Programming of the DC output and the extensive protection features can be done either from the front panel or using industry standard SCPI commands via the GPIB. Using the serial link, up to 16 power supplies can be connected through one GPIB address. Test system integration can be further simplified by using the VXIplug+play drivers.
The output voltage and current can also be controlled with analog signals. This is helpful for certain types of noisy environments, and also immediate reactions to process changes.
The 6680A series has extremely low ripple and noise for a 5000 watt DC power supply.
