The MX0023A InfiniiMax RC is a new high-speed differential probing solution for Double Data Rate 5 (DDR5) and Low Power Double Data Rate 5 (LPDDR5) memory. As data rates of mobile bus systems increase, the edge speed of the signal gets faster, thus requiring higher bandwidth probe solutions. At the same time, many systems deploy […]
Basics of active and differential scope probes
By far the most used oscilloscope probes are the passive 10:1 attenuation probe. It is appropriate when the frequency of the signal under investigation is less than 600 MHz. Impedance matching from the probe tip to channel input port is critical. A mismatch gives rise to reflections, collisions and loss of data. At dc to […]
Probing Small Signals on a High-Voltage Bus
Subtleties of scope probes can lead to garbled measurements when examining power circuits. KEN JOHNSON, DAVID MALINIAK, TELEDYNE LECROY CORP. When an oscilloscope is used for debugging, validation, or device characterization, measurements generally take place with the help of a scope probe. There are several types of scope probes because manufacturers optimize different types for […]
Saelig to stock Teledyne LeCroy HVD3000A Series 1-6kV high-voltage differential probes
The Teledyne LeCroy HVD3000A High-voltage Differential Probes – the 1kV HVD310xA, the 2kV HVD3206A, and the 6kV HVD3605A — are now stocked by Saelig Co. Inc. These probes provide excellent CMRR over a broad frequency range to simplify the measurement challenges found in noisy, high common-mode power electronics environments. The probe’s design makes it easy […]
First 56-GBd optical probes for real-time scopes help troubleshoot 400G PAM4 components
The industry’s first 56 GBd 400G PAM4 optical probe is designed for use with Tektronix DPO70000SX Series real-time oscilloscopes. The new 59 GHz DPO7OE2 single-mode optical probe delivers the performance and advanced debug capabilities designers need to troubleshoot 400G PAM4 components and reduce time to market. Compared to 100G with NRZ modulation, 400G with PAM4 […]
