The Effects of Passive Probe Ground Leads
This article explains how the inductance of passive probe ground leads can dramatically reduce effective bandwidth, distort measurements, and introduce resonance and frequency-response errors.
This article explains how the oscilloscope Trend function differs from Track, and how it can be used for long-term measurement analysis, data logging, and monitoring evolving signal behavior across multiple acquisitions.
This article explains how the oscilloscope Track function can be used for anomaly detection and waveform demodulation by graphing synchronized measurement values directly against the input waveform.
This article explains how to properly configure an oscilloscope for ESD pulse testing, covering rise-time thresholds, EMC pulse measurements, parameter limiting, and automated trend capture for compliance testing.
This article explains how to properly configure an oscilloscope for EFT testing, covering sample rates, parameter acceptance, EMC pulse measurements, energy calculations, and efficient burst acquisition techniques.
This article explains how to properly configure an oscilloscope for surge testing, including attenuation setup, measurement threshold adjustments, and calculating pulse area and transferred charge.
Virtual probing techniques can eliminate reflections in mid-bus DDR measurements, delivering cleaner signals and more accurate analysis.
Accurate ESD pulse measurement depends on using a high enough sampling rate to capture sufficient points on the rising edge for reliable characterization.
Standard IEEE pulse definitions can misinterpret fast-decaying ESD pulses, requiring manual threshold adjustments for accurate measurements.
Accurate EMC/ESD testing begins with verifying surge and ESD pulse characteristics—such as rise time and bandwidth—using high-speed oscilloscopes before applying them to the DUT.
These nine practical DDR probing tips help reduce strain, improve signal integrity, and avoid common measurement pitfalls when working with high-speed DRAM interfaces.
