Installation
WARNING. To reduce risk of shock or fire, refer to the PA4000 Power Analyzer
User Manual, Tektronix part number 077-0815-xx, before using the transducers
and power analyzer.
The PA4000 Power Analyzer User Manual contains a complete list of
specifications and operating information for the 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.
If your application requires a cable length greater than 1.3 meters, a standard
DB-sub 9 extender cable may be used.
The interface cable that is supplied with the transducers includes a 3-pin power
connector that connects to the rear panel of the power analyzer. All transducers
except the CT-1000-S model are powered by the PA4000 internal supply.

Current transducer instructions
CT-M series transducers All CT-M series transducers include a DB-sub 9-pin to 3-pin adapter, which mates
the interface cable to the 3-pin connector on the transducers.

Current transducer instructions
CT-S series transducers All CT-S series transducers use the standard interface cable to make the connection
to the PA4000 power analyzer. The CT-1000-S model is powered by an external
power supply, and is described on the following page.
Figure 3: CT-S series transducer connections
4PA4000 Power Analyzer

Current transducer instructions
CT-1000-S transducer If you are using the CT-1000-S transducer, you must connect the transducer to
an external power supply. The power for the transducer runs from the external
supply through a cable adapter that connects to the standard interface cable. 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.
