  • Large frequency range
  • Wide dynamic range 130 dB typ.
  • Low noise level < -120 dB
  • Low trace noise 1 mdB rms
  • High measurement speed 125 us/point
  • High effective directivity > 45 dB
  • Remote control LAN/GPIB/USB

These VNAs are widely used in microwave device measurement in wireless communication, broadcast, television devices, radar devices, semi-conductors and many more. T5230A and T5280A are all bench top instruments highly suitable for  indoor testing. They are frequently used at production lines, RF laboratories and universities.
