Review

We tested the device with Agilent instruments, and we were pleasantly surprised by its truly excellent performance.
Obviously it is much slower in measurements compared to instruments with a much higher cost.
The only problem we found is in using it as a generator in FM Modulation. Ingatti the modulation has a huge distortion (45%) at 1 KHz (25%) at 300Hz and is reduced to 3% at 100Hz.
Probably the DDS is not fast enough to follow the sinusoid at a frequency of 1KHz.
For the rest the quality/price ratio is surprising!
