Good Morning to the group,
I have an old VNA, I think it's what is called an H. I'm not sure if it's an original or a clone either. If possible I would like to take advantage of some of the semi newer features that this unit does not have. I have been working to update the firmware but am not able to get the device in DFU mode or maybe it is but it's not showing up in DfuSe Demo software. I know this is a super noob question but feel that maybe another user could give a nudge in the right direction.
I was able to find some of the reference material in the Wiki and did do some searches but so far no hard info on the older unit as to whether or not they are upgradable.
Thanks in advance.
Andy,
