  • Each 4280 series Attenuator/Phase Shifter is factory calibrated with a table containing the optimal attenuation and phase settings across the operational frequency band. This allows the end user to specify a frequency, attenuation, and phase, and receive an extremely accurate result.
  • Latching control scheme allows for both phase and attenuation to be controlled via parallel TTL
