National Instruments 788101-01

The National Instruments 788101-01, also known as the PXIe-4190, is a sophisticated LCR meter and Source Measure Unit (SMU) designed for high-precision electronic testing and measurement. This module is essential for applications involving semiconductor components such as integrated passive devices (IPDs), microelectromechanical systems (MEMS), and multi-layer ceramic capacitors (MLCCs). The 788101-01 excels in capacitance-voltage (CV) and current-voltage (IV) automated test systems, making it a versatile tool for comprehensive electrical characterization.

The LCR meter functionality supports a wide range of measurements, covering capacitors from 100 fF to 5 mF with sensitivity down to 100 aF, inductors above 10 nH with a sensitivity of 10 pH, and resistors ranging from 100 mΩ to 1 GΩ with a remarkable sensitivity of 10 µΩ. The module operates over an AC stimulus frequency range of 40 Hz to 500 kHz, providing a maximum AC voltage of 7.07 V RMS and an AC current capacity of 70.7 mA RMS. Additionally, it is capable of applying DC bias voltages up to ±10 V and currents up to ±100 mA, ensuring detailed analysis in semiconductor testing.

The SMU function of the 788101-01 allows for precise voltage and current sourcing, with voltage ranges from 1 V to 40 V and current ranges from 1 nA to 100 mA. This feature is crucial for ensuring reliable input signals during device testing. The unit is designed for optimal noise performance, exhibiting wideband source noise below 20 mV peak-to-peak while supporting remote sensing to mitigate errors related to lead resistance and voltage drops.

Robust protective mechanisms are integrated into the 788101-01, including automatic output disable capabilities in scenarios of overvoltage, overcurrent, or overtemperature, thereby safeguarding both the device and the equipment under test. The module dimensions are 2.0 cm x 13.0 cm x 21.6 cm (0.8 in. x 5.1 in. x 8.5 in.), with a weight of 481 g (17.1 oz.). The 788101-01 adheres to rigorous environmental and safety standards and is recommended to have a calibration interval of one year for optimal performance. This product comes with a three-year warranty, reflecting the manufacturer National Instruments' commitment to quality and reliability.
