Rohde & Schwarz broadens its oscilloscope portfolio for power rail probing by introducing the R&S RT-ZPR40 power rail probe with 4 GHz bandwidth. Targeting embedded mobile and IoT devices, it can uncover coupled signals in 2.4 GHz ISM, 3 GHz LTE and higher RF bands.
Power supply quality is a key factor in the functionality and performance of sensitive electronic circuits. Embedded designs with incorporated RF modules face the additional risk that RF signals are coupled onto the power rails of sensitive electronic components such as microprocessors, fast memory components and sensitive analog circuits, impairing the functionality of the device.
The new R&S RT-ZPR40 offers a 4 GHz bandwidth with a direct SMA connection or a 50 Ω pigtail coax connection to uncover such problems. The probe is ideal for use with the 4 GHz and 6 GHz R&S RTO2000 oscilloscopes. This combination allows the user to take advantage of the oscilloscope’s powerful FFT functionality and serial protocol decoding. Joerg Fries, Vice President Market Segments for T&M at Rohde & Schwarz, states: “The 4 GHz probe enables scope users to find EMI issues on power rails that they were previously unable to isolate.” If 4 GHz bandwidth is not necessary, the R&S RT-ZPR20 probe with 2 GHz bandwidth is an attractive alternative.
