Coupling Auto Rules
The Auto Rules for the VBW:3dB RBW function are as follows.
First, if Source Mode is set to “Tracking”: Use 1.0
Otherwise, we go through the following list of detector numbers and find the lowest
numbered detector being used on any active traces (traces for which Update is On):
1.
Peak
2.
Normal
3.
Average
4.
Sample
5.
Negative Peak
6.
EMI Average
7.
Quasi Peak
8.
RMS Average
Use that detector to pick the ratio based on the following criteria:
