Recently we have delivered an new control software to iseg. The software is called iseg THQ controls and as the name suggests, is has been designed to control iseg THQ modules. The software can be downloaded from the support -> downloads page of the iseg website. The below video gives…
Recently we have worked with Stefan Schippers from XSchem to interface BeSpice Wave with XSchem. XSchem is an open source schematic editor. BeSpice Wave is our graphical waveform viewer. This solution allows to visualize simulation results for SPICE simulations from XSchem. If you are looking for a waveform viewer for…
When Cadence Spectre performs a simulation, it writes all simulation results to a directory. This directory can be opened for exploring the simulation results. By default these files are in PSF or PSFXL format. Here we will give a short overview on the PSF and PSFXL file structure. The most…
Analog regression testing is an essential part of analog design verification. Regression test are used to validate analog behavioral models. They also make sure that a previouslytested analog block still performs as expected after a change. Once analog regression tests have been set up, they can also facilitate other tasks:…
The algorithms used for analog waveform comparisons can be straightforward. You can simply traverse all curves in a file and find the matching curve in a reference file. Now compute the difference between 2 curves and integrate the result to obtain the absolute error. Dividing this by the norm of…
Our waveform parser makes reading PSF files from Python easy. For this purpose we have extended our parser library to a self-contained Python module. This module is implemented as a C/C++ extension to Python. As a consequence you get the full performance of a C/C++ library and the ease of…
Physical Instruments has published a video on current measurement accuracy for high voltage power supply modules. The video shows how to make sure your high voltage power supply matches even the tightest specifications. In general checking the data sheet should be sufficient. However if you are in doubt, you can…
We have released a tutorial video that shows how to work with the graph window integrated to Easy LV|HV. The graph window allows to follow the measured quantities over time and detect anomalies such as arcs or excessive currents and temperatures. Hopefully the video is clear by itself. If not,…
Physical Instruments has published a video that will walk you through the first steps of using Easy LV|HV for controlling WI-EN-ER MPOD crates and Iseg iCS servers. Many hard- and software related aspects are handled. The highlights are: configuring your MPOD-C controller using MuseControl. using sense lines for WI-EN-ER low…
Physical Instruments has published a video on ripple and noise for high voltage modules. The video shows how to make sure your high voltage power supply matches even the tightest specifications. In general checking the data sheet should be sufficient. However if you are in doubt, you can easily measure…
