Isolated current probes utilise RF isolation

The new lineup includes an industry-leading RF isolated current probe and three-channel bidirectional power supply

Tektronix, Inc, announces a new lineup of breakthrough power devices set to accelerate innovation in industries demanding greater power capacity and efficiency. The new TICP Series IsoVu isolated current probes are the world’s first to utilise RF isolation, delivering exceptional precision and safety when measuring fast-changing current across both low- and high-voltage systems. The EA-PSB 20000 Triple series is a three-channel, bidirectional power supply and electronic load with energy recovery that delivers higher test coverage, density, and capacity across multiple channels within a single device.

The TICP IsoVu probes are available to order now and will begin shipping this month, November 2024. The EA-PSB 20000 Triple output power supply is available for pre-order today, with shipping beginning in January 2025. 

TICP IsoVu probes are the industry’s first current shunt probes to use RF isolation, providing complete galvanic isolation between measurement systems and devices under test, delivering high-bandwidth, low-noise current measurements in high-voltage applications compared to existing probes on the market or alternative shunt measurement techniques. Available in bandwidths up to 1GHz, these probes enable engineers to capture accurate measurements of fast-changing currents on their oscilloscopes across a wide voltage range in nanoseconds – from microamps to kiloamps. 

Key features: 

Complete galvanic RF isolation, eliminates ground loops

More than 30X higher common-mode rejection (CMRR) than traditional differential voltage probes: 140dB CMRR at DC, up to 90dB at 1MHz

Ultra-low noise contribution – in a 1X configuration, the 50Ω input offers extremely low noise of <4.7nV / √Hz (<150μV at 1GHz)

Available in three models with bandwidths of 1GHz (TICP100), 500 MHz (TICP050), and 250 MHz (TICP025)

Uses TekVPI probe interface to integrate with Tektronix 4, 5, and 6 series MSO oscilloscopes

The EA-PSB 20000 Triple series is the first triple-channel, bidirectional DC power supply, capable of delivering high-density, parallel testing for components in complex systems. Each of the three independent channels can supply up to 10 kW of power, supporting a range of voltages up to 920 V and currents up to 340 A. The series allows customers to consolidate multiple testing setups into one, reducing cost, equipment needs, and test time. It also features autoranging, which automatically adjusts the voltage or current to deliver full power across a wide operation range, allowing a single unit to handle various voltage and current combinations. 

Key features:

Three independent, fully isolated bidirectional DC channels

Acts as a DC electronic load for energy recycling, up to 96% energy recovery 

Supports up to 30 kW total power, voltages from 0 – 60V up to 0 – 920V, and currents from 0- 40A up to 0-340A per channel 

Advanced parallel testing with galvanically isolated Share-Bus

High-speed CAN-FD communication interface

Reduces required rack space by 50% compared to single output devices.
