Teledyne LeCroy Launches RP4030 Active Voltage Rail Probe and SPMI Decoder

Teledyne LeCroy launched two new products ¾ the RP4030 active voltage rail probe and an industry first MIPI System Power Management Interface (SPMI) serial decoder. The RP4030 probe measures small signal variations on a DC power/voltage rail, while the SPMI decoder monitors and correlates SPMI serial bus messages with DC power/voltage rail changes. These two products are ideal for testing line or battery-powered computing and embedded systems that use digital power management ICs (PMICs) to reduce power consumption and increase system efficiency.

What Are Good Connections to Evaluation Boards?

In many measurements, connections to the Device Under Test (DUT) is very important and can fundamentally determine whether the data we get is correct or not, whether the result is useful or potentially misleading.  This article highlights some of the main items to consider.  To illustrate the points, we use examples with DC-DC converter evaluation boards.

SIwave to Icepak Coupling


In today’s ever-changing PCB requirements arena, DC drop caused by IR losses are becoming a bigger concern for design engineers. Along with the IC currents demands increasing the currents carried on the PCB are rising as the voltages, and voltage margins, decrease. As the currents increase so do the heating effects of IR drop and their consequences to the PCB design. SIwave introduces a new solver type for design engineers to investigate preliminary thermal performance on designs.
