For the DL850 G3 Frequency Function, you will need to set the hysterisis of the edges that are used to detect the periods. This will increase the tolerance for noise and improve measurement reliability.
To configure the hysteresis for the frequency function on the DL850, follow the procedures listed below.
Please download and view the attached images to view the different effects of hysteresis on signal quality.
Data acquisition (DAQ) is the measurement, recording, analyzing, and presentation of real world phenomena. It includes electrical measurements such as voltage, current, power as well as measurements through sensors and transducers including temperature, pressure, strain, vibration, and more.
Yokogawa high speed data acquisition systems deliver industry leading isolation, bit resolution, sampling rate, and memory depth, with independent channel hardware and easy to use software.
Oscilloscopes are a common type of test instrument used to capture, analyze, and troubleshoot electrical or real world physical signals. Oscilloscopes observe the change of electrical signals over time, continuously graphed on a display as voltage or amplitude vs. time.
A ScopeCorder is an instrument combining a mixed signal oscilloscope and portable data acquisition recorder into a modular platform designed to capture both high-speed transients and low speed trends. Yokogawa’s ScopeCorder product family provides flexible and high-performance multi-channel test instruments by combining a variety of signal conditioning input modules, on-board calculations, and deep data acquisition storage into a off-the-shelf data acquisition solution.
