Hi!
I have some problems in measuring some parameters:

1) Why the peak to peak value measured with the cursors different from the one calculated with .meas ? (look the orange line)

2) Why the ripple calculated with .meas is different from that calculated with PARAM ?? (look the light blue line)

Read the help information.
You are using the cursor to select a specific point of the entire waveform.
Since you didn't provide a specific point of measurement in the .meas statement, LTspice found the largest PP value along the entire simulation.
