I'll let you know if it's real or not. Got a legit Keysight over here to compare.
Little update, it's 100% Fake. More info and pictures once my dispute on Ali conclude.
Ok so the case is finally close and the great Ali ruled on my side and was completely refunded. Initially I wanted to return the product, but on aliexpress, you need to pay returns fee. So I ended up opening a case only for a refund and gave the option to return the item if the seller pay the return fee.
I decided to try and buy one for 2 reasons, #1 The seller was specifically saying that they were not fake on the listing (yeah I guess I should know better) #2 Until now I only seen fake Agilent branded 82357B. Most Keysight 82357B were actually original.
They are definitely working really hard on the packaging and documentations.

Now some comparisons of the adapter itself, I circled in red some differences but you can probably find a lot more:
Texture of the case is not the same. Printing is a bit fussy on the fake one.

They use the wrong crystal, missing a transistor, they are not using Agilent 1822-0639 GPIB chip but an equivalent, TMS9914.

The enclosure is not shielded, Led diffuser doesn't have the same opacity.

They are not using exactly the same Bus transceiver. Should be 75ALS162, they use an older version, SN75162B.
