11.7.3 Stability margin calculation
To get quicker stability margin results, Bode Analyzer Suite can automatically determine Phase
Margin, Gain Margin & Vector Stability Margin using the Stability margin cursor calculation.
To activate stability margin calculation, go to the cursor ribbon and select the stability margin
calculation method as shown below:
As a next step, select the trace you want to use to derive the stability margin information from. If you
want to calculate stability margin from a memory trace, please link the cursor to the memory using the
link cursor icon in the memory trace. In the following example we want to calculate the stability
margin of the measurement curve in Trace 1:
To start the calculation, click either on the button or activate the checkbox
. Track margin will automatically search the stability margins after each completed
sweep.
As a result you can see the three cursor positioned at the frequencies of Phase margin, Gain margin
and Stability margin. The results are shown in the cursor table and in the cursor ribbon:
