what's the TrueArb technology?

[xzswq21]

Hello
what's the difference between the DDS and TrueArb?
I couldn't find anything about it!
would you please refer me to some papers or references?
i want to work it in details.

Best Regards

Keysight have several papers on it. (I presume that you mean TruForm - or perhaps TruArb is a rival technology).

Basically they interpolate/resample in real time to give very low jitter compared to standard DDS which has a fixed sample rate.

This is a good (if old) paper on the general subject:

TruArb is Siglent's architecture and it delivers better signal fidelity than DDS.
