NRP-Z21 Three-Path Thermal Power Probe

Product Overview
The NRP-Z21, manufactured by Rohde & Schwarz, is an average power sensor based on thermocouple technology. Its key feature is the integration of three independent measurement paths, enabling highly accurate measurements across an extremely wide power range through intelligent automatic switching or combination of these paths.

Key Features

• Three-Path/Three-Diode Technology
  Contains three independent thermocouple detectors, each optimized for different power levels:
  ? High-power path
  ? Medium-power path
  ? Low-power path
  The instrument automatically selects the optimal path to ensure maximum accuracy across the entire measurement range.

• Wide Dynamic Range
  Frequency range: 50 MHz to 18 GHz
  Power range: -67 dBm to +23 dBm (approximately 200 pW to 200 mW)
  Can directly measure signals from extremely weak to moderate intensity without external attenuators.

• High Precision
  Measurement uncertainty as low as <3.5% at +20°C calibration temperature
  Maintains excellent accuracy across wide temperature variations

• Fast Measurement Speed
  Normal mode: up to 200 readings/second
  Fast mode: up to 10,000 readings/second
  Ideal for high-throughput applications such as production testing

• Connectivity & Compatibility
  USB interface for direct connection to computers or compatible power meters (e.g., R&S NRP series)
  Plug-and-play operation

Main Applications
The NRP-Z21's high precision and wide dynamic range make it suitable for demanding test scenarios:

• RF component testing: Precise measurement of amplifiers, attenuators, and filters for gain, loss, and compression characteristics

• Mobile communication equipment testing: Transmit power measurement for base stations and mobile devices

• R&D and verification: High-precision power measurement and calibration in laboratory environments

• Production testing: High speed and reliability make it ideal for power verification in automated production lines
