The RBW is 10kHz, the attenuation is 10dB. The TOI appears to be about 11dBm. The noise floor appears to be about -100dBm in a 10kHz BW as expected. I've used the sample detector. This analyser has 1000 data bins across the span so it's OK to use the sample detector on this span and RBW setting.
You can see that the spreadsheet prediction and the analyser plot agree very well in terms of the IMD levels and the noise floor.

Thanks. Can you show me the step-by-step breakdown how you get the answers in your attachments? I am confused about the calculations...I only have had the spectrum analyzer for 2 months and has not got a degree or PhD in electronics engineering
