List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE. The following table is split into two groups based on whether it has a graphical visual interface or not.
The Tektronix model 575 curve tracer shown in the gallery was a typical early instrument. Nowadays, curve tracers are entirely solid state and are substantially automated to ease the workload of the operator, automatically capture data, and assure the safety of the curve tracer and the DUT. Recent developments in curve tracer systems now allow ...
Electronic test equipment is used to create signals and capture responses from electronic devices under test (DUTs). In this way, the proper operation of the DUT can be proven or faults in the device can be traced. Use of electronic test equipment is essential to any serious work on electronics systems.
Octopus is a software package for performing Kohn–Sham density functional theory (DFT) and time-dependent density functional theory (TDDFT) calculations. [ 1 ] Octopus employs pseudopotentials and real-space numerical grids to propagate the Kohn–Sham orbitals in real time under the influence of time-varying electromagnetic fields.

The programs include both open source and commercial software. Most of them are large, often containing several separate programs, and have been developed over many years. Most of them are large, often containing several separate programs, and have been developed over many years.
The tester has all these features and can check solid-state devices in and out of circuit. Transistor h fe varies fairly widely with Ic, so measurements with the service type tester give readings that can differ quite a bit from the h fe in the transistor's real life application.
Such applications include I-V characterizing and testing semiconductors and other non-linear devices and materials, where sourcing voltage and current source span across both positive and negative values. To accomplish this, SMUs have four-quadrant outputs. [1] For characterization purposes SMUs are bench instruments similar to a curve tracer.
