Current transducer instructions The high-accuracy fixed core current transducers that are available for the Tektronix PA4000 Power Analyzer are described on the following pages. These transducers are sourced from LEM, a high-quality electronic component supplier. Included with the transducers are Tektronix-designed interface cables that provide easy connections to the PA4000 Power Analyzer.
The transducers that are covered in these instructions all use a 1.3–meter long interface cable that connect to the 1 A and ALO inputs on the rear of the PA4000. However, depending on the transducer series and model, an adapter may be included to complete the connection to the transducer or to an external power supply.

The adapter is included with the CT-1000-S transducer. A suitable power supply is available from Keithley; order model number 2220. The Keithley 2220 power supply is capable of powering two CT-1000-S transducers. Figure 4: CT-1000-S transducer connections PA4000 Power Analyzer...
Power supply, dual output, ±15 V @ 1 A each (order directly from Keithley) Keithley model number 2220 Connections between CT-M series transducers and the PA4000 require a cable adapter. Order Tektronix part number 174-6353-00. The CT-1000-S transducer requires an external power supply; Keithley model number 2220 is a recommended supply.
