Hello, folks,
I have another problem here to calibrate a 3-port waveguide coupler. Remember I posted a question regarding return loss measurement several days ago. I appreciate UKAS has agreed with our setup since we provided scientific error model of the setup and "initial" derivation of the measurement uncertainty is within scope of ETR 028. Why I am saying "initial" is that we used manufacturers specifications of the 3-port waveguide coupler, i.e. mismatch, insertion loss (coupler port & thr' port), and directivity, etc...). Now, UKAS asked us to provide calibration data of those parameters instead of manufacturers specifications. The problem here is we are requested to calibrate it in NAMAS traceble calibration lab. I have called NIST, the reply was they can't do it. I called HP, they need one week to evaluate ($140 evaluation fee, no matter whether they can do it). I appreciate any recommendations - It's urgent! Thanks, Leslie __________________________________________________ Do You Yahoo!?
