N male calibration kit
|
Hi All
Some years ago I bought a N male clone calibration kit which is a HP85032E clone kit. It is not that bad(pretty good) and data are very close to what can be found on the Agilent homepage. To day I bumped into the kit again on Aliexpress at the following link fe1303fMMImSf <. 4fe1303fMMImSf&algo_pvid=6d6a9d32-85a8-428f-a09e-b2a6fc1e830e&algo_expid=6d6 a9d32-85a8-428f-a09e-b2a6fc1e830e-1&btsid=afe902d6-210b-40cb-9ac8-21edca20b2 40&ws_ab_test=searchweb0_0,searchweb201602_10,searchweb201603_52> &algo_pvid=6d6a9d32-85a8-428f-a09e-b2a6fc1e830e&algo_expid=6d6a9d32-85a8-428 f-a09e-b2a6fc1e830e-1&btsid=afe902d6-210b-40cb-9ac8-21edca20b240&ws_ab_test= searchweb0_0,searchweb201602_10,searchweb201603_52 So if you purchase a set I can provided the data to enter in the NanoVNA-saver and you will be in good shape calibration male N Kind regards Kurt |

The male short Offset is 18.5ps The male open Offset is 20.5ps or if you want to enter the C coefficient then: The male open Offset is 17.4ps C0=62.14 C1=-143.07 C2=82.92 C3=0.78 For the load you may measure the resistance by mounting it in a female bulkhead adaptor and sending a constant current of 100mA through the load and measure the voltage drop followed by using ohms law ? The might for the load be an inductive or capacitive parasitic component. Try to sweep a short test cable of 0.5m from 50KHz to 9000MHz and observe two traces. Smith chart and a Mag dB trace. The Smith chart shall show a trace running slightly inwards with increasing distance to the circumference and the Mag dB trace flat horizontal up to about 100MHz then sloping downward against a linear running above 300MHZ with linear increasing loss. If not so then tune the load inductance either as a small positive number (inductive load)or negative (capacitive load) until the best possible result. NonoVNAsaver does not yet support shunt C so a negative inductance will do the job adequately. Do not tune the short and open. I attach an image for the s11 return loss. You should see a trace sloping down up to 300MHz like on the picture. The trace have run from 0.1dB to 0.2dB at 900MHz but does not, due to the imperfection of the NanoVNA and lag of error correction. This sweep was for a professional Airline with so to speak no loss, but sweeping a traditional test cable you will see more loss at 300 as well at 900MHz. However the task is never to measure impedances close to the edge of the Smithchart but ensuring above setting helf the accuracy at impedances of interest up to some 5K maybe 10K ohm.
