Hi, I have 3 reference coax cables, and I'm trying to find an accurate way of measuring their electrical length. I understand a VNA is the best way to do this.
VP is 0.66 and the 3 lengths are 40m, 85m, 350m. I only have access to one end of the cable (other end is open)
The reason for wanting to know the exact electrical length of these cables is so that I can use them to verify the accuracy of a TDR under test.
I have an Agilent 8510C available to use for this test.
Would somebody be able to advise me on how to do this.
