For the price , this could be a handy tool , see what you folks think .

Don't look much good for HF or much of the Ham bands. Made for ISM it looks like.

Currently available in five models, based on frequency range:

433M: 430-440Mhz
868M: 860-890Mhz
915M: 910-920Mhz
WSub1G: 240-960MHz
2.4G: 2350-2550MHz


What is the cost, I did not see it.

I don't see any mention of resolution bandwidth, MDS etc. Maybe a fun toy but I don't see anything useful for hams or designers.

A new board is going to cover 15-2,700mHz at total cost of about $260 .

They couldn't get it to go lower in frequency? We have bands that are much lower that 15Mhz. That cuts out 160, 80/75, 60, 40, 30, 20 meters and in the future 600 meters. I'm sure this will be a great unit for those that want to experiment with VHF/UHF and the cost for that is low. The resolution that I saw is limited and I hope they have a range of settings for that.
Thanks for posting. I'm sure there will be folks that find it a useful device.

I think with the cheap availability of DSP related hardware and also the availability of low cost high performance synthesiser chips we will see a mini revolution in the availabilty of low cost tools to allow hams to make spectral measurements that were beyond all but those who could afford test gear that cost as much as a house.


However, I don't think that this analyser is a particularly good example of this trend. The signal hound looks to be an interesting analyser, if a little flawed in places but I think there will be better designs in the coming years.
For example, I think high performance phase noise analysers will become fairly cheaply available soon.
