Re: Offtopic: nanoSA

 

To the potential developers:? I would like to point out that spectrum analyzers that go up to 1 GHz are quite affordable - used obsolete HP etc.? And there are new $170 ones already available, such as the RF Explorer.? This is a very nice and powerful handheld unit in a nice enclosure that goes up to 960 MHz.? RF Explorer has other models that go up to 2 GHz.? There are no inexpensive commercially available Spectrum Analyzers that cover 10 GHz, despite the fact that all that is needed to turn one of these other units into a 10 GHz SA is a mixer.? Even obsolete used HP SA units that cover 10 GHz still cost $5000+ and new ones are $40000+.
Is there a need for a $50 1 GHz SA?? Yes.
Is there a tremendous need for an inexpensive SA that goes up to 10 or 22 GHz? ABSOLUTELY!??
An affordable microwave SA, combined with NanoVNA V2 (up to 3.5 GHz), will open up microwave work to legions of people who have always avoided it because they didn't have the necessary instruments.? That would be a very good thing!

To the extent that this encourages present or future developers out there:

A spectrum analyzer, with a tracking generator, that covers "below HF"
through "above UHF", with user-selectable RBW and VBW, for around 50 USD
would be ... awesome!

[FWIW, I'm "blown away" by the nanoVNA ... so my thanks to those
developers.]

If I can say a little something about this Idea.

A tracking generator would not cost a lot more in ressources and would
be a nice addon in a NanoSa.
And the possibility to add an amplifier to the TG to bring the level
to 30 DBm (1watt) would also be cool.

And lastly with the Generator in the TG, if you can modulate the
signal with a tone at a deviation level you can set, we could do some
really nice stuff.

With that said, I have a nice pelican box that could house all of
those nice device with a large rechargeable bank of Lithium/ion
battery lots of cable and adaptors. A Raspberry Pi4, 2 hdmi touche
screen And we have a portable RF labs..

Would it be wonderful if there would be, next to the nanoVNA, a nanoSA
or nano
Spectrum Analyzer?

Well I decided to test what the most simple SA could look like, just
good
enough to test the harmonics level of your signals till 400MHz and
some other,
not too complex, measurements.
Thanks for playing with this idea, Erik.
There was a comment from a Japanese NanoVNA user on Twitter comparing
the use of the Nano to an oscilloscope that is in the same price range but
has poor specs.
They gave an example of JYE Tech's 200KHz bandwidth scope kit for $30 vs
the Nano's capabilities - image attached.
At this time, there is not near enough memory to implement a scope
function - maybe in the version 2 device?
