Are you aware that the 8530A also uses different IF and, IIRC, also the sweep trigger board??

Dear Colleagues,?
Does anyone of you own an 85101C display unit with option 011 and would be able to download the contents of the PAL security key 08530-80004 (option for the 8530A microwave receiver). I have an 85101C display unit that I would like to use for antenna measurements, I have the operating system on a LIF floppy disk ready to reload, unfortunately my 85101C unit does not have option 011 (dual identity 8510C/8530A). I would be extremely grateful, I think that the contents of the PAL would be also valuable for other microwave hobbyists.
Best regards,
Wojciech
