Can RT-ZD02 / ZD08 Probes be used at RTC/RTB/RTH?

Description

Is is possible to use the differential probes RT-ZD02 or RT-ZD08 on oscilloscopes with high impedance? The impedance of the RT-ZD02/ZD08 is 50 Ohms.

Resolution

This is possible. But it is necessary to insert a feedthrough termination adapter. Then the probe is terminated with 50 Ohms and the high impedance channel of the oszilloscope is in parallel, which does not have significant influence. Any measurements are shown correctly. At the oscilloscope the attenuation of 10:1 has to be set.

We recommend to use the feedthrough adapter " R&S RAD, 0289.8966.00" which can be used up to 1 GHz:
