| mean | Find the mean or average value of a waveform. |
| integrate | Find the integral of a waveform, the area under the curve. |
| rms | Find the RMS (root mean square) value of a waveform. |
mean(probe="p(d)" begin=time end=time) integrate(probe="p(d)" begin=time end=time) rms(probe="p(d)" begin=time end=time)
| arg name | default | description |
|---|---|---|
| probe | required | The name of a probe to measure. |
| begin | - infinity | Start averaging at this time or frequency. |
| end | + infinity | Stop averaging at this time or frequency. |
The “mean” measure gives you the true average or mean value. The mean value of a sine over a full cycle is zero.
The “integrate” measure gives you the integral, or area under the curve, signed. The integral of a sine over a full cycle is zero.
The “rms” measure gives you the RMS (root mean square) value.
measure sample = mean(probe="v(out)" begin=4u end=6u)
Find the mean value of v(out) between 4 microseconds and 6 microseconds.
measure sample = mean(probe="v(out)")
Find the mean value of v(out) for an entire run.
measure sample = mean(probe="v(out)" begin=4u)
Find the mean value of v(out) starting at 4 microseconds, to the end.
measure sample = integrate(probe="v(out)" begin=4u end=6u)
Find the area under the curve of v(out) between 4 microseconds and 6 microseconds.
measure sample = integrate(probe="v(out)")
Find the area under of v(out) for an entire run.
measure sample = integrate(probe="v(out)" begin=4u)
Find the area under of v(out) starting at 4 microseconds, to the end.
