Clabraion kir data for both the male and female kit
|
Hi All
As promised hereby follows the data for entering into the NanoVNA-Saver non ideal calibration settings for accurate measurements. As discussed the female female adaptor is very poor, but I have created data so it is quire useable when used for constituting a female calibration kit. As Hugen just informed, there are outgoing shipments where the poor female female adaptor is substituted with a better type. When I one way or the other get hold of a new kit with this improved adaptor, I will repeat the measurements to get it optimized including L and C coefficient, and hopefully the NanoVNA-saver then also will include shunt C for the Load. The data I here published is "manipulated" to avoid use of C shunt for the load. Kind regards Kurt |

Hi Carlos
Great, very assuring. Agree photos is a good idea and I did that some time ago when I started to comment this topic. One of these days I will issue a document when to use male and female kit for insertable and non-insertable DUT's. It is quite easy to make mistakes regarding calibration and ensuring calibration is at the calibration plane and not out in the blue air or somewhere inside the test cables.

Got 22e-15 too for C0. See /g/nanovna-users/message/4526 However i know different kits are being supplied. A friend got a low quality short made in a single piece that leaves a small air gap. So we must attach kit photos with the obtained coefs. I need to get a good macro camera... Carlos |
