Reply To: Noise figure measurement using an SA44B with Spike software

Hi Richard,

I apologize, I misread your original question. The MRU functions differently in Spike than it does in 2.18. In Spike the Measuring Receiver utility in the file menu is used for measuring generators/attenuators/etc. and as you guessed, requires a CW signal and measures at a very narrow bandwidth. The audio modulation analysis portion of the 2.18 MRU was moved to zero-span in the Spike software. I’m not familiar with the noise figure measurements you are making. Email support at signalhound dot com with your question and Justin will be able to answer your question early next week.

Regards,
A.J.
