I'd like to use the "Load Data" feature under the Input Source (OSC) Noise. Do you have an example file for this and instructions on creating this data?
The Load Data feature expects a csv, tsv, or space-separated value file with column0 = offset frequency (Hz) and column1 = phase noise (dBc/Hz).
As an example, suppose we take the phase noise of the LMK6D oscillator at 156.25MHz:
We can represent this as an input trace like so:
1000 -95 10000 -128 100000 -146 100000 -156 1000000 -156.5
Upon loading into PLLatinum Sim with the Fosc frequency set to 156.25MHz to avoid any frequency-based noise scaling, we see that the oscillator noise impacts the phase noise slightly. In the plot below, the green line is the OSC noise, and the dotted red line is the comparison without the OSC noise loaded.
Also, the top menu includes the option to export traces from within PLLatinum Sim, in a format compatible with the load data options.
