While on the subject, any one familiar with the Kill A Watt meter? This listing sells for US$26 and free shipping: https://www.amazon.com/P3-International-P4460-Electricity-Monitor/dp/B000RGF29Q I swapped out the 2 mOhm current sensing resistor with a 0.2 ohm resistor (and of course greatly lim

Re: [PSES] God EMC practice

Hi Kim, I've just had a chat with a compliance test lab engineer on this very topic yesterday. He said their measurements have a 3 dB uncertainty between labs. So it world seem when everything is as accurate as possible, 3dB margin would ensure you will always pass, possibly without any margin.

Re: [PSES] Automated vehicles.

Obviously I can't think of all possibilities, but it seems to me that these sort of situations must be corner cases. After all I have never found myself in a situation where my only options are to hit a person or go down a 300 m cliff at 100 km/h. Further more, I won't be driving at 100 km/h whe

And general recommendations also say to reduce common mode current. But obviously this shouldn't have been said too:) On October 14, 2016 9:24:36 AM PDT, John Woodgate wrote: >It seems to me that claiming familiarity with general recommendations >severely restricts what anyone can add. The gene

Hi Rich, > ps:  Three or more axes?  I know x, y, and z.  What are the additional axes? I've heard about six axes robots. I think they are the three translational axes, i.e. left/right, up/down, back/forth, and the three rotational axes which may not be aligned with the translational axes. Thin

Re: [PSES] Handheld or portable voltmeter/ammeter with built-in and adjustable limit function with audible alarm

If none of these meet your needs, you can always find any number of those with a programming API and write a program to do whatever you want. Many support USB interface. You can get a cheap windows tablet as the buzzer and attach to the meter through USB. Best regards, Alfred On May 30, 2016 1

Re: [PSES] Spectrum analyzer and noise floor

I am just now gotten very interest on this subject. I think you mention a key factor: antenna factor. The SA noise floor unit is dBm. After you have added the antenna factor the unit is dBuV/m. Everything else being perfect, zero loss, 0 dBi antenna gain across frequency, etc., the antanna facto

Re: [PSES] SV: Ferrite bead vs. resistor

I don't know your circumstances but I can understand why in some situations adding a resistor help. In many circuits a driver side series termination is part of the circuit design to match the driver impedance to the trace impedance for source termination. The effect of this is that any reflecti
