Foo – How analyzer data point settings affects the measurement results

Obviously measuring things wrong and then making decisions and corrections based on bad measurement information is a waste of time at best.

I was curious how the different data point (the size of the sample window) affects a measurement.

In SpectraFoo Complete there are the following options to choose from.

In order to keep track of the difference (if any), I took a snapshot via the “TAKE SNAPSHOT” button at the bottom left side of the TF window.

In that same area is a button to display the snapshot overlay list.

This is what the overlay list looks like for this measurement process.

When you’re saving snapshots and then comparing them, it’s sometimes helpful to discontinue the measurement process and clear away any remaining data on the screen so you’re only looking at snapshots. These are the places to stop the measurement and clear the window.

All of the functions mentioned above can be achieved with key commands:

This is what it looks like when you turn off the measurement tool & clear the realtime data while showing all the snapshots.
