+===== Features List =====
+==== Oscilloscopes ====
+{{ :offen:pinout_pslabv6.png?400|}}
+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.
+==== Waveform Generators ====
+  * SI1 : 5 Hz – 5 KHz arbitrary waveform generator. Manual amplitude control up to +/-3 Volts
+  * SI2 : 5 Hz – 5 KHz arbitrary waveform generator. Amplitude of +/-3 Volts. Attenuable via software
+  * SQx : There are four phase correlated PWM outputs with maximum frequency 32 MHz, 15 nano second duty cycle, and phase difference control.
+==== Measurement Functions ====
+  * Frequency counter tested up to 16 MHz.
+  * Capacitance Measurement. pF to uF range
+  * PSLab has several 12-bit analog inputs (function as voltmeters) with programmable gains, and maximum ranges varying from +/-5 mV to +/-16 V.
+==== Voltage and Current Sources ====
+  * 12-bit Constant Current source. Maximum current 3.3 mA (subject to load resistance).
+  * PSLab has three 12-bit Programmable voltage sources +/-3.3 V,+/-5 V,0-3 V. (PV1, PV2, PV3) controls
+==== Other useful tools ====
+  * 4MHz, 4-channel Logic analyzer with 15 nS resolution.Voltage and Current Sources
+  * SPI, I2C, UART outputs
+  * Graphical Interfaces for Oscilloscope, Logic Analyser, streaming data, wireless acquisition and several experiments developed that use a common framework which drastically reduces code required to incorporate control and plotting widgets.
+  * PSLab also has space for an ESP-12 module for WiFi access with access point/ station mode.
