8-channel & 4GHz high-resolution oscilloscope and digital PMIC,
Optimized for power supply and power integrity testing

Teledyne LeCroy (CEO: Woonjae Lee) announced the RP4030 active voltage rail probe and the industry's first serial decoder MIPI System Power Management Interface (SPMI).

The RP4030 probe measures small signal changes on a DC power/voltage rail, and the SPMI decoder can correlate and monitor DC power/voltage rail changes with SPMI serial bus messages.

These two products are ideal for reducing power consumption and increasing system efficiency in embedded system testing using line- or battery-powered computing and digital power management ICs (PMICs). They expand the capabilities already offered by Teledyne LeCroy's HDO8108 (1 GHz, 8-channel) and HDO9404 (4 GHz, 4-channel, 10-bit) high-resolution oscilloscopes.

The RP4030 offers a wide built-in offset range of ±30 V, a low attenuation factor of 1.2x, and a high DC input impedance of 50 kΩ. This combination of specifications allows the acquisition of a DC rail voltage from a DC power/voltage rail with an offset, centering the DC signal on the oscilloscope screen, and precisely viewing the noise and low AC fluctuations on the DC rail voltage signal at an oscilloscope gain setting such as 5 mV/div.

The probe has 4 GHz bandwidth (twice that of competing probes) and is ideally suited for power integrity testing with Teledyne LeCroy's HDO9404 High Definition Oscilloscope.

The RP4030 is available with a variety of tips and leads. It includes a 4GHz MCX Solder-in, a 3GHz U.FL Coax Cable, or a 4GHz U.FL Coax Cable, a U.FL PCB mount, and a standard 36” (914mm) SMA-MCX cable for connection to a 4GHz MCX solder-in lead. Tips with adjustable measurement point spacing are also available as an option.

The high bandwidth and extremely small size of the solder leads or U.FL PCB sockets (3mm x 3mm) allow for multiple tips and leads to be connected in tight spaces, such as in mobile/micro-portable and battery-powered systems. Additional sockets or leads are available as accessories, and keeping them connected to the circuit allows for quick and easy connection of various signals during subsequent test or validation stages.

Teledyne LeCroy's HDO9000 Series supports the RP4030 with firmware version 8.2.1.1, and it will be supported on all Teledyne LeCroy oscilloscopes starting January 2017.

Developers of mobile/microsystems and battery-powered systems use MIPI SPMI for communication between embedded system CPUs and power management ICs (PMICs). The goal is to maximize the performance of embedded systems by controlling power levels while maintaining the target system performance.

Teledyne LeCroy's SPMI decode option provides transparent, color-coded decode results over the captured SPMI physical layer waveform for easy understanding. SPMI protocol decode information is displayed simultaneously with other protocol data in a single interleaved table. Tapping on a column in the table quickly zooms into the selected protocol packet, and pattern searches and filters provide an easy way to identify desired protocol packets and messages.

SPMI decoder is multi-master/multi-slave capable, supports full command and arbitration sequences, and supports all sequences that include pauses.
