RE: Anechoic chambers: risks of energy leaking out

Hi again, Covering comments since I last posted - yes chokes may provide sufficient attenuation for the purpose - but to confirm this all the possible issues need to be considered. With a waveguide beyond cut off, filling the hole with a dielectric effectively increases the frequency that it

RE: Anechoic chambers: risks of energy leaking out -ERRATA

Sorry - errata where I said filling the hole with a dielectric effectively increases the frequency that it will pass that should read filling the hole with a dielectric effectively decreases the frequency that it will pass regards Tim Tim Haynes A1N10

RE: First EUP Regulation implementation regarding standby power

I saw written... Considering the fact that if device is used in heated location than reducing its power (active and stand-by) saves no energy I came to: Let's start from reducing outdoor devices stand-by mode ? ;-) Piotr Galka On that basis, we should also consider reducing the power (active

RE: Anechoic Chamber: Pass-through vs. Bulkhead

Hi All, Conventional wisdom is, as stated, to bond the shield of a cable, hydraulic pipe, or any other electrically conductive - non-energised item that penetrates the shield wall. This is usually done with a purpose made bulkhead connector and is, again, usually done at a purpose made access

RE: FCC Part 15.109 and 15.209 Radiated emission limits

Hi Andy, In the UK it is the same. Developers of radio equipment are required to suppress the harmonic and spurious radiated emission levels to a level lower than the general radiate emission limits given for domestic environments [for most of the spectrum, this is true - there are some

RE: Pacemakers

John, Is WG15 also dealing with combined pacemaker/defibrillator units? I have a friend who emigrated to Greece from the UK because the anti-theft devices at UK shop entrances use to trip the defibrillator into action. A couple of joules across the heart is apparently equivalent to a couple of

Ed, I can extend the theory of unexplained attraction to other areas. when the screened room door has a brass surround with finger stock mounted within, then a) people will stand on the door frame even when you tell them not to. b) people need to poke at the finger stock to check how

Hi All, I had some equipment calibrated by a.n.other accredited calibration house - chosen by the management because it was cheaper. Things were fine for a couple of years -then the problems started. The manufacturers would have calibrated each module within the equipment to ensure that it was

Hi, For historic interest. Way back in the early 1970's I was employed by a company that made thermocouples. The smallest was 0.5mm diameter and was sheathed in stainless steel. The actual thermocouple wires were insulated from the sheath and themselves by magnesium oxide. We also designed,
