- The RT-ZHD high voltage differential probes from Rohde & Schwarz are designed for measurements on power electronics with voltages up to 6000 V.
- They offer a measurement bandwidth of up to 200 MHz, a common mode rejection ratio (CMRR) and a 0.5 percent DC measurement accuracy.
- Rohde & Schwarz also presents high voltage differential probes with a 25 MHz bandwidth for general applications.
- These high voltage differential probes enable measurements with the new R&S RTM3000 and RTA4000 oscilloscopes.
R&S RT-ZHD high voltage differential probes
The R&S RT-ZHD high voltage differential probes are designed for measurements on modern power semiconductors. With a bandwidth of up to 200 MHz, they can measure fast switching edges. The common mode rejection across the entire frequency range suppresses fast-switching common mode signals. There are four different models with maximum peak voltages from 750 V to 6000 V.
The integrated offset compensation operates independently of probe attenuation and the oscilloscope’s vertical settings. This makes it possible to measure even small ripple voltages with a DC component. The RT-ZHD probes offer an offset compensation of up to 2000 V and ± 0.5 percent DC measuring accuracy. They also feature an integrated R&S ProbeMeter that measures DC offset with ± 0.1 percent accuracy. The readings are displayed directly on the oscilloscope.
Complete integration of the R&S RT-ZHD probes into the user interface of Rohde & Schwarz oscilloscopes eliminates erroneous readings. The oscilloscopes automatically recognize the configured attenuation factor as well as all other probe settings, so they always display the correct voltages and detect incidents such as overvoltage. Probe functions can also be accessed via the SCPI remote control interface.
The RT-ZHD probes are compatible with both the new R&S RTM3000 and RTA4000 oscilloscopes as well as the Windows-based RTE1000 and RTO2000 oscilloscopes.
R&S RT-ZD002/-ZD003 probes
Two other new additions are the R&S RT-ZD002 and RT-ZD003 differential probes with maximum input voltages up to 700 V and 1400 V, respectively. These 25 MHz probes offer an inherent noise of around 7 mV (RMS) and 14 mV (RMS), respectively.
Their BNC interface makes them suitable for R&S RTC1000, RTB2000 and all standard oscilloscopes.
