DPS16 - Power supply module

DPS16: Dual channel Power Supply module

The DPS module is a 2 channel power supply with a programmable output voltage range of +/-12V at a maximum load of 200mA for each channel. In addition, the current and voltage at the output can be monitored. For PSRR measurements it is possible to generate a modulated voltage. For this purpose, the control block has a stimulus memory for each channel.
