Finite rise times arise from the inability of a rheometer to instantly apply the desired strain to a material.
These SDLVAs offer fast 25 ns rise times and 30 ns fall times.
The programmer uses high-speed bipolar analog pin drivers with microstrip transmission lines to deliver 800 ps rise times at the programming socket without overshoot or ground bounce.
Temperature rise times are more precise and quicker, resulting in significant timesaving in the lab.
LVD SCSI is a low voltage differential signal with fast rise times. The total SPI-2 and SPI-3 budget for differential crosstalk and noise, per the standards, is 55-60 mV.
DC voltage and DC current sources have slow rise times that settle to a stable current level and need test times from 10ms or more.
They showed that the rise times of the synaptic inputs coming from the two ears occur at different speeds: the rise time of messages coming from the ipsilateral ear are faster than those driven by the contralateral ear (the brain has two groups of neurons that compute this task, one group in each brain hemisphere-ipsilateral messages come from the same-side ear and the contralateral messages come from opposite-side ear).
The main peak rise times follow a smooth curve, ending at 0.85 [micro]s for zero nominal source rise time.
As rise times shorten, it becomes vitally important to know how to achieve and maintain good signal integrity, including crosstalk, reflections, termination, placement and routing.
