A new lineup of products from test, measurement and monitoring solutions provider Tektronix combines an RF-isolated current probe and a three-channel bidirectional power supply, creating what the company refers to as “breakthrough power instrumentation to fast-track customer innovation in an increasingly electrified world.”
A new lineup of products from Tektronix combines an RF-isolated current probe and a three-channel bidirectional power supply. Source: Tektronix Inc.The lineup includes the new TICP Series IsoVu isolated current probes. According to Tektronix, these are the industry’s first current shunt probes to use RF isolation. By offering complete galvanic isolation between measurement systems and devices under test (DUTs), the probes deliver high-bandwidth, low-noise current measurements in high-voltage applications compared to existing probes on the market or alternative shunt measurement techniques.
Key features of the probes include:
- Complete galvanic RF isolation, eliminating ground loops
- More than 30 times higher common-mode rejection (CMRR) than traditional differential voltage probes: 140 dB CMRR at DC, up to 90 dB at 1 MHz
- Ultra-low noise contribution: In a 1X configuration, the 50 Ω input offers extremely low noise of less than 4.7 nV / √Hz (less than 150 μV at 1 GHz)
- Available in three models with bandwidths of 1 GHz (TICP100), 500 MHz (TICP050) and 250 MHz (TICP025)
- Uses TekVPI probe interface to integrate with Tektronix 4, 5, and 6 series MSO oscilloscopes
Also included in the new lineup is the EA-PSB 20000 Triple series. As the first triple-channel, bidirectional DC power supply, according to Tektronix, the device is capable of delivering high-density, parallel testing for components in complex systems. Each of its 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 auto-ranging, 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 of the power supply include:
- Three independent, fully isolated bidirectional DC channels
- Acts as a DC electronic load for energy recycling, offering up to 96% energy recovery
- Supports up to 30 kW total power, voltages from 0 to 60 V up to 0 to 920 V, and currents from 0 to 40 A up to 0 to 340 A 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
Like the company’s acquisition of EA Elektro-Automatik in January 2024, the new lineup reflects Tektronix’s commitment to advancing power innovation and equipping engineers with the tools they need to drive development in complex electrical settings.
