Hi Sam,
The process is similar for the SA44B except there are a few things you need to be aware of.
You will need to disable the software spur rejection to be able to make accurate channel power measurements. This can be disabled in the “Settings” menu. The SA44B enables this setting by default.
Average detector and Power video units should still be set.
If the traces are stored in dBm units, then steps 3,4,5 will apply.
Since I have posted the steps above, I have a simplified approach to approximating the window bandwidth. This will be possible as well with the BBR files as well.
The window bandwidth can be approximated as
WB = rbw / bin_size(freq between each spectrum bin)
Both RBW and bin size are stored in the BBR file.
I will attach two files that we use as examples for customers.
One is for calculating channel power, the other is for parsing BBR files.
Let me know if you have additional questions or need clarifications.
Regards,
A.J.
