Help needed identifying an RF connector to an old ADVANTEST

[gissiken]

I have an old ADVANTEST R3272 Spectrum Analyzer 9KHZ to 26.5GHZ that I am attempting to rescue.

The connector in the front is something I cannot recognize. 
Can anyone tell me what this is?

are you sure thats a real connector not a slot machined out for some reason (in house test)?

normally APC-7 right? i am not sure but I think the side cuts look kinda shitty for 27.5 GHz.

Doesn't look like any connector I recognize. https://www.advantest.com/documents/11348/146687/pdf_mn_ER3272_OPERATING_MANUAL.pdf specifies a N-type, so this is likely a custom mod.

Looking around that type of connector appears several time. So that's not a custom mod. But no clue here either.

Thanks for Reply! I don't know anything about this connector. Have order an APC-7 but I don’t know. Waiting also on a Planar Crown connector. Started to look into changing the whole connector to N-Type. Recognize the back end of the connector?

PS! found later on that it was 3,5 mm air dialectic, for those who are wondering. good for 33 GHz.

I think I found it:

That's probably a starting point for you to look for adapters that matches your requirements.

That does look like it, added to the fact that R&S and Advantest collaborated on a couple of products including SAs in the past.

Glad you found your connector. Just as an FYI the APC7 connector is limited to 18 GHz.
