ADS MeasEqn, how to clip to a time window?

[rob70]

I am trying to use MeasEqn to measure peak-to-peak voltage of a waveform, but it has to be at a specific time in the simulation. Other EDA tools allow me to clip a waveform around a specific time window, but I do not see a way to do this in the ADS, with MeasEqn functions.
I don't think doing it in post-simulation is a good way, because I need the measurement to be in a schematic which can be arrayed many times. I can do it by hand post-simulation, but doing it manually for a large array is not practical. Is there a better way to do this?

Thanks, Rob

A specific point could be marked by a certain number of frequency cycles, Build a section of your simulated circuit that keeps count of cycles. Then take a sample-n-hold when it gets to your target amount. Or take two sample-n-holds: a positive crest and a negative (trough).
