I was looking into different options for measuring phase noise of some oscillators and standards I have under test and came across the HP 3048A. Now I do not have one set up, but it does look like I technically have half of it (a 3563A). It officially came with the 3561A, but the 3563A and 3562A are incredibly similar to that. Will the software support the 3562A or 3563A, or does it absolutely have to be the 3561A. I did see I will probably have to occur the phase noise test fixture as well as an 8662A or 8663A, but that is a later problem. Should I look into the finding the other half of the 3048A (11848A fixture), or is there a different method/piece of equipment I should look into?
I would love to hear some thoughts from other people who have experience here or have gone down a similar rabbithole
