R&S Meters Ban Img TelonicUK

The R&S®NPA family comprises compact, all-in-one testers for DC load, AC load, and standby current characterisation. These instruments eliminate the need for external PC software by providing a high-resolution numerical and graphical display directly on the unit. With a basic accuracy of 0.05% and a wide power measurement range from 50 µW up to 12 kW, the series is built for both R&D labs and production test systems.

Key Series Features

  • High-Resolution Acquisition: 16-bit resolution for current and voltage with a 500 ksample/s sampling frequency.
  • Broad Bandwidth: Supports signal acquisition from DC to 100 kHz.
  • Flexible Display: Simultaneously displays up to 10 user-configurable parameters with a 10 Hz refresh rate.
  • Seamless Integration: Standard Ethernet (LAN) and USB interfaces with SCPI-based remote control; “-G” models include an IEEE-488 (GPIB) interface.
