    Fast delivery It did not exactly fit my needs and expectations. The analyzer needs at least a 30dB amplifier otherwise it is as deaf as a stone. It does not even indicate a a local FM radio station with an VHF antenna attached to it - unless an 30dB amplifier is in series with the antenna. I intended it to use on the IF exiting my FT1000D as a spectrum display but the bandwidth and resolution are not sufficient for such an application. The lowest span is 3Mhz and the lowest RBW is 5Khz /Kc. The display is bright and clear and very good to read. It might be a good idea to buy an additional rechargeable lithium battery for it.

    Improved version with screen that can be used stand alone without needing a computer to see results. Works fine but for lower signals a 30 Db amplifier is recommended. I've ordered one but iy hasn't arrived yet (or maybe is waiting me to pick it up at work when Coronavirus crisis ends). I've also ordered a battery toavoid having to power it via USB for full portable use.

    Apparently it works well although it has little sensitivity, since it has a single control it is somewhat complicated to configure for a specific measurement ,it does not provide manual of use, this version is improved since it has installed the battery, also includes antenna and USB cable. It does not indicate the battery level.

    A good gadget, I use it with a noise source and a return loss bridge. It's a pity that the software is poor: a better way to set center frequency and span would be great!

    practically speaking it is USELESS!!! it is completely uncalibrated and, even following the poor calibration instructions, doesn't help. and I am not talking of 1 or 2 dB but 10 and even more dB according to the frequency and the level of the incoming signal. in the attached picture you can see an FM video signal. the central carrier is the video one while the 2 lateral are the audio carriers, 6.5 MHz apart. at a RBW=100kHz the 3 are so distorted that it's impossible to analyze them! more over the 2 audio carriers seem to be some 28 dB down the video one: and that's not true! they are 15 dB down when measured with my spectrum analyzer!!! so this equipment is really useless and I am completely unsatisfied!
