Since you decided to send this both here and email, I'm only going to bother replying once, here.

> I stumbled across the spectools code, and found it very useful. Thanks a ton for this! I am using a 2.4x wi-spy device. I had a few questions about the same, and I was wondering if you could help me out:

There is code in the 24x specific file for setting it. There is currently no interface in the UI for controlling this.

The 24x has somewhat limited range setting capabilities if I recall.

Depends on the resolution of the scan, etc. Timing data is encoded in the sample records if you want to add instrumentation. There is currently no display for this.
