Its the 8516A 40GHz testset !?
The manual outlines that FW 11.88 is required and SN 2812A or higher.
Yes there are hardware changes, the CPU and sweep board have different part numbers , the 8516 uses a internal doubler to use a 20GHz source the doubler is controlled over a controll interface on the back of the testset which is connected to the 8410 interface
connector on the 8340 , I assume that HP changed the CPU board to be able to control the 8516 and discard the 8410 controll.
I ordered a CPU board on ebay for $75 and will change it out to see if it works, if not i will also change the sweep board?

?What¡¯s the test set and does it provide any reason why it requires a newer serial number source? I had a compatibility issue with my 8341 and 8510C but it was firmware related and simply fixed by flashing newer firmware (I believe it needed
the April ¡®92 though I can check to be sure if you¡¯d like to know). I have a copy of this firmware but you can also download it from ko4bb (FYI I found the 8340 and 8341 firmware to be identical). If there are actual hardware changes needed I¡¯d be curious
to hear this too.
