Description
On a motor dyno or a large inverter rig, the scope often sits at a desk outside the test area. The Tektronix TIVP05L IsoVu probe fits that kind of setup. It is an isolated voltage probe, an optically isolated differential design, and it pairs 500 MHz bandwidth with 10 m of fiber. The interface connects to a TekVPI oscilloscope.
TIVP05L versus TIVP05
Both models list 500 MHz. The difference is reach: the TIVP05L has 10 m of fiber, while the TIVP05 has 2 m. So choose the L version when distance between the sensor head and the scope matters more than a compact bench.
Applications on large rigs
Traction inverter teams can probe phase legs while a motor runs on the dyno. Similarly, grid-tie and solar inverter labs may place the scope away from bulky cabinets. Power module makers also run switching tests on fixtures inside guarded areas. Throughout, the Tektronix TIVP05L IsoVu probe lets the head stay at the node while the display stays with the engineer.
Tips, ranges and derating
The tip decides your differential window. Supported tips start at ±5 V, and a high-attenuation configuration reaches ±2500 V. For the TIVP family, the manufacturer lists common-mode capability up to ±60 kV under defined conditions. Still, that limit drops with frequency, and safety derating applies too. TIVPMX10X serves as the standard tip reference, but confirm the kit contents in the quote.
Before the first Tektronix TIVP05L IsoVu probe test
Check that your TekVPI scope and its firmware support the probe. Then plan the fiber route from the rig to the scope bench. Also confirm offset and input limits for the chosen tip in the current manual.
Working with Lost in HCM
Lost in HCM offers the TIVP05L for rent or sale and arranges service on request. A rental suits a dyno campaign or a type-test window. Meanwhile, a plant with a permanent inverter test cell may prefer to buy. To ask Lost in HCM for a quote, include the scope model, signal speed, both voltage levels and the cable distance. You can also view more oscilloscope probes, check the Tektronix website, or contact SMK Vietnam. Follow the manufacturer’s manual and ratings in every Tektronix TIVP05L IsoVu probe setup.
TIVP05L questions and answers
Why would I need 10 m of fiber?
It lets the scope stay outside a cage, chamber or test cell while the sensor head stays on the circuit.
Does the long fiber cut bandwidth?
The source lists 500 MHz for both the TIVP05L and the TIVP05.
What should my quote request include?
Your scope model, signal bandwidth, differential and common-mode voltage, connection layout and needed accessories.
