I have purchased a Copper Mountain VNA and I have the ACM2509 automatic calibration kit that was purchased with it. I would like to use the calibration kit with my E8362B PNA. Is this possible?
The original post had a Copper Mountain electronic calibration unit - not one from Keysight, Rohde&Schwarz or Anritsu, but that does not change the basic principle.
It still seems a difficult problem to me.
First one needs to work out how to control the Copper Mountain electronic calibration module. I don't suppose that is too hard to be honest, but you don't really know for sure. Worst case it could use some level of encryption, although I would doubt it.
But if you put the electronic calibration unit into various states, you will not know what the impedance of those are. You could probably measure them with the aid of another cal kit, but that has introduced extra uncertainty. Maybe the data is on the Copper Mountain cal certificate - I don't know.
Then you have to write all your own calibration routines.
I'm not saying it is an impossible task, but hardly a trivial one either. Especially when you consider a Keysight N7552A 2-port 9 GHz type-N ECal is less than $3000. I question the logic of bothering.
ACM2520, not 2509
Using a mechanical cal kit from one manufacturer with that of another's VNA is usually possible - my own company produces mechanical cal kits which will work with virtually any VNA. But unless Copper Mountain have reversed engineered the HP/Agilent/Keysight electronic cal kits, you are not going to be able to use a Copper Mountain electronic cal kit on a Keysight VNA. I would be 99.999% sure that is will not work.
The big 3 manufacturers of VNAs (Keysight, Anritsu and Rohde and Schwarz), all use different methods of specifying the parameters of their mechanical calibration kits. But the parameters can be converted. For example, the C1, C2 and C3 values of a Keysight open, are all 1000x the C1, C2, C3 values of a R&S open - the C0 values are identical between both Keysight and R&S.
Both R&S and Anritsu use offset lengths, whereas Keysight used an offset delay. These can again be converted.
Copper Mountain follows the system used by HP/Agilent/Keysight for mechanical cal kits, rather than those of R&S or Anritsu. But I doubt Copper Mountain would have been able to reverse engineer the Agilent/Keysight ECal protocol, to make their electronic cal kits compatible with Agilent/Keysight VNAs. Ask Copper Mountain if their ECal will work with Keysight VNAs, but I would be pretty sure they would not. I'm sure Keysight would not support the use of Copper Mountain electronic calibration modules.
Well I do not think that you need to reverse engineer Agilent/Keysight ECal protocol.
The key thing is to control electronic calibration unit and pick up particular readings from each state, apply factory cal coefficient from electronic calibration unit, and creat cal set for VNA. In such case you will use some macro or external utility to control VNA and electronic calibration unit.
The thing is that electronic calibrators from Keysing, Rochde&Schwarz or Anritsu are very well made, so the mechanical and electrical properties are very stable over time.
