The Astronics / EADS / Racal 6063-4 is a 4-channel high-power precision source engineered for demanding aerospace, defense, and industrial test environments. This VXI-based instrument delivers independent control over four isolated output channels, each rated at 40V and 300mA. Channels support series connection for up to 160V or parallel configuration reaching 1A total current. The unit operates in constant voltage or constant current modes with 16-bit resolution per channel across three selectable voltage ranges—unipolar or bipolar. SCPI-compatible programming enables precise, repeatable output control at data rates exceeding 10 values per second per channel.
