Rohde & Schwarz once again sets new benchmarks – with the R&S®ZNB vector network analyzers. The new family of network analyzers features high measurement speed, outstanding precision and exceptional ease of operation.

The R&S®ZNB vector network analyzers feature a wide dynamic range of up to 140 dB (at 10 Hz IF bandwidth), low trace noise of less than 0.004 dB RMS (at 10 kHz IF bandwidth) and high output power of up to +13 dBm, which can be adjusted electronically in a range of more than 95 dB.

With frequency ranges of 9 kHz to 4.5 GHz and 9 kHz to 8.5 GHz, the new network analyzers are primarily targeted at applications in the mobile radio and electronic goods industries. The R&S®ZNB is the right choice when it comes to developing, producing and servicing RF components such as amplifiers, mixers, filters and cables.

The new analyzers combine high measurement accuracy with exceptional speed – better than 10 μs per point. They feature excellent temperature and long-term stability, which ensures reliable measurements over several days without having to recalibrate the units.

These short-depth, compact two-port and four-port analyzers leave plenty of space on the workbench for the measurement application. They feature low operating noise thanks to low power consumption and a sophisticated cooling concept. The low power consumption also reduces operating costs and protects the environment.

  • Wide dynamic range of up to 140 dB, from 9 kHz for fast measurements on high-blocking DUTs 
  • Short sweep times of 4 ms for 401 points
  • Excellent raw data for high basic accuracy
  • High temperature stability of typically 0.01 dB/°C
  • Fast embedding/de-embedding for impedance matching using virtual networks
  • Mixed-mode S-parameters for balanced DUT characterization
  • Extensive analysis functions for convenient trace analysis
  • Amplifier measurements with wide power sweep range and receiver step attenuators
  • Time-domain analysis for distance-to-fault (DTF) measurements and filter adjustment
  • Wide range of IF bandwidths from 1 Hz to 10 MHz
  • Manual and automatic calibration
  • Large, high-resolution 12.1" screen
  • Flat and clear menu structures for efficient operation
  • Touchscreen user interface
  • Two or four test ports
