⭐ Siglent SDG7102A 1GHz Arbitrary Function/Waveform Generator Review part 2 of 3 0019

I demonstrate some of the operation modes and and show issues I found in my evaluation of this Siglent SDG7102A 1Ghz Arbitrary waveform Generator. Parts 1 & 2 will be the unit in operation and part 3 will be a look inside.

In this part of the review I go over the the IQ mode; direct output and RF modulation, the spectra of the pseudo random noise, and pseudo random binary sequence (PRBS) mode and eye diagrams.

This beta unit was sent to me for 3 weeks for evaluation by Siglent Technologies North America. They authorized me to open the unit and show the inside which I do in part three.

The SDG7102A beta unit does many things well, but it has issues. Siglent has seen part 1 and will see parts 2 & 3 and will make improvements based on my findings. That is part of the reason they sent me the unit to evaluate. They have promised to send me an updated unit once they address the issues I show in this set of reviews.
