The LCR Reader MPB from Siborg Systems Inc. is a 36 g tweezers style LCR/multimeter that brings benchtop grade measurement performance into aerospace and defense maintenance, repair, and overhaul (MRO). It closes the gap between large, expensive benchtop LCR meters and traditional handheld instruments that lack the precision, frequency range, connectivity, and calibration traceability required for mission critical electronics.

Modern aerospace and defense systems use dense SMT assemblies with sub 1 pF capacitors, sub 10 nH inductors, and very small component packages on multilayer PCBs. Conventional benchtop LCR meters can characterize these components accurately, but they are not practical for line maintenance, hangar work, or field service. Handheld meters solve the mobility problem but often struggle with very low values, higher test frequencies, and stable contact on tiny SMD parts. Many portable tools also fall short of the calibration and documentation standards required in ISO/AS certified labs and military depots, and typically offer little integration with digital maintenance systems or automated test stands.

LCR Reader MPB addresses these issues by combining a 0.1% basic accuracy measurement engine with test frequencies from 100 Hz up to 250 kHz at 1 Vrms. This enables precise characterization of small reactive components in avionics, radar, electronic warfare, and high reliability control electronics. Gold plated tweezers tips allow direct contact with 0201 size components and fine pitch pads, reducing errors associated with traditional probes and clips. The instrument automatically identifies components (L, C, R) and selects optimal test parameters, while still allowing manual control when required.

Beyond LCR measurement, the MPB operates as an all in one digital multimeter, adding ESR, AC/DC voltage and current, frequency, duty cycle, LED/diode test, a simple oscilloscope style display for live circuits, and a built in signal generator. This reduces the number of instruments needed at each bench or in each field kit.

For board level diagnostics, the device supports Analog Signature Analysis (ASA), allowing technicians to compare I V signatures between known good and suspect boards to localize faults without removing individual components.

Connectivity is another differentiator. An optional Bluetooth configuration (LCR Reader BT) streams measurements into PCs and custom applications for logging and automated pass/fail checks. CAN protocol output integrates with PLC based test stands and automated MRO rigs, aligning with digital MRO and Industry 4.0 initiatives.

Every LCR Reader MPB ships with a NIST traceable Calibration Certificate, enabling use in calibration controlled aerospace and defense environments. Typical applications include avionics and flight control maintenance, radar and EW module repair, depot level diagnostics, production and rework in aerospace electronics manufacturing, and field service at remote bases. Compared with traditional approaches, the MPB offers faster troubleshooting, reduced dependence on fixed benchtop equipment, improved measurement integrity, and a lower total cost of ownership.
