Waveform Generator

The Waveform Generator has been designed to produce pulses, ramps, as well as triangular and sinusoidal signals that can be sent to a potentiostat to faciliate various electrochemical experiments.

Unlike most other function generators, a triangular waveform can be started anywhere between its upper and lower limits. Also the ramp can be paused at its instantaneous value or reversed by manual interaction, much as could be done with old style analog potentiostats, when characterising a new compound.

Highly stable low speed ramps are particularly useful for corrosion experiments, or solid state electrochemistry.

The unit is compatible with eDAQ e-corder and Chart software

When connected directly to a computer USB port (or via a USB hub) the unit and appears on a virtual serial port (COM3, COM4, etc). It now acts as a programmable ramp/pulse generator, using a serial protocol compatible with LabVIEW, HyperTerminal, or your own user-written software.


  • Output signal:  ±10 V maximum
  • Waveforms: DC sequences, pulses, ramp, triangular, sine
  • Sweep rates:  < 1 mV/h to 1 V/s (0.1 mV steps) or to 10 V/s (1 mV steps)
  • Minimum time increment: 100 μs
  • Minimum potential increment: 5 μV
  • Manual controls: Start/Stop, Pause/Resume, Reverse
