Hello! :D I’m currently trying the sample codes included in the RF Synchronization Suite which I downloaded from National Instruments website. However, I’m having a hard time understanding the effect of the “phase offset” on the IQ data which I generate (or acquire).
For the generation part, I’m testing the sample code named “PXIe-5673 Phase Coherent Arb Waveform Generation with NI-TClk Example”. If for example, I entered 0° as my phase offset for channel 1 and then entered 10° as my phase offset for channel 2, does that mean that my data for channel 1 is AMPLITUDE1∠0° and my data for channel 2 is AMPLITUDE2∠10° in polar form? If so, do I enter these values before running the code, or while running the code (and after which I click the “Update Phase Offsets” button)?
Thank you very much for your time! God Bless! :D
