Selecting a Sample Rate for Measurement Systems

The choice of a channel’s sampling rate (number of measurements per second, or simply the sampling frequency) may determine whether or not a measurement returns useful results. If data are sampled at too high a rate, the measurement results may be useful, but the amount of data accumulated is unnecessarily high, wasting memory or storage, (10.04.2009)

Synchronized versus Sequential Sampling Methods for Measurement Systems

How does one select the right measurement system structure for a given measurement task? Should channels be sampled simultaneously, in synchronization, or is it sufficient for the channels to be sampled sequentially using an analog multiplexer? (25.06.2007)

Determining the Uncertainty of Measurement Results
with Multiple Measurement Quantities

To determine the uncertainty in the results of a single-channel measurement, one must consider the contributions from both the sensor’s uncertainty and the uncertainty of the measurement channel. (25.06.2007)

Why Do Measurement Systems Need Sample & Hold Amplifiers?

Sample & Hold amplifiers are to digitizing measurement devices a bit like vitamins are to humans; they are noticeable in their absence, which can spell serious trouble. This white paper aims to illustrate the functioning and usefulness of these components (26.06.2007)

Estimating Parameters of DC-Motors

DC-motors are used in a wide variety of applications touching our daily lives, where they serve to relieve us of much work. However, the large number of DC-motors used is attended by a large amount of time and re-sources devoted to inspecting them at the end of their production cycle. The time needed for this process should be kept as... (23.07.2007)

EtherCAT - The new standard

EtherCAT for measurement engineering is a hot topic of the day - and rightly so. That's because this Ethernet-based Field bus, with its extremely short cycle periods and its precise synchronization is equal to even the most demanding real-time requirements. (09.12.2009)

Voltage measurements of hybrid engines

Hybrid engines are gaining increasing importance in the automotive world. This kind of propulsion compromises both a conventional internal combustion engine and an electric motor. The power supply for the electromotor and the energy recovery from the braking process involve batteries which can typically have voltages of many hundred Volts. (23.06.2009)
