Re: Sine modulated PWM voltage source (PWL file=xxx)

Andy,

could it be that I'm assuming a different file format as I posted in the other email:


Timepoint ??????????????????????????V0 Trise. ??Von Ton ?????????????????????????????????????V? ?Tfall ??????Toff
0.000000000000000000us 0 ?0.010us 5 ???32.552083333333335702us 5 ??0.010us 0


Some (undocumented) data formatting? My idea was, that the first parameter is the proceeding point on the time axis, followed by
the start voltage, the rise time, the on voltage, the on-time, followed by another voltage (at the end of the pulse), then the fall time and the off voltage.

I built that python program about a year or two ago and I think that file format could be sprung of a discussion here and someone pointed me to "undocumented"
PWL file formats.?

I may be totally wrong and that example may have only worked before (with other data) by accidence :)

Just to be clear, those two lines of data look like this:
8398.438us 0
+0.010us 5
+-1.598us 5
+0.010us 0?
8463.542us 0
+0.010us 5
+-3.195us 5
+0.010us 0?
which then expands into this:
8398.438us 0
8398.448us 5
8396.850us 5? ?; This one is earlier than the one above it
8396.860us 0?
