Q: Dear Sir , I have purchased Your device; it is a very smart product, but,currently, I was not able to start the use properly. In particular, I have installed last and previous versions of NTW SW on XP, W7 and W10 , but when I start the sweep in continous mode the signal level showed, with the spectrum analyser input terminated on 50 ohm, is at the top of reference level. in the dialog box at max signal level is presented somethins as 12500 dB. Could You please give me any suggestion to obtain the correct working. best regards saverio

Uggernaut In this case, the mixer is burned or broken down. If you have used it before, if you add more than 10dbm signal to the test port, the mixer may be burned. If the item is new, it's possible that the transport electrostatic has broken down the mixer. However, this probability is only 1%.

This is a well built unit. A lot of software for it can be found on the internet a preamp would make it even better, excellent ones can be found on BANGOOD too. All in all I'm content with this unit.
