Re: BNC Frequency Limit
You'll find type N on an 8566 spectrum analyzer to 22 GHz.? I'd expect the spec an to be more demanding than the frequency counter.? My 5343A counter goes to 26.5 GHz and has a male APC 3.5 mm

Re: BNC Frequency Limit
I suppose lots of things could have happened. It 'might' have had the BNC fitted from new as a factory option, but then again, it could be that the original SMA got damaged and the only bulkhead

Re: BNC Frequency Limit
Systron-Donner 6054B ¨C the 20 MHz -24 GHZ connector on stock models certainly looks like an SMA to me. The 20 Hz -20 MHZ input is a BNC. The S-D catalog calls out (verbatim) ¡°SMA-3MM. Other input

Re: BNC Frequency Limit
The datasheet for that 6054B counter does state that the input is normally an SMA connector. However, it also states that other connector types are available on special order. A standard BNC connector

Re: BNC Frequency Limit
Probably only about 6 gadzillion were used on routers before the inverse SMA became popular... But, no, they didn't catch on in the test equipment world. -Chuck Harris

Re: BNC Frequency Limit
From what I have seen, the 6054B can have either a SMA style, or an N style depending on the top frequency. Never BNC. If yours has a BNC on the microwave input, then someone must have changed it...

Re: BNC Frequency Limit
TNC are several orders of magnitude better than BNC IIRC. Far more phase stable (that's another aspect we haven't mentioned yet). Shame they never really caught on; bit like Betamax and VHS. :(

Re: BNC Frequency Limit
In the past, I have fed 13GHz into one of these Agilent scopes that use BNC inputs and it displayed the 13GHz signal (from an old HP 83752A generator) just fine. There was some loss, but that is to be

Re: BNC Frequency Limit
There was an option to move the high frequency input to the rear panel, leaving only a BNC on the front panel. Might that be what you have? Steve WB0DBS EM17iq09ao

Re: BNC Frequency Limit
I'd expect a 22GHz counter to typically use a 3.5mm connector, but it could also use SMA or N connectors at a push. Note that the highest (frequency) rated BNC connectors I've seen are rated to 18GHz

Re: 3562A Help/advice
It's worth knowing that the variant of the display in the 3562 is different from most other 1345A units. The 3562A service manual includes schematics and these are the best ones to use.? Foolishly I

Re: BNC Frequency Limit
Chuck, it absolutely *cannot* have been an N type at any time in its life or there'd be a ring of some sort around the BNC as they're smaller than the hole an N type needs.

Re: BNC Frequency Limit
6054B and I can't post any pictures right now I'm afraid. It doesn't appear that the BNC has been changed from SMA; looks original and why would anyone do such a thing anyway? Does seem an odd choice!

Re: BNC Frequency Limit
Forgot to say, the 2442 goes to 26.5GHz.

Re: BNC Frequency Limit
First: BNC and N WILL NOT mate properly. while the main dimensions of the center parts are the same (they are 7mm class connectors) the center pin of the N connector is lrger than the BNC center pin.

Re: BNC Frequency Limit
The 6054 has a BNC for its low band (200MHz) input, but uses an N for its microwave input. -Chuck Harris <board@...> wrote:

Re: BNC Frequency Limit
I thought I knew the S-D lineup pretty well, and yet I don't recall an instance where they used a BNC on microwaves. What model do you have? -Chuck Harris <paul666@...> wrote:

Re: BNC Frequency Limit
The word "limit" should not be interpreted as a fixed, discrete boundary that separates "useful" from "useless". The world is analog, so it's best to consider what is really meant in a given

Re: BNC Frequency Limit
Is it the 6054? Are you sure there is no SMA - BNC adapter on it? Perhaps someone modified it...
