Hi,
I want to measure the ENR of a noise source and which method below provide a accurate results?
1) Using N8975 noise figure measurement , measure the pHOT of the external unknown noise source
2) Using SA eg E4440A
Use marker function, marker noise, marker will show the normalised dbm/hz (No)
Then the ENR= (No) + 174dBm/Hz, Since PSD(dBm/hz) = -174dBm/Hz+ENR
Can anyone tell me the accurate way in measuring ENR of a noise source?
Thanks
