Fixed core Hall-effect transducers

Tektronix provides a variety of fixed core and split core current transducers matched to our power analyzers to fit your application and measurement needs. Fixed core transducers provide the highest accuracy available for both AC and DC current measurements, while the split core devices are ideally suited to making measurements in less accessible applications.

PA-LEADSET Replacement lead set for Tektronix power analyzers. This insulated, stackable test lead set is rated for 1000 V, 32 A, CAT II, and is UL61010 compliant.

BB1000 Breakout Box

The BB1000 Breakout Box makes wiring connections between your device-under-test and Tektronix power analyzers easy and safe, by 'breaking out' the current flow for connection to the internal current shunt in the analyzer. It provides a line output socket to power your device under test (up to 10 ARMS) and 4 mm sockets for direct connection to the Tektronix power analyzer terminals. The BB1000 Breakout box is offered in different versions with these receptacle styles:

  • BB1000-UN: 120 V/240 V Universal receptacle
  • BB1000-NA: 120 V North America receptacle
  • BB1000-EU: 240 V Euro receptacle
  • BB1000-UK: 240 V United Kingdom receptacle

Ballast-CT

The Tektronix Ballast-CT simplifies the measurement of output power and tube current in high frequency electronic lighting ballasts. This device is specifically designed for lighting applications, and overcomes problems that are usually found when using conventional or Hall Effect current transformers. When used in conjunction with a Tektronix PA1000 or PA3000 power analyzer, the free-standing Ballast-CT accessory provides a convenient and accurate solution to taking power measurements in lighting ballast circuits.

BALLAST-CT
  • Convenience: No need to feed cables through a CT core
  • High accuracy: Trifilar-wound toroidal design
  • No cable positioning/contact error
  • Wide bandwidth: High frequency design provides 5 kHz to 1 MHz bandwidth
  • Wide current range: 5 mA to 1 A is compatible with many modern ballasts
