Benefits of the Ceyear 3671 2/4 Port VNA Series

  • TDR time domain impedance test, eye diagram analysis.
  • High dynamic range of 135 dB.
  • Suitable for radar, communication field, material science etc.

Ceyear 3671C/D/E Vector Network Analyzers/VNA up to 14/20/26.5 GHz

The Ceyear 3671 VNA (vector network analyzer) series includes three versions 3671C (100 kHz/10 MHz to 14 GHz), 3671D (100 kHz/10 MHz to 20 GHz), and 3671E (100 kHz/10 MHz to 26.5 GHz). The Ceyear 3671 series VNAs have a wide high-resolution touchscreen and offer various display formats such as logarithmic amplitude, linear amplitude, standing wave, phase, group delay, Smith chart, and polar coordinates. The devices also support multiple calibration types including frequency response, single port, response isolation, enhanced response, and full dual port, electronic calibration. Besides all traditional VNA standard measurement functions the Ceyear 3671 series devices offer additional functions through options such as multifunctional and comprehensive parameter test of amplitude frequency characteristics, phase frequency characteristics, and group delay characteristics. They are equipped with standard interfaces USB, LAN, GPIB, VGA, and HDMI.

  • Wide frequency coverage, 100 kHz/10 MHz to 14, 20, or 26.5 GHz (not expandable with extenders).
  • Optional IF bandwidth, max. IF bandwidth up to 30 MHz.
  • Advanced calibration methods, calibration guidance, flexible calibration types, compatible with various calibration kits.
  • Multiple display formats such as logarithmic amplitude, linear amplitude standing wave, phase, Smith chart.
  • 12.1"/30.7 cm, 1280x800 high resolution touch screen.
  • Record/run, one-click operation greatly simplifies measurement setup steps and improves efficiency.
  • Advanced time domain analysis incl. TDR impedance measurement and eye diagram analysis function.
