We now need to add our generator and probes on to the graph. Each generator has a probe
associated with it, so there is no need to place probes directly on generators to see the input
wave forms. There are three ways of adding probes and generators to graphs:
The first method is to tag a probe/generator and drag it over the graph and release it - exactly
as if we were repositioning the object, repeat for each probe/generator. Proteus detects that you
are trying to place the probe/generator over the graph, restores the probe/generator to its
original position, and adds a trace to the graph with the same reference as that of the
probe/generator. Traces may be associated with the left or right axes in an analogue graph, and
probes/generators will add to the axis nearest the side they were dropped. Regardless of where
you drop the probe/generator, the new trace is always added at the bottom of any existing
traces.
The second and third method of adding probes/generators to a graph both use the Add Trace
command on the graph menu; this command always adds probes to the current graph (when
there is more than one graph, the current graph is the one currently selected on the Graph
menu).
If the Add Trace command is invoked without any tagged probes or generators, then the Add
Transient Trace dialogue form is displayed, and a probe can be selected from a list of all probes
in the design (including probes on other schematic sheets).
If there are tagged probes/generators, invoking the Add Trace command causes you to be
prompted to Quick Add the tagged probes to the current graph; selecting the 'Cancel' option
invokes the Add Transient Trace dialogue form as previously described. Selecting the 'OK'
option adds all tagged probes/generators to the current graph in alphabetical order.
