    from order view
    There is no paper manual. We preserve nature and trees. There is no usb cable. why? But the device itself is on 5+. Very high quality. I recommend you to buy!

    A useful gadget!
    A useful gadget! It covers all of the frequency ranges in the description in a tiny and portable package, and interface with the PC smoothly (the software is free btw). Once you figure out how to use it, It gives the high capability to look at the RF environment whether indoor or outdoor and, at such a low price! But I hope the setup could be a bit more organized.

    Nice tool Affordable spectrum analyzer. Enough for mid performances, I use it to coordinate arround 25 microphone and personal in-ear systems and I have good results. Maybe de USB could be in one side instead of down, so you have nowhere to leave it.

    Tip: Shure mics clip such as SM57's fits perfect to handle it.
