The National Instruments 788088-01 PXIe-4190 PXI LCR Meter is designed for precise measurement of inductance, capacitance, and resistance in electrical devices. This instrument operates with a maximum frequency of 2 MHz and provides sourcing and sinking output power of up to 4 W. It features a DC current range from 1 nA to 100 mA and supports a maximum DC voltage of 40 V, enhancing its versatility for various test and measurement applications. The AC voltage capability reaches up to 7.07 V RMS, while the maximum AC current is 70.7 mA RMS, ensuring accurate and reliable measurements. Measurement times can be set to short (1 ms), medium (10 ms), or long (100 ms), with options for user-defined custom durations to meet specific testing requirements.

Connectivity is streamlined through the instrument's front panel, which includes custom coaxial sockets alongside standard connectors and a mixed layout female D-SUB connection. The PXIe-4190 is engineered with robust protection features, such as automatic output disable responses to prevent overcurrent or overvoltage conditions. It is rated for absolute maximum voltages of ±42 V or ±6 V, further ensuring the safety of the device during operation. Compatible with both PXIe and Compact PCIe systems, the PXIe-4190 measures 2.0 cm x 13.0 cm x 21.6 cm (0.8 in. x 5.1 in. x 8.5 in) and weighs 481 g (17.1 oz). This product comes with a three-year warranty, reaffirming National Instruments' commitment to quality and reliability.
