OPCARD 2.0 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 following devices: ■ 32 channel multiplexer - the card can control it directly; ■ Scanner - it has input for incremental encoders; The card has an implemented one channel pulser & receiver and can be used with one transducer or with two (one is sending, and the second one receiving). Technical Data -Low noise preamplifier (0.74 nV/V(Hz)) -High gain up to +92 dB -Switchable analog filters -Support fast TGC (time gain compensation) -2 signal inputs PE and TT -Input attenuator (-20dB) -Input Impedance 50 Ohm, 10pF -100MHz sampling frequency, 10bit resolution -Up to 512k x 16bit samples memory -Delay settings up to 65535 sample periods -various triggering mode -Data transfer speed - up to 132MB/s -Expansion Connector for extra functions daughter-board -interfaces (RS232, RS485, SPI, I2C) -Standard PCI short card (174.63mm x 106.68mm) -BNC or Lemo analog connectors -DB15 connector for I/O and power lines Analog parameters: Input Amplifier Gain: Input PostAmplifier: Input Attenuator: Input Range: Full Bandwidth: Przedsi^biorstwo Badawczo-Produkcyjne OPTEL Sp. z o.o. ul.
