    I’m curious about the choice of connector for the RF input on the SM200A. Is it just a normal type-N connector or a precision type-N connector? It appears the typical type-N connector is rated for use up to 11 GHz, and the precision type-N connector is rated up to 18 GHz. I know the laboratory grade connectors used on some of the “big box” analyzers can get quite expensive, but I was wondering how much of a difference in actual RF performance there is and what the reason for using N on the SM200A was (beyond being more economical, although that’s a big reason).

    Thanks again.

    Hi Mike,

    The bulkhead connector is from Centric RF, part number C3614. It is considered a precision type-N connector. Particularly good VSWR. Data sheet link below. It is spec’d to 18GHz and in our tests fine up to 20GHz. The main reason for using the type-N was due to customer feedback, mainly revolving around robustness, rigidity, and prevalence in labs.
