PXIe-4147, 4-Channel, ±8 V, 3 A Precision PXIe Source Measure Unit
786888-01
Source Measure Unit
PXIe, 4-Channel, ±8 V, 3 A Precision PXI Source Measure Unit - The PXIe-4147 is a 4-channel source measure unit (SMU) ideal for high-pin-count applications. It features 4-quadrant operation, and each channel has integrated remote four-wire sensing for accurate measurements. The sample rate of the PXIe-4147 can reduce measurement times, capture transient device characteristics, and help you perform current-voltage (I-V) characterization of devices-under-test (DUTs). With a high-speed sequencing engine, you can synchronize SMUs with each other or with other instruments such as switches or high-speed digital test modules. Additionally, you can tune the PXIe-4147 response to any load to achieve optimum responses with maximum stability and minimum transients using SourceAdapt technology.

Measurement
Vibration Meter
-
The input signal of the Vibration meter software, which is the output signal of the accelerometer, i.e. the vibrational acceleration signal, is filtered by means of one of four possible digital band filters. Then, based on this signal, vibrational velocity and displacement signals are calculated by means of integrating filters. Thus, the software generates three signals which are transferred to the ZETLAB data server virtual channels created by the program and having the word “Acceleration”, “Speed” or “Displacement” in their names, respectively.Signals are averaged for a selected time interval (0.1 s, 1 s, or 10 s), after which the obtained values are displayed in the dialog box elements of the Vibration meter program. It is possible to display a root-mean-square (RMS), average amplitude or peak value.
