The TC840 CompactPCI time-to-digital converter module, with 50 ps timing resolution, is made for measuring the time of the rising or falling edge of very fast trigger events, using inputs with programmable thresholds. It is designed to handle large-scale experiments like hydrodynamics, particle accelerator timing, nuclear fusion studies and explosive testing, plus time-of-flight measurement in mass spectrometry and 3D mapping. With a wide-range, single- and multi-start converter, the TC840 uses 13 identical hardware channels: one is the common start, while the rest are independent stop inputs. It works in single-start or multi-start acquisition, and with timing information on all the independent channels encoded relative to the common channel. Up to 512 stops per channel can be recorded with the large internal buffer, and start/stop events up to 20 seconds apart can be recorded. Digitized data goes straight to the onboard FPGA-based data processing unit. This increases data throughout the PC through the direct memory access mode. The TC840 measures time on the internal low jitter (&3 ps rms), high stability (±2 ppm) clock source, or an external 10 MHz reference input. Pricing starts at $11,990, with delivery in six weeks ARO.
In many engineering workplaces, there’s a generational conflict between recent engineering graduates and older, more experienced engineers. However, a recent study published in the psychology journal Cognition suggests that both may have something to learn from another group: 4 year olds.
Conventional wisdom holds that MIT, Cal Tech, and Stanford are three of the country’s best undergraduate engineering schools. Unfortunately, when conventional wisdom visits the topic of best engineering schools, it too often leaves out some of the most distinguished programs that don’t happen to offer PhD-level degrees.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
