Reply To: Exploring a recording in zero span mode

I was a little unclear above – I understand that you can you can zoom in on the graphs like AM vs time, but I really meant controlling the window position/dimensions in the playback IQ preview graph above the play/stop/pause button.

My workflow is to play the file from the beginning, then pause and move the rectangle slowly in an interesting part (sometimes backing up), then switch and zoom in the AM vs time graph. I loose track of specific event times in the file as I only have a offset in percentage to 2dp and cannot say move the window precisely to a time that I have previously noted.

I forgot to add that I have a repeatable issue when clicking on the graph to move the window when I have very large files (e.g. >> 8 GB) in that the little window rectangle on the preview trace only moves temporarily if too far into the file (> 8 GB it appears) and will go to back to the beginning of the stream after clicking. Finally I note that in the AM vs time graph, when you zoom in the window start/stop time is updated, but the average doesn’t appear to change.
