Rohde & Schwarz NPA501 Power Analyzer

Overview

The Rohde & Schwarz NPA501 is an advanced power analyzer designed for detailed power quality analysis and production testing. Building on the capabilities of the NPA101 meter, it adds sophisticated analytical features including harmonic analysis, trend charting, and pass/fail monitoring. The brilliant QVGA color display (320 × 240 pixels) simultaneously shows up to 10 user-configurable measurement results at 10 measurements per second. With 0.05% basic accuracy and DC to 100 kHz bandwidth, the NPA501 is ideal for manufacturers requiring comprehensive power compliance validation.
