That’s no doubt true, but British Telecom is pressing for EMC control to higher and higher frequencies, so the UK position may be changing. With best wishes DESIGN IT IN!

From: Ben Mercer [mailto:[email protected]] Sent: 14 August 2017 15:58 To: [email protected] Subject: Re: [PSES] Seeking 17025 calibration vendor for mixers and waveguides Hi Jonathan, You have your work cut out I’m afraid. During my time at a test lab we never managed to obtain accredited calibration for mixers above 50 GHz. The national accreditation body (UKAS in my case) would however accept a manufacturer calibration in lieu of an accredited calibration (we used Keysight <110 GHz and Farran <220 GHz). The most likely candidate, in the UK at least, would be the National Physical Laboratory (www.npl.co.uk <http://www.npl.co.uk> ). Expect to pay a fortune though! Kind regards, Ben Mercer From: Jonathan Stewart - BV - Principal [mailto:[email protected] <mailto:[email protected]> ] Sent: 11 August 2017 19:37 To: [email protected] <mailto:[email protected]> Subject: [PSES] Seeking 17025 calibration vendor for mixers and waveguides Does anyone have a good source for a 17025 verification/calibration of mixers and waveguides? I have a set of OML mixers with diplexers that cover up to 220 GHz. The diplexer seems to be a problem for most labs, let alone the frequency range. I have other two port mixers as well so any leads would be much appreciated!
