FS [EU]: ADF5355 Frequency Generator/Sweeper up to 6.8GHz / 13.6GHz

[hp3310a]

I bought this ADF5355 based generator/sweeper thinking that it would be able to produce 13.6GHz fundamentals - maybe because the vendor said it would ("Wide Output Range:Generates 54 MHz~13,600 MHz RF output", product description here https://www.aliexpress.com/item/4000576505278.html).

However it only really goes to 6.8GHz plus a strong 2nd harmonic at the claimed high frequency. Not what I wanted. It also sweeps from 250MHz to 6.8GHz.

The vendor is really uncooperative. Before I invest additional money into sending the item back to later hear that it never arrived, I'd rather make a loss and give it to someone else at a discount. It is brand new.

Price €100 + shipping from Austria.

The spectrum analyzer shows the generator set to 6GHz at +5dBm output with a 20dBm attenuator at the input of the spectrum analyzer + 10dBm internal attenuation from the spectrum analyzer (the cable is a short RG316, so some attenuation from that).
