Looks a lot like the NanoVNA. Interesting.

Like the innovation here. The test equipment you can afford is far more useful than the high end equipment you can’t afford and don’t always need.
Thanks for sharing.

IMSAI Guy has a couple youtube videos on the unit. In one he compares to the SA in an HP8921A.

It apparently has a lot of phase noise and spurs which detract and disturb close in measurements.

I don't think it would be useful at all for measuring modulation.

It may be useful for aiming TV/FM antennas or in a pinch checking a RX multi-coupler ,

For a panadaptor on a RX IF output, an SDR receiver would be better performance.

Seems to work fairly well for casual monitoring considering it has a display. And it does other things like a programmable signal generator and its only $50

Apparently the firmware is being refined. I will be watching this development . Sometimes your worst tool is actually your best tool at the moment.
