Hi.
How do you measure C/N or NF of Low-IF Reciever which doesn't have much Gain ?
![Kiss Kiss](https://designers-guide.org/forum/Templates/Forum/default/kiss.gif)
Generally Noise Source for NF Meter is valid from 10MHz.
I can't evaluate C/N reliably using Spectrum Analyzer since
Receiver doesn't have much Gain.
Is there any practical or reliable instrument in commercial ?
Noise/Com Inc. has good solution ?
