Frequency Down Converter

[catshot]

I will eventually be using the SA-44B pending the collection of ‘information’. My title sort of says it all. The question is: If I’m using an injected LO frequency of 4GHz into a converter and feed the detected output into the SA, is there a function in the software I can set to make the PC output appear as receiving what I want the start frequency to say? I.e. If the signal of interest is 5.8GHz can I tell the SA the start frequency is 4GHz? Thank you for any info provided. Mike C.

You can export the plot to csv and than in excel do the recalculation of the frequency values.

Hi Catshot,

Currently setting a frequency offset in the software is not available. This is something we have wanted to add in for awhile. Thanks for the suggestion.

Thanks guys for all your inputs. I got confused when hendorg said the SA would treat the fixed sig gen as a spike and remove it. Then Andy mentioned max hold and that cinched it. Bottom line for me is I want to start off simple and then get the TG at a later date, should I be doing a lot of ‘sweeping’.

cheers,
Mike (aka. catshot)

Sorry for confusing you catshot. All that info was actually in my post, but you wouldn’t be the first person who didn’t understand what the hell I was on about 🙂

Cheers,
Roger

Well the SA & TG came in yesterday and I’m in the process of ‘getting-acquainted’ with all the bells and whistles. I printed the manuals and now will do some studying and be back later when I get stuck. Great community here, I’m looking forward to learning more. Mike.
