Rohde&Schwarz Rohde & Schwarz R&B® ZISO series optically isolated probe 100M/200M/350M//500M/1G high-frequency

The R&S®RT-ZISO isolated probing system is capable of tackling measurement challenges in high-voltage and fast-switching environments.

The fiber-optic powered architecture electrically isolates the device under test (DUT) while maintaining the highest possible common-mode rejection ratio (CMRR) even at bandwidths up to 1 GHz.

The entire system compensates for thermal drift and gain errors, ensuring first-class signal fidelity.

Key Features

Handling the Challenge of Fast Common-Mode Signals

The R&S°RT-ZISO isolated probing system can suppress interference from fast common-mode signals through optical isolation, achieving a CMRR greater than 90 dB at 1 GHz bandwidth.

This is beneficial for high-voltage side gate measurements in complementary switch circuits, especially for wide-bandgap devices.

• 1 GHz: > 90 dB

• 500 MHz: > 100 dB

• 100 MHz: > 115 dB

• 1 MHz: > 145 dB

The Probe Front End is Crucial

The R&S'RT-ZISO offers multiple probe front ends, among which the MMCX probe front end is the most important for ensuring excellent CMRR performance.

The probing system also supports various interfaces with different attenuation ratios, including jack and wide-jack types. The probe front-end cables are long and easy to shape,

allowing easy access to probing points while applying very low mechanical stress to the points being measured.

Easily Set Up with R&S Oscilloscopes

Connecting the R&S'RT-ZISO to an oscilloscope via the R&S probe interface provides a smooth user experience. The oscilloscope can detect the probe front end and set the corresponding information.

Offset and range control can be easily configured using the oscilloscope. Users can also conveniently utilize all features and functions of the R&S oscilloscope during measurements,

such as excellent waveform capture rates and fast-response FFT functionality.

Investment Protection

The R&S'RT-ZISO isolated probe system can be connected to any oscilloscope with BNC or SMA interfaces. Users can select instruments according to performance requirements.

The R&SRT-ZISO bandwidth can be upgraded based on future needs.
