How to index the bandwidth of the spectrum results.

Pls see the attached vi.
The display is symmetric, so does it mean only half of the data is useful.
If so, how can I index the bandwidth due to the measurement setting.
 
Thanks,

Hello turbot,

All of the data in your display is useful. You could discard half of the data if the spectrum was symmetric around the Y-axis. However, your data appears between 0 and 10 MHz and appears to be symmetric about some point in between. All of this frequency data is useful.

I am not clear what you mean when you say that you want to "index the bandwidth due to the measurement setting". Are you saying that you'd like to change the span of the power spectrum? Could you please clarify what you are trying to accomplish?
