Power Circuit Probe Bandwidth Increased To 4GHz For Embedded Mobile & IoT Devices

Rohde & Schwarz increases the bandwidth of power rail probes to 4 GHz with the new R&S RT-ZPR40 power rail probe. Ideal for embedded mobile and IoT devices, the probe enables scope users to find EMI issues on power rails that they were previously unable to isolate. For measuring power supply quality, it can uncover coupled signals in 2.4 GHz ISM, 3 GHz LTE and higher RF bands, the company says.

“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”, R&S stated in the announcement.

In pursuit of this, R&S offers the new R&S RT-ZPR40 with 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.

The new R&S RT-ZPR40 and R&S RT-ZPR20 probes both offer exceptionally low inherent noise and highest sensitivity with an attenuation factor of 1:1.

With their offset capability, the probes can measure at offset voltages up to 60 V, making them suitable for a wide variety of power rails.

The integrated high-precision DC voltmeter verifies DC tolerance windows while simultaneously measuring the power supply’s DC component with 0.1% accuracy.

The new R&S RT-ZPR40 4 GHz power rail probe and the R&S RT-ZPR20 2 GHz model are now available from Rohde & Schwarz. Standard accessories include a browser adapter and coax pigtail cables.
