7
Delete the VP marker. (For this example, we are only
interested in the magnitude of the response.)
8
From the Analysis menu, select Simulate to run the analysis
as specified.
This setup specifies that the
parameter Rval is to be stepped
from 100 to 10k lo
g
arithmically
with a resolution of 10 points per
decade.
The analysis is run for each
value of Rval. Because the value
of R1 is defined as {Rval}, the
analysis is run for each value of
R1 as it lo
