4.0 Selection of Output Quantities and Frequency Sweep
==================================================
After a circuit has been input, but before calculation beings, you will need to
select those quantities you wish to observe and the frequencies at which to ob-
serve them. There are two ways that the program can provide output. printed
table of up to 50 quantities per frequency, or a displayed plot.
Only one method can be selected at a time.
Available output quantities are node voltages, branch voltages, branch currents
branch power and ratio of any two quantities. Node voltage zero is not avail-
able for output, but is always 0 volts at 0 degrees. A branch voltage is the
voltage across an element. It is the node voltage at the positive node minus
the node voltage at the negative node. The positive node for a controlled or
independent current source, by convention, is the node where the current leaves
the source (the TO node). The positive node for resistors, inductors and capa-
citors again by convention, is the node where current enters the element ( the
FROM node.
