Lothar,

On 9th August 2023 you offered for sale a 130 MHz to 20 GHz 8703A? lightwave analyzer.

You stated that had bought 2 and "I removed the optical testsets to use them for parts"

You went on to say

"this is a great unit for someone who wants a compact VNA but can not afford a 8720B or for someone who has a broken 8720B and wants to get it back running"

Clearly from this you considered an 8720B to be more valuable than an 8703A with the optical test set removed.?

Then on 29th March 2024 you offered for sale what you said you believed with an 8720B. Anyone that receives the list via email will have the link, but the link is no longer valid as you deleted the posts - see screenshot of what I can see as an admin.

You wrote it was offered for sale on behalf of a widow of a friend, an

"HP VNA? 130MHz-20GHz , appears to be 8720B no sticker on unit.? , good condition $1650"

As you know, a potential buyer from Iceland backed out of the deal when he became suspicious that the item with no label was actually the 8703A you had advertised 6 months earlier. The differences and similarities between the? photographs are as follows.

1) A label to the right of test port 2, with part of the label scrubbed out is seen in all photographs

2) A label under the test port 2 is seen in all photographs

3) The part number which was clearly visible on the photograph posted last year has been removed.

I have attached 3 photographs - two clearly showing the model number is an 8703A, and another with the model number and function removed, and it just showing "130 MHz - 20 GHz analyzer" rather than the "8703A 130 MHz - 20 GHz Lightwave Component Analyzer" in the photographs posted previously.

F1EKU has since provided his view that the instrument you were selling was indeed an 8703A. I have not checked out F1EKU's comments, but I am even without looking, I am sufficiently concerned about this to ask for your comments.?
