Good morning to the whole group. I am new ?I wanted to be part of this group, as an electronics enthusiast and owner of old HP equipment. Specifically, this is my first post, to ask you what you think of the list that my HP8509A, purchased used about 2 weeks ago, gives me, when in the calibration section, I request the cal data. Following the instructions in the service manual and based on other lists seen online, of other 8590, I have the feeling that something is not entirely ok. I attach a photo of the screen. I am grateful to anyone who can provide me with opinions on the matter. Best regards. Carlo.
