Dear all,

I would like to obtain the electrical power spectrum density of a signal and the power spectrum analyzer can show the PSD of the signal in (dBm/hz) only but I want the spectrum in (dBm/Mhz) in order to compare it with the indoor spectrum mask of Ultra wide band which is in (dBm/Mhz).

Thanks

      Hi,

      You can use the RF Spectrum Analyzer to perform this function. You can set the resolution bandwidth of the visualizer to view power in wider ranges of frequency. Is that what you want to do?

      Hi Damian,

      actually I used spectrum analyzer and enabled PSD option the result is in (dBm/hz), but I add a (60 dB) scale to the result to convert it to (dBm/MHz).

      Thanks
