The E5071C ENA and all associated options will be discontinued, and the last date this product can be ordered is May 31, 2021.
Yes, as far as I can see the product is obsolete, which is a requirement for me to even try to generate keys, I will never touch current products.
Not that it matter much to me either way, but I think the E5071C is classed as discontinued but still supported.
So it probably has one more stage to go before Keysight declare it obsolete and unsupported.
Earlier this year I was still able to request a 30 day trial licence for one of the E5071C VNAs at work.
The older E5071B is definitely obsolete.
