The Tektronix PA4000 2-Ch Multi-phase Power Analyzer delivers highly accurate, multi-channel power, energy, and efficiency measurements. Precisely-matched inputs, unique Spiral Shunt technology, and advanced signal processing deliver high accuracy even with highly modulated waveforms and crest factors as high as 10. The versatile Tektronix PA 4000 offers comprehensive power measurements. Dual current shunts provide optimal resolution from microwatts to kilowatts. Harmonics analysis up to the 100th harmonic, and motor analysis with torque and speed inputs are included in the standard instrument. Every Tektronix PA4000 2CH comes with multiple PC interfaces, PC software, and USB flash drive support to help you collect and analyze data.

Flexible Voltage and Current Input Choices to Fit Your Application

The Tektronix PA4000 2-Ch Multi-phase Power Analyzer is the only instrument of its kind to feature both high- and low-range internal current shunts in each input module. The Tektronix PA 4000's 30-Amp shunt is perfect for many applications and can accept up to 200 A peak; but for measuring low-current devices the 1A shunt provides increased resolution and accuracy for measurements down into the microamp range. For measuring currents over 30 Amps, a selection of matching external current transducers are available in several styles, including high-accuracy transducers up to 1000 A. The Tektronix PA4000's voltage inputs can accept up to 1000 Vrms, 2000 Vpeak, continuous.

Unique Spiral Shunt Technology

The Tektronix PA4000 2-Ch Multi-phase Power Analyzer employs an innovative Spiral Shunt design that ensures stable, linear response over a wide range of input current levels, ambient temperatures, crest factors, and other variables. The Tektronix PA4000 2CH's new design is superior to other shunt technologies and contributes to the instrument's reliable accuracy and repeatability over a wide range of signal conditions common in today's power conversion technologies. The spiral construction not only minimizes stray inductance (for optimum high frequency performance) but also provides for high overload capability and improved thermal stability.

Application-Specific Test Modes

Some applications require special instrument settings to ensure proper measurements. The Tektronix PA4000 2CH simplifies setup for these applications by automatically choosing instrument settings and parameters that are optimized for each type of measurement application, resulting in more reliable measurement results with less opportunity for user setup error.

PWM Motor Drive Mode

PWM motor mode is designed to overcome the difficulties associated with making measurements on the complex waveforms commonly found on themotor drives. High frequency sampling is combined with digital filtering toreject the carrier frequency and extract the motor frequency while still usingprefiltered data for power parameters.

Standby Power Mode

Driven by consumer demand and energy efficiency regulations (such as ENERGY STAR), there is an ever-increasing need to measure power consumption of products while they are in standby mode. One of the most widely used standards for measurement is IEC 62301. Part of this standard requires the measurement of power over a prolonged period of time without missing any short duration power events. The Tektronix PA4000 2CH standby power modeprovides continuous sampling of voltage and current to produce an accurate Watts measurement over the user specified period.

Ballast Mode

Ballast mode synchronizes measurements for highly modulated electronic ballast waveforms. In modern electronic lighting ballasts, it is often difficult to make accurate measurements because the output signals are high frequency waveforms that are heavily modulated by the power frequency. Ballast mode provides a way of locking the measurement period to the power frequency.

Integrator Mode

Integrator mode is used to provide measurements for determining energy consumption (Watt-hours, Ampere-hours, etc.). In addition, for certain parameters, average values are also available.

Standard Harmonics analysis

The Tektronix PA4000 2CH features harmonics analysis to the 100th harmonic as a standard feature. Harmonics, THD, and related measurements can all be analyzed simultaneously with other power parameters. Accurate measurement of harmonic amplitude, phase, and harmonic power are included, which are critical to the analysis of losses in rotating machinery.

Standard Communication Ports

The Tektronix PA4000 2CH comes standard with USB, Ethernet, and RS-232 communication ports, plus a front-mounted USB port for data export to a flash drive. GPIB is available as a factory-installed option.
