Optically Isolated Probing System For Oscilloscopes

The Next Ground Breaking Probe Solution

NEXT GENERATION GROUND BREAKING SOLUTION
With optical isolation

The R&S^®RT-ZISO isolated probing system can tackle the challenge of measuring in high voltage and fast switching environments. The power-over-fiber-optic architecture galvanically isolates the device under test (DUT) for the highest possible common mode rejection ratio (CMRR) at up to 1 GHz. The complete systems compensate thermal drifts and gain errors for the highest possible and uncompromising signal fidelity.

Features & Benefits

For Fast Common Mode Probing Challenges

RT-ZISO isolated probing system suppresses interference from fast common mode signals with optical isolation for a CMRR of > 90 dB at 1 GHz. This helps with high-side gate measurements on complementary switching circuits especially wide bandgap devices.

1 GHz > 90 dB
500 MHz > 100 dB
100 MHz > 115 dB
1 MHz > 145 dB

Isolation limits CM noise loop formation in the system.

Probe Tips Matter

RT-ZISO comes in a variety of probe tips and the MMCX probe tip is the most important one for CMRR performance. Different connector types such as square pins and wide square pins are also supported with different attenuation ratios. The probe tip cables are long and formable for easy access to probe points with minimal mechanical stress.

Hassle-Free Setup with Rohde & Schwarz Oscilloscopes

Using the R&S^®RT-ZISO with the Rohde & Schwarz probe interface on our oscilloscopes creates a seamless experience. The instrument detects and sets up the probe tip information. Offset and range control can be easily configured on the instrument. Users can also easily use all Rohde & Schwarz oscilloscope functions and features such as fast acquisition and responsive FFT in their measurements.
