Hello,
Does anyone know if a verification data disc that comes with a Verification Kit and is labelled for an HP 8720 can be used in an HP 8510C?
The HP 8510C manual states that this can be a cause of verification failure, but I would like to understand the cause and if conversion could allow the use of such a data disc.
Any info is welcome.
Best regards,

The verification kit disks for 8510 and ALL 87xx are fundamentally different and can't be converted. The 8510 disk has only the factory uncertainties on it and the user measurement uncertainties are calculated during the sysver process. The 87xx disk have files with factory and user uncertainties combined, so there has to be hundreds of files to cover every configuration of cables and cal kit load type, parameter, magnitude and phase. If your verification kit has been calibrated recently, we should be able to recreate a disk for it. If you got it second hand with that old 8752A, then maybe not. We don't keep the data forever. If you send the kit for service and it has floppy disks in it, we can reuse your disks for the new data. We can't get the old double sided floppy disks any more, so we have to reuse them. These old analyzers are long out of support and floppy disks are waaay obsolete, so this is best effort support. If you only have an 8720 disk, but you need an 8510 disk, when you send the kit for service, put a note on the disk stating you need the 8510 disk and we can repurpose that 8720 disk.
Hi, thanks for the detailed reply. Reading the 8720 manual I gathered as much on the data difference. Unfortunately it is only for hobby so the price of a service (I read something like $3300) is too high (actually the same as the whole 8510 system I managed to source from parts). I have not purchased the second hand verification kit yet as I was trying to determine the value to me with only a 8720 disk that it comes with.
"If you got it second hand with that old 8752A, then maybe not." Sorry confused your analyzer with another. The statement still applies to any verification kit data. We don't keep the data forever.
No, you cannot use the 8510 disk on the 8720 series. The file structure and data specifications are different.
When you send in your kit, ask for a 8510 disk also.
