The PZ4000 stands out with its Power Meter, which displays measured waveforms and power calculations derived from high-speed sampling. As measured voltages and currents are stored in internal memory, they maintain a correlation that enhances reliability and reduces measurement errors. This capability allows simultaneous checks of waveforms and calculated values, eliminating reliance on conventional oscilloscope measurements.
The analyzer excels in high-precision measurements across a diverse frequency range, making it suitable for evaluating power loss in electronic components and advanced lighting systems operating at elevated frequencies. Notably, it enables accurate power measurements at frequencies between several tens of kHz and 100 kHz, a critical feature for modern technology research.
Specialized Measurement Functions:
- Fluorescent Lamp Current Measurement: Utilize the Delta Computation function to assess katode and output current discrepancies in fluorescent lighting systems.
- Power Loss Assessment: Measure real-world power losses under load conditions, moving beyond traditional small signal assessments by LCR meters or impedance analyzers.
- Precision in Low-Frequency Signals: Harness the optional 4M word internal memory for accurate measurement of low-frequency signals (as low as several mHz).
- Dynamic Load Capture: Capture and store fluctuating load data effectively, with capabilities to calculate and display values for segmented memory regions for enhanced analysis.
- Inrush Current Measurement: Simplifies measurement of inrush current and power at switch-on, outperforming conventional methods.
- Graphical Power Analysis: Visual representation of harmonic analysis data up to the 500th order, featuring FFT calculations, displayed through intuitive spectrum graphs.
The PZ4000 is designed to conduct seamless spectrum analysis on inverter carrier components without the complications of probe tolerances, fostering a streamlined approach to performance assessments. The vector display feature allows for instant visual evaluations of phase conditions in three-phase systems, greatly enhancing analytical efficiency.
