Output Voltage A voltage output variable of the
form
V(node, [node])
where you
want the total output noise
calculated.
I/V Source The name of an independent current
or voltage source where you want
the equivalent input noise
calculated.
Note
If the source is in a lower level of
a hierarchical schematic, separate the
names of the hierarchical devices with
periods (.).
Interval An integer
n
designating that at
every
n
th
frequency, you want to see
a table printed in the PSpice output
file (
.out
) showing the individual
contributions of all of the circuit’s
noise generators to the total noise.
