Tektronix IsoVu Isolated Voltage Probes | Probe Tegangan Terisolasi

Uncover the fast, floating signals that your non-isolated probes are hiding. IsoVu Probe Technology virtually eliminates common mode interference using optical isolation. This delivers accurate differential measurements on reference voltages slewing ±60kV at 100V/ns or faster. And with our IsoVu Generation 2 design, you get all the benefits of IsoVu technology at 1/5 of the size.

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.

Less Common Mode Noise, More Detail

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 greatly reduces common mode interference. In combination with a 4, 5 or 6 Series MSO, IsoVu provides an efficient, reliable way to resolve high-bandwidth differential signals with fast-slewing references, allowing you to spend less time “designing blind” in a variety of situations: Isolation Addresses Common Sources of Differential Measurement Error

Breaking ground loops

High Differential Voltage at a Range of Bandwidths

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 ±2500V. IsoVu Gen 2 offers a range of bandwidths – 200 MHz, 500 MHz, and 1 GHz – to fit your budget and build your bench with the performance necessary for your specific projects.

Innovative Technology in a Space-Saving Design

IsoVu Generation 2 probes offer the same bandwidth, common mode rejection, and voltage range as our original IsoVu probes, but at 1/5 of the size and without a separate controller box. The lasers and analog electronics are contained in the compact head and oscilloscope connector. Compared to our original IsoVu probes, Generation 2 probes also have:

Better DC gain accuracy
Improved step response
More built-in ranges

High Performance with Convenient Connections

IsoVu probe tips have a range of connections and accessories that offer high performance and accessibility. For example, MMCX connectors are inexpensive, widely available connectors that make for stable, hands-free test points and offer the best bandwidth and common mode rejection. Their solid metal body shields the center conductor and minimizes ground loop area for the lowest interference possible. Other accessories are available to adapt the probe tips to a wide range of connections. Additional 0.100” and 0.200” spaced square-pin tips are available for applications that require greater than ±250V differential voltage. When not using a tip, the sensor head has 1 MΩ and 50 Ω switchable termination at the probe’s SMA connector. This feature effectively adds an isolated channel to any compatible oscilloscope.

Aplikasi

Floating Measurements on Power Supplies | Pengukuran Mengambang pada Catu Daya

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…

Measuring Current Through Shunt Resistors | Pengukuran Arus melalui Resistor Shunt

Measuring the differential voltage across a shunt resistor should be an easy way to get accurate current measurements. But due to the common mode voltages involved, it can be surprisingly challenging. IsoVu, with its high common mode voltage rating and…

Debugging ESD Issues | Debugging Masalah ESD

Going beyond functional testing to troubleshoot the root cause of ESD failures can be frustrating. When using conventional electrical probes, the ESD discharge couples into the probe and propagates down the cable to the oscilloscope, even if the scope is…
