Vector Network Analyzer

KC901V Handheld 
Vector Network Analyzer is a “RF multimeter”. It offers the capabilities of single port vector network analysis and dual port scalar network analysis, also with spectrum, field strength and signal generator functions. It is a powerful and useful handheld instrument for RF engineer both in lab and on the field.. 

Handheld Vector Network Analyzer

  • Test frequencies up to 6.8GHz with 1Hz resolution and stability better than 1ppm.
  • Providing vector measurement on S11 with 0.01 phase resolution and 0.01db amplitude resolution.
  • With vector measurement capability of S11, it shows the smith chart, RL(Return loss), characters of phase position, and frequency.
  • In S21 scalar measurement, it has the function of single frequency S21 within range of 100dB.*
  • With its non-volatile calibration data built-in, on site calibration is not necessary if performing a qualitative measurement. While performing rigorous test, you may use the SOL to enhance the calibration.
  • A handy field strengthen meter with a high dynamic range.
  • Built in DDS, audio signal source function.
  • Data can be saved in the Memory Card or be transferred into PC via USB.
  • 3.5 inch color-display -Excellent response speed with accurate key feeling, less than 3s ready to use.
  • Functions are stable and reliable with the excellent hardware/software design.
