1. .PRINT The result from dc analysis can be obtained in the form of table
Example:-print statement .PRINT DC (Output variables)
We will get output variables, maximum up to 8 values
2. .PLOT The result from dc analysis can also be obtained in the form of line printer plots. The plots are drawn by using characters, and the result can be obtained from any kind of printer.
Example:-plot statement .PLOT DC (Output variables) +
[{(Lower Limit) value}, (Upper limit) value}]
We will get output variables, maximum up to 8 values
The range and increment of the x-axis is fixed by the dc analysis command.
The range of the y-axis is set by adding [{(Lower Limit) value}, (Upper limit) value}]
At the end of the .PLOT statement .it can be placed in the middle of a set of o/p variables.
If the y-axis range is omitted, P Spice assigns a default range determined by the range of the output variables.
Example:-.PLOT statement .PLOT DC V(2) , V(3,5), V(R1), I(Vin) , I(R1)
3. .PROBE Probe is a Graphical wave form analyzer
Example statements:-
.PROBE where no output variables is specified, it writes all node voltages and all the element currents.
PROBE OUTPUT
.PROBE V(5),V(4,3), I(R2) where the output variables are specified ,PSpice writes only the specified out put variables to the PROBE .DAT file.
In the statement we have to write ‘m’ for milli not to write as MIL ;
M for mega , not to write as MEG
If a dc voltage source VS is connected between nodes 2 and 3,the plot of the trace(or curve) = V(2,3) * I(VS) will give the power delivered by the source VS
