How to appoint the time in ADS Envelope simulation?

I made a envelope simulation and get the following results for Meas1[9].
It's a list of Meas1[9] vs. time.
How to describe the Meas1[9] at time=30ps? I just need the value on this time point.
Thanks.

Show me the result of "what(Meas1)".

Try like following.

time_idx=finde_index(time, 30psec)
List Meas1[time_idx, 9]

Hi, pancho, Thank you very much.

Here is the what(Meas1).
