8340B or modified 8341B?

[pe2ben]

Hello,
I have a 8340B with a N RF output connector.
On other 8340B pictures i only see SMA RF output connectors.
Could it be that i have a modified 8341B or are some 8340B's are delivered with N RF connector?
Thanks, Ben

Interesting - I'm only ever seen the 8340B's with an APC 3.5mm connector on them (not an SMA) but I think that HP did do a specific version of the N-Type connector that they specified up to 26.5GHz (or maybe it was 20GHz, can't remember I looked it up quite some time ago) so there might have been an option to get the 8340B with that as the RF connector.

That said, I looked for a HP catalog that mentioned the units and saw this:



So maybe what you have is a frankenunit...

Hi Tony,
I read that also.
I hoped that maybe an older version had the N connector because the calibration sheet inside with the correct s/n# show me calibration data range is including 26.5 GHz. Strange...

My 8340A had an a APC-3.5mm connector initially - but it was broken, so i replaced it with an N connector from other HP gear that was specified up to 26.5GHz. At least for the 8563E spectrum analyzer they had to made a 'high-frequency' N connector i guess...
