Tektronix TIVP02L - IsoVu 200 MHz Isolated Probe with 10m Fiber Cable

IsoVu probe technology delivers accurate differential measurements up to ±2500 V on reference voltages slewing ±60 kV at 100 V/ns or faster. With the IsoVu Generation 2 design, you get all the benefits of IsoVu technology at 1/5 of the size of first generation probes.

With versatile MMCX connectors and an unmatched combination of bandwidth, dynamic range, and common mode rejection, IsoVu Gen 2 probes are setting new standards for isolated probe technology and enabling wide band gap power designs using SiC and GaN.

Benefits of IsoVu Probes

IsoVu technology uses power-over-fiber and an optical analog signal path for complete galvanic isolation between the measurement system and your DUT. By allowing the probe to float independently at the common mode voltage, isolation provides important advantages.

• 160 dB (100 million to 1) CMRR at DC
• Up to 120 dB (1 million to 1) CMRR at 100 MHz
• Up to 80 dB (10,000 to 1) CMRR at 1 GHz
• ±60 kV Common Mode Voltage range
• Up to ±2500 V differential input Voltage range
• Up to ±2500 V offset range

High Voltage and High Bandwidth

With traditional differential probes you had to choose between high bandwidth or high voltage levels. IsoVu probes, with their shielded coaxial cable and isolation, provide high bandwidth and a differential voltage range of ±2500 V. IsoVu Gen 2 offers bandwidths of 200 MHz, 500 MHz, and 1 GHz to fit your budget and performance needs.

Floating Measurements in Power Converter and MotorDrive Designs

Making high-side measurements in half-bridge power converters is challenging because the source or collector to which the measurements are referenced is slewing rapidly up and down. Wide bandgap devices like SiC and GaN FETs are even harder to measure because they can switch high voltages in a few nanoseconds. Noise from this rapidly changing common mode voltage leaks into the differential measurements and hides details on VGS and VDS. IsoVu probes have unmatched common mode rejection at full bandwidth that lets you see signal details, often for the first time.
