Power Measurement and Analysis Software

As an industrial power designer or technician, you must perform a range of power-specific measurements to develop, test, and race products to market. The TPS2000 Series oscilloscopes, when equipped with TPS2PWR1 power measurement and analysis software, allows you to optimize your productivity by reducing your development and test time with a broad range of power-specific measurements, such as switching loss (including turn-on, turn-off, and conduction losses), harmonic distortion measurements to the 50th harmonic, and dv/dt and di/dt cursor measurements. Use a single instrument to make an array of measurements – from measuring high voltages*1 and high currents to debugging control circuits.

To improve the efficiency of industrial power designs, you must analyze power dissipation and characterize transitions at higher switching frequencies. Using TPS2PWR1’s unique switching-loss feature, you can measure switching-device power dissipation with the touch of a button. Coupled with the TPS2000 Series oscilloscopes’ unique Digital Real-Time (DRT) sampling technology, the TPS2PWR1 software package enables you to efficiently and accurately characterize industrial power systems by measuring power loss at the switching device.

Reduce your development and testing time by using TPS2PWR1’s harmonic testing capability to the 50th harmonic to test power supply designs to these standards from your bench, the power lab, or on-site.

In addition, TPS2PWR1 software enables you to set units and scale factor for Tektronix current and voltage probes to read the result in the right unit.

*1 To make floating measurements greater than 30 VRMS, use optional P5120 or P5122 passive, high-voltage probes, similarly rated passive, high-voltage probes, or appropriately rated high-voltage, differential probes.


Power Measurements - True real power in watts, reactive power in VAR, power factor, crest factor, RMS measurements, frequency measurements.
