I wonder if anyone knows of a project or kit that uses a 'scope timebase
output as the basis of an HF spectrum analyser. My aim is to make something
that would be useful for filter work so I'm not necessarily looking for
very wide frequency sweep.

TIA,


Charlie.

Hi Charlie,
For very little money, you can buy the miniVNA:
http://www.miniradiosolutions.com/

That will far outplay anything you can build. Because it makes use of a PC,
it will have features well beyond a simple SA + tracking generator. In
addition, it's a vector device.

Their scalar network analyzer looks awesome too!
There's an amazing lack of "boatanchor" hardware
in these devices.

Not even any condensers.

Dale,

That is neat but it works out as over £200 here (around $300). I
will bear it in mind as it would be great for antenna work using a
laptop.

Thanks,


Charlie.

Just seen an add for it in this months RadCom, Martin Lynch has it
at £259.95 ($426)!

For what it does- that's a great price.
I have $14K in my HP.

That's a pretty good price, but if you're prepared to import it yourself, you
can save some money. My HP and Avantek SAs cost over £35000 together!

You could build a N2PK VNA which is pretty accurate.
