Re: HP 10811-60085 (10 MHz OCXO) No hits when searching for data...
I spotted my mistake as well. The only 10811- I had in my junk box was a -60111 but I decided to try it in spite of not being specified for PN anyway. I also decided to replace a few capacitors around

Re: VNA Resonance Methodology
And if you want to do a first-order correction for fringing, replace the length with [length + 0.9*radius]. This correction is important if the coil length is not very much greater than the radius.

Re: VNA Resonance Methodology
Hi Jinxie, Back to the fundamentals! L=n2.mu.S/l With mu=1.26.10-6 as your inductor is on air? S in sq meters l in meters This usually works well for me! Hope this helps Jinxie Renaud

Re: VNA Resonance Methodology
How did you connect the LC to the analyzer? Any cable? If yes, did you perform the VNA cal at the DUT end of the cable? Tom -- Prof. Thomas H. Lee Allen Ctr., Rm. 205 420 Via Palou Mall Stanford
