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). Expect to pay a fortune though! Kind regards, Ben Mercer *From:* Jonathan Stewart - BV - Principal [mailto: [email protected]] *Sent:* 11 August 2017 19:37 *To:* [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! Regards, Jonathan Stewart EMC Manager Curtis-Straus "This message contains confidential information.
