Something else I see is this: for calculating power dissipation for R2 resistor we use .meas Prg1 avg V( *DRV1* ,G1)*I(R2), but for calculating the power dissipation for R3 resistor we use this .meas Prg2 avg V( *IDRV2* ,G2)*I(R3). So, in one case we use a voltage, and in the other case we use a current. WebAug 30, 2024 · .meas tran Frequency param 1/ (T2-T1) measures the frequency of waveform V (v) by taking the reciprocal of the period between its first and second rising zero crossings of the plot. Replace V (v) with your voltage or current waveform. Change the =0 if your signal has a DC offset.
