Tina can be kind of frustrating though since it’s a GUI application so for almost as long I’ve had this idea about finding some other simulator that can be scripted in some way to run a batch of simulations where I can do variants of each simulation. This work book will include: Work. ception of sweep variables, component values could only be numbers, for example R1 = 1k, and were not allowed to be represented by algebraic expressions like R1 = Value1, where Value1 = 100. 2 Mohm, which can alter the simulator waveforms. As with most things Linux the user manual is 'make it up as you go' but once you download a few examples and see how other people have done things it starts to get a lot easier. The LPF is enclosed in a die-cast aluminium box with BNC sockets for input and output. Note: Sweep Settings are not applied until either OK or Apply is pressed. , a frequency sweep with 20 points per decade from 0. Modelling high frequency components with RFEDD: high­frequency inductance example* *M. 20Hz to 20,000Hz is commonly considered to be the range of human hearing. The differences between the Qucs-S and Qucs Parameter sweep definitions are listed below.
