I still have one of those heavy old systems. Really, the only problem I have had with it was the 110/220 AC line selector card needed some help. Yes, you could make an up converter to convert the lower area you are interested in to a range the SA is able to read. Shown below is one I home made.
Also below is a little IF decoder for it.
I never did a whole lot with Labview using this instrument. The program will pull the information out so I could at least save the data for later but that was about it.
If you are interested in making your own converter, the ARRL handbook may be a good place to start.
Inherited a HP 8569B. Range is 10Mhz to 22Ghz (yes thats ghz with a 'G'!). While I was looking to add a SA to my bench, and while I do some RF and VHF/UHF work now and then, most of my SA work would be in the lower range. Much lower - like 100Khz to maybe 10Mhz tops. This SA starts from that point. So my question is - Is there a way to 'extend' its low end range from 10Mhz to 100Khz ? Is so how ? I am open to DIY ideas.
