Programmable Digital Sequencer with 10ns Step Width for Fast and Precise Test Control

During measurements in testing laboratories often the test facility, the unit under test or both must be controlled in a specific timed sequence. This task can be solved easily with the SATURN Sequencer from AMOtronics. The Sequencer allows precise and synchronous control of switches, contactors, relays, IGBTs, MOSFETs etc.

The outputs of the SATURN Sequencer are being controlled via an internal clock of 10ns or in AC applications synchronized with the generator frequency (16 2/3Hz, 50/60 Hz, 400Hz etc.). The SATURN Sequencer offers 16, 32 or 64 digital connectors, which can be provided in groups of 8 either with BNC or fiber optic inputs or outputs. The fiber-optic connectors provide a fault-resistant insulation against high voltages and high currents. This allows the use in High Voltage and High Power Testing applications. In addition the signal transmission via fiber-optic cables also enables bridging of distances to the test facility or unit under test. Therefore the SATURN Sequencer is a perfect match for other safety-critical applications like explosion experiments and impact tests.

The program for controlling the outputs can be developed using a convenient graphical user interface within the Sequencer operating software. In addition to a pure sequential processing also loops and case statements (branches) are supported. After the program has been downloaded to the on-board FPGA (Field Programmable Gate Array) of the Sequencer, the program is executed in real-time independently from the operating system.

The Sequencer can be used either as a stand-alone device or integrated into a SATURN Transient Recorder. In the latter case analogue signals measured by the transient recorder can be monitored in the Sequencer and used to respond instantaneously to any event. Furthermore this setup allows recording of the Sequencer outputs in parallel to the measurement signals of the Transient Recorder. This enables in-depth synchronous inspection and analysis of control signals and measurement signals after the test.
