PC-Ecap

PC-Ecap is a scientific program that targets users in need of an accurate circuit analyzer that can calculate a wide array of parameters based on user input.
PC-Ecap can work with AC circuits that consist of capacitors, resistors, inductors, transistors, transformers, as well as operational amplifiers.
It is suited for teachers, students and virtually any scientist that is dealing with circuit analysis, providing an essential toolset for evaluating an electronics project thoroughly.
Compared to similar applications, PC-Ecap may seem a little bit old fashioned, because of its console approach, but before making any assumptions, simply try it.
It doesn’t require an installation process, just launch the EXE file located inside the download archive and follow the on-screen instructions.
The main window provides access to the core of the program, displaying the steps you need to take in order to carry out a successful analysis operation.
Your first requirement is to select the input file, which has to be in DAT format and located inside the program’s folder. There is a collection of sample files wrapped up together with the program, which you can experiment with limitlessly.
In the second step, you can edit the parameters inside the input file, while the third step performs the circuit analysis. The output data can be visualized in the fifth stage or outputted to the printer in the final one.
The results will include calculations for gain, impedance, return loss, VSWR, phase and group delay, while the transient response of a circuit can be visualized using multiple waveform types.
The advantage of PC-Ecap is that it can handle up to 1000 components and is able to make complex computations at good speed. It could use a complete makeover, as far as its appearance is concerned.
