Page 8: Theory Of Operation
5 Theory of Operation 5.1 DPR300 Subsystems and Their Functions The DPR300 pulser/receiver is composed of the functional blocks shown in the figure below. These functional blocks include the front panel and remote control hardware, high voltage power supply, pulser, pulser trigger select, PRF oscillator, receiver amplifier, receiver low pass filters, receiver high pass filters, and the RS-232 interface for instruments with the remote PC control option. - Page 9 Controls the amplification or attenuation of signals processed by the DPR300 receiver. The receiver gain can be varied from -13 dB to +66 dB. The DPR300 receiver has an input impedance of 500 ohms and is available in both 35MHz and 50MHz bandwidths.
- Page 10 These filters are available for eliminating undesirable low frequency energy from the DPR300 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.

6.1.2 Power Indicator LED (Power) An amber-colored LED that lights to indicate that power is applied to the DPR300. This LED can also be made to blink at a controlled rate by the ‘Blink’ command described in Section 6. 6.1.3 Pulse Indicator LED (Pulse) This is a red LED indicator that illuminates when the DPR300 pulser is firing. - Page 12 中国代理商-长沙鹏翔电子科技有限公司 6.1.4 PRF Control A rotary switch that selects the frequency at which the pulser fires when internal trigger operation is selected. The PRF values range from 100 Hz to 5 kHz. 6.1.5 Int / Ext Switch A toggle switch that selects between internal trigger (PRF) and external trigger sources for the pulser.
- Page 13 6.1.15 Receiver Output Connector (Receiver Output) This connector is a BNC receptacle on which the output signal from the DPR300 receiver is available. This output signal line should be terminated with a 50 Ω load. 6.1.16...
- Page 14 中国代理商-长沙鹏翔电子科技有限公司 If the DPR300 pulser is operated in external trigger mode, then the Trig / Sync connector is used for receiving a positive going 3V to 5 V external trigger pulse. Triggering of the pulser will occur synchronously with the rising edge of the trigger pulse.

8.2 Transmission Mode Operation For transmission mode operation, separate transmitting and receiving transducers are employed. The transmitting transducer is connected to the DPR300 T/R connector and the receiving transducer is connected to the Through BNC connector. The DPR300 transmission mode configuration is shown in the next figure. -

PC or other computer. Otherwise use the front panel controls to control the instrument. 4. Set the pulse trigger control to INT if the DPR300 pulser is to be triggered by the internal PRF oscillator, and connect the DPR300 Trig/Sync connector to the external trigger input of the monitoring oscilloscope. - Page 18 中国代理商-长沙鹏翔电子科技有限公司 pulse repetition frequency (PRF) should be adjusted such that all echoes from any previous excitation pulses have subsided before a new excitation pulse is generated. 6. Adjust the gain control to obtain a signal level between ± .2 and ± .5 Volts peak into a 50 Ω load at the SIG OUT connector.
