Main Unit

The main unit incorporates all necessary equipment for use with the eleven modular experiments modules. Power supply, function generator, and analogue and digital meters are all built-in.

The DC power supply provides fixed ±5V
and ±12V at 1A, a variable ±0V ~ ±25V
at 1A, and a transformer provides a
19V-15V-9V-0V-9V-15V-19V AC output
at up to 1A.

The function generator offers sine, square,
and triangle waveforms at frequencies from
10Hz ~ 1MHz in 6 ranges.
