PRC50 Pulser-Receiver Card
Description
The PRC50 Pulser-Receiver Card is a versatile single-channel ultrasonic pulser-receiver on a half-length
PCI card for use in a host computer. All card functions and configurations are under the control of the
host computer. A Windows-based turnkey control software program is provided to enable you to control
the PRC50. Alternatively, programming information supplied in this manual and in the included Software
Developers Kit (SDK) and Programmer’s Manual allows you to develop custom software programs for
controlling the PRC50.
In a typical application, the PRC50 produces a high voltage electrical excitation pulse, which is available
on the card’s T/R connector. Seven discrete pulse energy levels and a variable power supply are
available for adjusting the strength of this excitation pulse to the transducer. An ultrasonic transducer is
connected to the T/R connector via a length of 50Ω coaxial cable, and the transducer converts energy
from the electrical excitation pulse into an ultrasonic pulse that is propagated into a test material or
medium. Eight discrete damping levels in the PRC50 allow the transducer response to be fine-tuned.
With the PCR50 configured for Transmit/Receive mode of operation, any acoustic echoes reflected from
interfaces or from defects within the test material are converted by the transducer into an electrical signal
to be processed by the PRC50 receiver. This electrical signal passes through a user-adjustable gain
stage and the amplified signal then passes through adjustable high and low pass filters. After filtering, the
processed signal is available at the Output connector. The use of a second receiving transducer enables
the detection of ultrasonic pulses that propagate through the test material or medium. This second
transducer is connected to the PRC50 receiver using the THROUGH connector on the card, and the
received signal is processed as it is for transmit/receive mode operation.
The wide-bandwidth low-noise PRC50 receiver has inputs for T/R (Transmit/Receive) and Through
transducer signals. The receiver can amplify either input signal while maintaining excellent isolation from
the other signal. In addition, the PRC50 receiver can independently amplify both input signals, and output
the sum of the amplified signals. Following amplification, the receiver output signal passes through
selectable High-Pass and Low-Pass filters. The output signal is then provided on the PRC50 Output
connector.
The PRC50 is ideal for use in PC-based ultrasonic testing and inspection systems, and its small size and
low power consumption enable systems to be implemented using portable computers. 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. Connections are easily made between the PRC50 and other hardware using 50W
coaxial cables. The four interface connectors on the PRC50 are SMA female coaxial connectors. The
PRC50 Pulser synchronizes easily to other system hardware by producing or accepting trigger pulses on
the PRC50 Trig/Sync connector.
The full-featured PRC50 is an excellent choice for PC-based ultrasonic system applications including flaw
detection, quality assurance, material characterization, transducer testing, and time of flight
measurements.

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.
Control Logic and PCI Interface
The interface and control logic enables the control of the PRC50 from software running on the
host computer. Communication is via the PCI bus within the host computer.
High Voltage Power Supply
The high voltage supply provides power to the pulser. The PRC50 pulser produces constant pulse
amplitude regardless of the pulse repetition rate or other instrument parameters within the
specified range of PRC50 operation. The JSR Control Panel software and SDK software provide
“power limit status” indications that warn the user when the PRC50 Pulser may be operating
outside of the normal range of operation.
Pulser/ Energy/Damping
The pulser generates a transducer excitation pulse upon receipt of a trigger event from a selected
source. The Pulser Energy, Voltage and Damping controls control pulser parameters such as
pulse duration, energy and peak amplitude. There are seven energy and eight damping
impedance values provided by the PRC50. The Voltage Control is adjustable in 1V steps from
100 to 475 Volts.
Receiver Amplifier
Controls the amplification of signals presented to the PRC50 receiver. The receiver gain can be
varied from -14 dB to +60 dB. The PRC50 Receiver has an input impedance of 128Ω.
Low Pass Filters
This filter is available for reducing the bandwidth of the PRC50 receiver. High frequency
bandwidth limiting can be used to improve the signal to noise ratio for applications that do not
require the full receiver bandwidth. Four user selectable low pass filter values are available.
High Pass Filters
This filter is available for eliminating undesirable low frequency energy from the PRC50 receiver
signal. High pass filtering can be used as a means of providing faster receiver recovery from
strong signals such as the excitation pulse or strong interface echoes. Four user selectable high
pass filter values are available.

The transmit/receive transducer is connected to this SMA connector during T/R mode operation. A
transmitting transducer is connected to this connector during Through mode operation.
Page 10
JSR Ultrasonics, A Division of Imaginant
PRC50 Pulser-Receiver Card
Trig/Sync Connector
This connector provides a positive polarity sync pulse signal that can be used to trigger an oscilloscope or
other signal monitoring/recording instrument when the PRC50 internal oscillator is used to trigger the
pulser. 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.
When triggering the PRC50 pulser from an external source or under software control, it is important to
ensure that the average pulse repetition frequency does not exceed the 5 kHz maximum PRF rate.
Pulse Indicator (Pulse)
This red LED illuminates whenever the pulser is firing. This indicator may be cycled to create a blinking
indicator. The Pulse Indicator is located on the PRC50 card below the Trig/Sync connector.
