Solutions
Tektronix
Test equipment ‘Solution Bundles’ you need to perform Impedance, TDR, Bode Plots & PSRR, Converter Input Impedance and Power Inductor under bias measurements.
PDN Measurement forPower Integrity
The 2-Port Shunt-Through impedance measurement is the Gold Standard for PDN testing and Power Integrity assurance.
Measuring PCB, Cable and Interconnect Impedance, and Dielectric Constants
Picotest has a low-cost, pocket sized, signal edge generator and resistive port splitter that makes measurements with excellent accuracy.
Power Supply Rejection Ratio Measurement
PSRR is a significant performance concern as even small amounts of high frequency ripple voltage at the input can significantly degrade the output precision of voltage reference and impact downstream circuitry.
Non-invasive Stability Measurement
Control loop stability is critical to the performance of all systems, as it influences all closed loop parameters, as well as system noise.
Ultra-low Impedance (100 micro ohm and lower) Measurement Using 2-Port Shunt-Through
Measuring ultra-low impedance is a common requirement for assuring power integrity. This means measuring 1 milliohm to 2 milliohm voltage regulator modules (VRMs) and power distribution networks (PDNs).
Solutions for Rohde & Schwarz Equipment
Perform PDN, Bode Plot, PSRR, and NISM testing using Rohde & Schwarz oscilloscopes and Picotest Injectors.
Inductor Measurement Including DC Bias
The most important component in a switching power supply besides the power IC is its power inductor.
Input Impedance Measurement for DC-DC Converters
Testing the input impedance of a switching converter is a necessary step in designing a stable input filter to counterbalance the converter’s negative input resistance.
