Why are the NF, Output NSD, Noise Floor, and SNR displayed as infinity in ADIsimRF when opening the ADMFM2000.sgc example file, and how can this be resolved?

This is a known bug in the 2.0.0.29 deployment of ADIsimRF. It will be fixed in the next deployment. A work-around that seems to work is to go to the data fields for Stage 2, 3, 4, and 5 and change some of the values. For example, change the power gain of stage 1 from 11.31 to some other value and then back to 11.31. You may have to do this a few times in different fields. It will eventually trigger a full re-calculation and the fields in the results box will update correctly. Regarding the power gain and voltage gain, it is noted that in a signal chain where the input and output impedance are the same (50 ohms) but there is an impedance difference inside the chain, the power gain and voltage gain can come out the same.
