-This repository holds [PSLab](https://pslab.io) hardware design files. PSLab is a tiny pocket science lab that provides an array of equipment for doing science and engineering experiments. It can function like an oscilloscope, waveform generator, frequency counter, programmable voltage and current source and also as a data logger. The first version of hardware (v1) was developed by [Jithin B P](https://github.com/jithinbp), a core developer of PSLab Project. Later versions were developed by [Padmal](https://github.com/CloudyPadmal).

 ## Feature list for the acquisition and control
 
 ### Oscilloscopes
 
-One of the main features of PSLab is the 4-channel oscilloscope which can monitor analog inputs at maximum of 2 million samples per second. It includes controls such as triggering, and gain selection. Uses Python-Scipy for curve fitting.
