Calculations

In the following example we will see how to do simple calculations in the Interpreter. The Schematic Editor will contain a basic RLC circuit.( e1.sch )

Run transient analysis with the given defaults. Click on the Tools menu and select the Interpreter. The Interpreter window appears.

Note: To insert these TINA screen views into this manual (a MicroSoft Word document), we used the PrintScreen key in TINA to copy the screen to the clipboard. You could also copy any windows of TINA to the clipboard by selecting the window and pressing the Alt+PrintScreen keys. Then we pasted the clipboard contents into this document.

i) Let’s first check R, one of the circuit parameters.

Write in the Interpreter

R = , Then press enter.

The Interpreter will give the result

R = [250] , That is 250 Ohm

ii) Calculate the impedance of the circuit at a radian frequency of 100k:

Write in the Interpreter,

R=[250]

w:=100k

Z:=R+Replus(j*w*L,1/(j*w*C))

Z=[250-20.0642*j]

Abs(Z)=[250.8039] { the absolute value }

Arc(Z)=[-80.0852m] { the phase value(radian) }

There are more functions available ( See the Appendix ).

To save these calculations, click the Save button on the toolbar, and follow the prompts. To recalculate results, press the Run button on the toolbar or use the Run menu.
