Power Integrity - Precise measurements with the R&S®RTE1000 Oscilloscope and the R&S®RT-ZPR20 Power Rail Probe
The quality of the power supply is a key factor in the functionality and performance of sensitive electronic circuits. Disturbance signals on the DC power supply network can lead to EMC problems or impair the functioning of a circuit. To assess the quality of the power supply for such components, Rohde & Schwarz offers the R&S®RT-ZPR20 power rail probe. It is designed for precise power integrity measurements in combination with the R&S®RTE1000 and R&S® RTO2000 oscilloscopes.
Power Integrity - 5 tips on how to make more precise measurements
Making accurate power integrity measurements continues to increase in importance as rail voltages get lower and tolerance get tighter. Most important for precise results is a low noise oscilloscope and the right probe. This video demonstrates how to obtain the best results using the R&S®RTE1000 oscilloscope and the R&S®RT-ZPR20 power rail probe.
Meeting EMI and EMC requirements is critical to bringing electronic products to market. Compliance testing requires expensive equipment and test time at a compliance laboratory. Failures found late impact project costs and launch schedule due to debugging and re-testing. This video shows how the R&S®RTO oscilloscope can be used with a near field probe to find and fix EMI issues quickly and reliably during the development at the R&D lab thereby minimizing expensive re-testing and shortening time to market.
Testing Conducted Emission in the R&D lab
Conducted emissions are electromagnetic disturbances caused by a device and conducted out by interconnects such as the power supply lines. Devices are required to pass stringent limits on the level of such emissions and these tests require expensive testing time at compliance laboratories. This video shows how the powerful spectrum analysis features in the R&S®RTO oscilloscope can be used to verify conducted emission levels relative to the requirements during development thereby ensuring passing results in the compliance laboratory.
Capturing of intermittent RF signals with the Zone Trigger
Zone Triggering typically allows to define a trigger condition based on an area of voltage and time. The R&S®RTO oscilloscope features a very powerful extension and offers Zone Triggering also in the Frequency domain. This is useful for triggering for example on EMI interferences or other frequency domain effects. This video demonstrates this unique capability of the R&S®RTO on the example of a frequency hopping signal.
Measurement of very small currents
Measuring small currents has become increasingly important for battery powered portable and wearable consumer devices, IoT and medical applications. Designers of these devices must measure currents from the sub-milliampere up to the ampere range. The R&S®RTE and R&S®RTO oscilloscopes can measure currents down to 100 uA using their low noise and high-sensitivity current probe.
Power Integrity Test
Today’s highly integrated electronic devices use smaller voltage levels and, as a result, require much smaller ripple levels on the power rails for reliable operation. The challenge is in being able to measure very small mV level signals riding on 1 to 3 V power rails accurately. This video addresses this measurement using the R&S®RTE oscilloscope with its low noise front end and fast update rate which allows quick and accurate measurements of peak to peak ripple voltages. With the spectrum view even more insides in the signal are possible.

Eye diagram measurement with the hardware clock data recovery of the R&S®RTO digital oscilloscope
Serial high-speed data interfaces such as USB 2.0, LVDS, HDMI or PCI-e require a special approach for jitter measurements as they use an embedded clock signal as time reference.

The R&S®RTO digital oscilloscope with option R&S®RTO-K13 performs clock data recovery in hardware and real-time. This enables triggering on the embedded clock as well as fast histogram and eye mask testing on high-speed serial data signals with embedded clock.
