Continuing from Sophia's SURF Project this summer: Plotting the Power-Spectral Densities (PSDs) and Cross-Spectral Densities of two signals.
A continued issue that has been observed in the plots is the random "jump" of one PSD curves. Below, a 1.4 kHz signal is driven with a magnitude of 0.7 Vpp, and connected to the two output ports of the Red Pitaya via an SMC T-Adapter. At the moment, I anticipate that this bug might have something to do with the Real-Time GUI code being used, since this hasn't been observed when running the calculations without it (see below). |
