The device is the more recent S-A-A-2 which can be used up to 3GHz. It works very well with computer software when connected with the included USB cable. This particular item ships with a 1900mAH battery and a set of test connectors
The S-A-A-2 is a completely new design not based on the original NanoVNA by ttrftech. S-A-A-2 does not use harmonics; it uses 2x ADF4350 to cover up to 3GHz. The linearity and dynamic range are improved. The S-A-A-2 design is open source, which means anyone can manufacture it so be careful when buying cheap imports cheaply.
The S-A-A-2 always powers up in the uncalibrated state, remember to calibrate for accurate readings.

The red LEDs on the side are supposed to be a battery level indicator. The battery last for a good hour or more.
The unit comes with a top and bottom cover, which is plenty for up to 1GHz (and it saves on shipping). Above 1GHz you can fit a thin aluminium cover around the sides – I’ll send you a video to illustrate.
