OPCARD 2.2 PCI-bus Ultrasonic Card with Integrated Pulser and Receiver
2Pages

OPCARD 2.2 is a complete ultrasonic testing device, suitable for all ultrasonic measurements and due to many additional digital inputs/outputs and internal processor it can be used as a controller for more complicated devices. The card can work together with devices like multiplexers or scanners. Opcard can work in sequence mode. It has possibility to store up to 1024 sets of settings. So parameters can be switched very fast for every next data acquisition. The system allows to buffer many acquisitions in internal memory and forward whole packet of data to control application. In this way, the high throughput of data reading from the device is obtained. The card has an implemented one channel pulser & receiver and can be used with one or with two transducers (one is sending, and the second one receiving).
