Overview
The R&S®RT-ZISO isolated probing system uses a power-over-fiber architecture to isolate the device under test from the oscilloscope completely, which takes ground loops out of the measurement. The system reaches 1 GHz of bandwidth and still holds more than 90 dB of common mode rejection there, with a ±60 kV common mode range, a ±3000 V differential input range and a CAT III 1000 V safety rating. It connects either through the R&S® oscilloscope probe interface or an SMA connector, and the formable tip cable reaches into crowded board test points and stays put. Bandwidth can be upgraded in the field, which protects the investment. It suits power electronics, wide bandgap devices (GaN/SiC) and any fast-switching high-voltage environment where the measurement still has to be accurate.
Key features
- Fiber-optic isolation: power-over-fiber removes every electrical contact between the DUT and the oscilloscope, which is what gives the system its common mode rejection
- Class-leading CMRR: > 90 dB at 1 GHz, > 115 dB at 100 MHz and > 145 dB at 1 MHz, suppressing high-frequency common mode noise
- Very high common mode and differential ratings: ±60 kV common mode range, ±3000 V differential input and offset range, certified CAT III 1000 V
- Upgradeable bandwidth: start at 100 MHz and upgrade in the field to 200 / 350 / 500 MHz / 1 GHz, protecting the investment
- Formable tip cable: the tip cable bends and holds its shape, so it reaches tight test points and keeps steady contact
- Dual connectivity: the R&S® oscilloscope probe interface (with automatic detection) and a standard SMA connector for third-party instruments
- A choice of tips: MMCX (1.5× / 10×), square pin (25× / 100×) and isolated browser probes (10× / 100×) cover the range of test needs
- Thermal drift compensation: built-in temperature compensation keeps the signal accurate through long measurement runs
- Plug-and-play integration: R&S® oscilloscopes (RTO6, MXO series and others) detect and configure the probe automatically
Typical applications
- High-side gate measurement in power electronics: high-side drive signals in complementary switching circuits (bridges, inverters)
- Wide bandgap (WBG) device test: fast-switching characterisation of GaN and SiC devices
- Measurement in high-voltage, high-noise environments: accurate waveform capture around motor drives, power converters and variable frequency drives
- Power system safety measurement: CAT III 1000 V rated, for safety verification on industrial power systems
- EV charging system test: isolated measurement on chargers, on-board chargers (OBC) and DC-DC converters
- Aerospace and defence power electronics development: design verification and characterisation of high-reliability power modules
