Portable Spectrum Analyzer

[spongella]

A small handheld battery operated spectrum analyzer went on the market and covers up to 960 mHz. Price is around $50 and has lots of features. It could be used for OTA signal checking. The $50 tinySA spectrum analyzer is here!

I might get one for general tinkering as my main spec analyzer weighs about 40 pounds. Too bad it doesn't scan up to 1500 mHz for use with FTA IF signals.

Why does the picture have two coaxes? In and out?

Why does the picture have two coaxes? In and out?

The inset picture shows the upper input is labeled "HIGH" (240-969MHz) and the lower "LOW" (100KHz-350MHz).

What is difficult to guess is why there's a bidirectional arrow on both ports.

The R&L website has a more comprehensive rundown of what's there.

Not sure why they chose 50 ohm in that frequency range.

One is for "lower band" operation,the other is for the "higher band" operation.

I know I have had an order in for one, but have not got the shipping notice yet.

Price has escalated too.

I believe those on eBay and Amazon are clones.

look at the link in post #1, the vendor *+* will honor the existing price, 49.95, also at the bottom of that web page , there are coax adapters for the unit, where others have almost doubled in price (? clones , )

(? clones , )

Who knows, but all authorized vendors are still showing $49 so. So I would not worry about it. You can pre-order from them.
