The three main differences between the 2001+ and 2001 Lite are:

1) Lite does not have a separate menu for electroporation only - It can be used for that but it is not set up separately

2) Lite does not have pre-programmed protocols

3) Lite programs are only designed as [AC pulse-DC pulse-AC pulse] whereas the 2001+ can be programmed with up to 19 different AC steps with one DC step

Both the Lite and the 2001+ have the same generator specs:

For AC wave: Sine wave, 0.2-2MHz, 5-75 V peak, constant or linear ramping available, duration 0-99 s

For DC pulse: 5-3000V, 10 ms-999 ms
