Electronics Manufacturing

A 2-port shunt-through setup with the Bode 100 uses Gain/Phase mode, a 50 Ohm termination on Ch2, Thru calibration, and a logarithmic sweep to read impedance and estimate inductance.

PDN measurement commonly relies on a vector network analyzer. The source distinguishes 1-port measurement for higher impedance from 2-port shunt-through measurement for very low impedance, while noting that instrument cost can affect the approach.

An FRA is commonly used for transfer functions and power-supply control loops. A VNA provides port-based S-parameter, reflection, and calibrated impedance measurements for more complex RF and interconnect work.

A vector network analyzer can help characterize passive components, but measurement accuracy depends on the impedance range and method used. A grounded-end approach with port extension and an R + jX marker may have significant error outside a narrow range.

The Bosch GLM laser distance meter series has long been a staple on construction sites and in manufacturing workshops. Mastering these hidden features optimizes construction schedules and significantly reduces manual operational errors.

A 2-port probe can measure PCB power-rail impedance with minimal board changes. For the VDD_3V3_S0 example, ON-state impedance was checked against an approximately 8 mΩ target through 7 kHz.

The 2-port shunt-through technique is used for milliohm impedance measurements at very high frequencies. Ground loops from instrument grounds and test cabling can introduce major error; the Picotest J2102A is used as a ground-loop breaker for measurements down to 20 micro-ohms.

Power-hungry AI accelerators and other high-performance chips increase the relevance of power integrity testing. Key topics include voltage regulator modules, PDN impedance measurement, and reducing the effect of probe ground-loop resistance with a low-noise isolator.

Choosing the right laser distance meter for your industry helps optimize work efficiency, reduce costs, and ensure measurement accuracy.

Laser distance meters typically achieve millimeter-level accuracy indoors, but errors immediately appear when used on a blazing construction site. The root of the issue lies deep within the physical and optical mechanisms operating inside the device
