Application Overview
In test and research applications where one of the key measurement parameters is rapidly changing it is necessary to use instrumentation that can collect readings at a very high frequency.
For example if the position of an actuator arm is moving in and out at a frequency of 500 Hz, the position measurement device will need to measure in the order of x1000 Hz to provide enough readings to characterise how the position is changing during one full cycle of movement.
The frequency of response is typically limited by the sensing technology or the signal conditioning electronics, regardless of how fast either one is, the slowest one will always dictate the overall measurement response.
For example a very fast microprocessor combined with a slow reacting temperature probe, will provide lots of data points from the temperature probe. If the temperature changes faster than the response of the temperature probe then many of the data points will lag behind the actual temperatures at the time they were recorded or transmitted.
