  • Frequency range of 200 – 6000MHz*
  • 50 ohms nominal impedance
  • Easy control from 0 – 63dB in 1 dB steps
  • 20dBm operating RF input power
  • Control through switches for set attenuation, reset attenuation and program attenuation
  • Display unit that displays the current set attenuation value
  • Attenuation value is programmable through serial port or through Ethernet port


Digitally controlled variable attenuator perfectly suitable for test automation and for control of attenuator through remote access. Synchronized multiport control is ideal for testing multi-antenna MIMO systems.
