| − | This is a very handy software solution, available over the official Apple App Store for a symbolic price of approx. just 1 € while the solution is very fast and has many interesting options including the XY mode. The default controls with the round knobs are a bit tricky to use (turned in a circle) but can be replaced with sliders in the configuration.

| − | It is a dual channel oscilloscope software with XY mode as well and has an inbuild signal generator for use with audio outputs or also as input channel. Oscilloppoi works very well in the frequency range of 20 Hz up to 20 kHz while showing some distortions in the sine waves at more than 10 kHz. This is related to the maximum sampling rate of 48 kHz on the audio channel. The software has no voltage shown on Y axis but using the scale factor 4.5x is showing a signal with approx. 5V/div.

| − | A software solution for Windows user is the Soundcard Oscilloscope from Christian Zeitnitz which is free of charge for private use. The software runs under several WIN versions like 7/8/10 and was very stable during tests. A calibration factor of 2.5 in the settings gives an approx. good result of the input signal of 1V amplitude.

| − | The software supports dual channel display including XY mode and has also an inbuild signal generator. Additionally this software has a feature of FFT to show the Fourier spectrum of a signal.

| − | There was a small issue with the audio input device we used. WIN 10 recognized this as a mono device (microphone) only while it supports stereo line in. This issues can be solved in the WIN configuration, selecting your audio input device and set the configuration option to Stereo with 48 kHz Sampling frequency.
