesn't work everywhere yet (eg, mobile!). I added an old-fashioned PDF schematic to
