DAQ Settings for Lowered Noise Floor

#1

I’m using the direction-finding application and my noise floor is a sad -69 dbm while looking at a 2.4 MHz bandwidth. I want to zoom in to about 50 or 100 KHz and lower the noise floor as much as possible, the signals I’m looking for are about -105 dBm.

What would the DAQ settings look like to do this?

Thanks!

You can use the DSP side decimation setting to improve the noise floor and zoom in to a more narrow bandwidth. A decimation value of 24 would take you down from 2.4 MHz to 100 kHz.
