I added an N-to-SMA adapter on my KC901V, and followed the following instructions to make SOL calibration components from male Amphenol SMA connectors:
They seem to work well, but I wonder if the values I input under "Calibration kit data" in the FUNC menu are correct.
The physical length of the SMA connectors, from the white disk from which the male pin emerges to the back of the connector where I solder load resistors, etc. is 10 mm. I am guessing that the velocity factor of the connector is around 0.7. Hence the electrical length should be 10 / 0.7 = 14.3 mm.
Should I input 14.3 mm for short, open, and load length under "Calibration kit data"? Or am I misinterpreting the meaning of those fields? Those fields could also mean round-trip delay (requiring a value of 28.6 mm), or expect a negative offset (-14.3 mm).
I would really appreciate it if BG8NPK could comment on this.
