Page 4: Safety And Technical Support Information
There are no user serviceable parts in the PRC50. PRC50 units should be returned to the manufacturer for any repair. If the PRC50 is not used as prescribed by the manufacturer, the overall safety may be impaired. Disconnect electric power from the PC before installation or removal of the card. -

Page 6: General Description
Power to operate the card is drawn from the host PC. The PRC50 can be combined with A/D Boards or other signal detection and processing instrumentation, which gives system integrators the flexibility to optimize system cost and performance. -
Page 7: Prc50 System Blocks And Their Functions
Theory of Operation PRC50 System Blocks and Their Functions The PRC50 Pulser-Receiver Card is composed of the functional blocks shown in the figure below. These are the Control Logic and PCI interface, High Voltage Power supply, Pulser, Receiver Amplifier, Receiver Low Pass Filters, and Receiver High Pass Filters. JSR Instrument Control Panel software resides in the host computer and controls the instrument via the PCI interface. -
Page 8: Jsr Control Panel
PRC50 Pulser-Receiver Card JSR Control Panel This software enables a user to remotely control the PRC50 from a host computer. In addition to the JSR Control Panel program provided with the PRC50, SDK information is provided in this manual for users that wish to develop custom instrument control programs. -

The PRC50 allows independent gain control of the T/R and Through receiver signal paths. Setting the JSR Control Panel software to “T/R” mode enables the T/R signal path and allows the user to perform Transmit/Receive measurements. Selecting “Through” mode enables the Through signal path and allows the user to perform Through measurements. -
Page 10: Indicators And Connectors
Output Connector The PRC50 receiver output signal is present on this SMA connector. The PRC50 can provide an output signal of up to ± 1V into a 50Ω load. This output signal should be terminated with a 50Ω load to prevent reflections in any coaxial cable connected to this connector. -
Page 11: Trig/Sync Connector
In this mode, the signal line should be terminated with a 50Ω load. If the PRC50 pulser is set to external trigger mode, then the Trig/Sync connector is used for receiving a 3V to 5V external trigger pulse. Software controls select whether the Pulser will trigger on the rising edge or falling edge of the trigger pulse. -
Page 12: Instrument Setup
PRC50 Installation Do not install the PRC50 card until the JSR Instrument Control Panel software is installed. Note that Administrator privileges are required to install this software. It is recommended that only qualified personnel install the PRC50 card into the host computer. -

7. Remove the ‘blank’ slot cover from the back of the case by removing the screw that holds the cover in place. 8. Align the PRC50 with the slot and gently push the card into the connector on the computer motherboard. -
Page 14: Operation
Ultrasonic energy is echoed back from the test object and changes in time between echoes are taken as indications of variations in material continuity. To configure the PRC50 for T/R operation, the transmit/receive transducer is connected to the SMA connector labeled T/R, typically via a 50Ω coaxial cable. -
Page 15: Through Transmission Mode Operation
Through Transmission Mode Operation For Through transmission mode operation, separate transmitting and receiving transducers are employed. The transmitting transducer is connected to the PRC50 T/R SMA connector and the receiving transducer is connected to the THROUGH SMA connector. The PRC50 Through transmission mode configuration is shown below. -
Page 16: Simultaneous T/R And Through (Both) Mode Operation
For simultaneous T/R and Through (Both) mode operation, both transmitting and receiving transducers are employed. The transmitting transducer is connected to the PRC50 T/R SMA connector and the receiving transducer is connected to the THROUGH SMA connector. The PRC50 ‘Both’ mode configuration is shown below. -

6. Set the Trigger Source to ‘Internal’ or ‘External’ as applicable. • Set the Trigger Source to Internal if the PRC50 pulser is to be triggered by the PRF timing source. In addition, connect the PRC50 Trig/Sync connector to the external trigger input of the monitoring oscilloscope or waveform digitizer using a 50 SMA to BNC cable. -
Page 18: Jsr Control Panel
PRC50 Pulser-Receiver Card JSR Control Panel Please refer to the JSR Control Panel Operator Manual as found on the software CD that is included with the PRC50. This Windows-based control program should be installed on a PC running either the Windows 2000 or the Windows XP operating systems. -
Page 19: Program Control Of The Prc50
Communication between the control computer and PRC50 is via the PCI interface. For users who wish to create a Windows application to control the PRC50 a Software Developers Kit is included with the PRC50. Application software will use C or C++ calls to a provided DLL that will function with several JSR products. -
Page 20: Prc50 Default Values
It is important to note that the JSR Control Panel application always saves your most recent settings. When the PRC50 is restarted all of your saved control values except for Trigger Enable will be restored. Trigger Enable will always initialize to “Disabled”. -
Page 21: Prc50 Signal And Control Cables
In order to ensure solid connections and to minimize noise pickup, it is recommended that high quality coaxial cables and connectors be used. To connect the PRC50 card to a transducer (via T/R) or to multiple transducers (via T/R and THROUGH) the following cable is recommended: CBL-150 Transducer Cable This cable is 1.22 meters (4’) long and is manufactured using RG174/U Coaxial Cable with an... -
