Hardware versions ...

 

Hi, a very interesting device - and I'm sorely tempted, but on a restricted budget so looking for a used unit.

Is there any documentation on the various hardware revisions and the differences between them ? Just in
case there are any problematic versions.

I have also seen mention of an -H version - what is that ??

I have seen a UTube video describing it used with an external mixer to produce a tracking generator
to look at filter performance.? I already have a small selection of SMA mixers and that would be a very
useful tool.

TIA
Dave
 

There are no HW revisions, all manufactured are the same design.
Do not confuse the tinySA with the various nanoVNA(-H/F/V2)? devices.
For purely filter analysis you are better of with one of the nanoVNA

Dave,
? Erik and hugen targeted the tinySA for those on a restricted budget like students and electronics enthusiasts.? R&L is selling the unit for $49.99 USD including accessories.? Since the tinySA has only been marketed recently it may be hit or miss finding a used unit and you may not find one for less than $50.00 since it is being sold by some venders on eBay for more than that.? I've also got a few mixers, some of which retail for more than the tinySA.

? I agree with Erik that if you already own a NanoVNA device that its S21 through function is better for measuring filter performance.

?Erik has packed a lot of spectrum analyzer features into the tinySA and on top of it has included some pretty nifty signal generator capabilities.? If your interests primarily lie below 350MHz then I highly recommend the tinySA.? The 240-960MHz band has stated limitations, so you have to evaluate those limitations with your own requirements before considering purchasing.
