A photon Doppler velocimeter can accurately measure the velocity of materials subjected to impact events. PDV analysis was initially developed to better understand the high - energy physics related to explosive events. It continues to evolve and has great potential to advance the research on dynamic compression and impact physics.
The events analyzed using a PDV system are usually “single - shot” events. Often, many laser channels and other sensor types are acquired to fully understand the experimental response. High - fidelity acquisition of low - amplitude signals is crucial for the quality of experimental results.
Since PDV experiments can be very expensive, and sometimes the cost of a single test exceeds several million US dollars, a highly reliable signal acquisition system with excellent signal fidelity is of utmost importance. Tektronix has a long - standing history of providing excellent signal fidelity in single - shot acquisition and has the sampling rate and bandwidth required to correctly represent the detected events. You can rely on its performance.
Tektronix DPO70E products provide calibrated O/E (Optical to Electrical conversion). It is an ideal detector used in front of the DPO70000SX or DPO70000DX oscilloscopes that perform digitization functions. This combination offers a high number of channel options, extremely accurate and stable acquisition timing, an acquisition rate of up to 200 GS/s, and bandwidths of 33 GHz and 59 GHz to support the fastest air - gun experiments, as well as an excellent SNR (Signal - to - Noise Ratio) to provide the best results in high - speed event analysis.
As researchers attempt to learn more about each event, the number of channels on PDV systems keeps increasing. Multiplexed (MPDV) systems are now commonly used to pack more data into a single digitizer channel and minimize the space occupied by the digitizer system. Compared with traditional benchtop oscilloscopes, the Tektronix DPO70000SX device provides the same number of digitizer channels, with a bandwidth of up to 70 GHz, and occupies approximately only half the rack space (4U).
Monitoring a PDV system to verify key shots may require hundreds of sensors and precision acquisition hardware. The 5 Series MSO thin oscilloscope provides a next - generation high - performance 12 - bit digitizer. It offers high channel density in a rack - mountable installation that is easy to stack, and can achieve 100 synchronous channels within 350 ps. These 12 - bit digitizers have an adjustable front - end, support a hardware sensitivity as low as 1 mV/div, and provide all the other advantages of a standard high - performance oscilloscope. Expand the diagnostic monitoring capabilities of your PDV system while saving laboratory space and budget.
