Tektronix 5 PWR

Product Highlights

Get more visibility into your power systems with Advanced Power Measurement and Analysis on the 4/5/6 Series MSO. The combination of the oscilloscope, analysis software, and a wide range of available voltage and current probes, enables you to perform automated, accurate power system measurements even if you are not a power conversion guru. The 12-bit analog-to-digital converters in these oscilloscopes deliver high-precision measurement data, and the pinch/swipe/zoom touch interface makes it easy to manage measurements. A rich set of graphical power analysis tools, high channel-counts, and large HD displays deliver a comprehensive view of your power system. The instruments support a wide range of voltage and current probes, including state-of-the-art IsoVu optically isolated voltage probes. The unmatched common mode rejection of IsoVu probes and the automation of Advanced Power Measurement and Analysis make an unbeatable combination for optimizing the latest GaN and SiC designs.

Key measurements

• Input measurements
  • Power measures true power, apparent power, power factor, and phase angle
  • Total Harmonic Distortion and Crest Factor measurements
  • Harmonics measurements, bar charts, and tables
  • Amplitude provides easy per-cycle measurements of voltage or current, including minimum, maximum, amplitude, and peak-to-peak
  • Input Capacitance measures the capacitance value using voltage and current signals
  • Inrush Current measures the peak current
• Switching Device measurements
  • Switching Loss measures turn-on, turn-off, and conduction loss in switching devices
  • Safe Operating Area (SOA) provides customizable safe operating area mask testing
  • Timing Analysis enables easy analysis of pulse-width-modulated switching signals with cycle-by-cycle plots or histograms of pulse width, duty cycle, frequency, or period
  • RDS(on) measures the dynamic resistance of the switching device when it is in the On state
• Magnetic Analysis measurements (available only in 5/6-PWR)
  • Inductance measures inductance of the core
  • Magnetic Property measures and plots the inductor B – H curve.
  • Magnetic Loss measures and calculates total magnetic loss
• Output measurements
  • Line Ripple measures the amount of AC signal related to the input line frequency.
  • Switching Ripple measures the amount of AC signal related to the switching frequency.
  • Efficiency measures the power circuit efficiency by dividing the measured output power by the measured input power
  • Turn On Time measures the time delay between the input voltage to the device under test going ‘high’ to the output voltage reaching its steady state.
  • Turn Off Time measures the time delay between the input voltage to the device under test going to zero state, to the output voltage reaching its zero state.
• Frequency response measurements(available only in 5/6-PWR)
  • Control Loop Response (Bode) plots the frequency and phase response of a closed loop circuit, and automatically calculates the gain and the phase margins.
  • Power Supply Rejection Ratio (PSRR) analyzes the ripple rejection capability of a DC-DC converter.
  • Impedance Analysis enables 2-port impedance measurement of Power Distribution Networks(PDN) using the oscilloscope.
