I have had customers report problems with Chinese ones above 3 GHz, and others say they are okay - I have never measured any myself.? If I had a 6 GHz test set, and intended using at 6 GHz, I would probably be tempted to buy the Keysight ones, despite the much higher price. However, the VNA cal kit should take out the errors introduced by the adapters, but if there's a considerable loss, as some have reported to me, it will degrade your performance.

There's quite a bit of information on the 8753 here
