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*1and 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.
*1To ma ke 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.

Tektronix Oscilloscopes and Probes Supported
TPS2000 Series Oscilloscopes – TPS2012, TPS2014, TPS2024.
Current Probes
A621, A622, TCP202 with 1103 power supply, TCPA300 with TCP312, TCP305,
TCP303, TCPA400 with TCP404XL, P6021, P6022, CT2, CT4 with TCP202 and
1103 power supply.
Passive Voltage Probes
P2220 – 200 MHz, 1X/10X switchable passive probe.
P5120 – 200 MHz passive 20X high-voltage probe.
