Hi @Stefan Schippers, I'm trying to sample instantaneous power(Pinst) within a set time interval from a transient analysis plot. My goal is to do something like obtaining Pinst at every 1ns at each cycle (80ns) and that is repeated for 50 cycles. I've tried ".meas tran samp_interval find Pinst at=samplingtime" but that doesn't produce the intended idea. Another thing I tried is to update the start and end time of the transient analysis but .trans doesn't take in vectors. Is there a work around for this? The following images show the Pisnt graph I'm trying to sample and the plot of the attempted measurement (excel).
