Description
QuinStar QPA-AOI599 precision Motorized Programmable Attenuation control can be either manual or remote. The remote control uses a standard IEEE-488 interface. This attenuator’s small package incorporates both the electronic controller and microwave attenuator components. The unit operates with a single 24 volt DC source or with an optional AC adapter. Attenuation range is 0 – 60 dB in 0.1 dB steps with 0.05 dB steps over 0 – 20 dB. A digital readout on the front panel displays the current attenuation setting. This precision Motorized Programmable Attenuator is both highly accurate and highly reliable. Features: Compact size, High accuracy and reliability Digital readout, IEEE-488 interface Manual/motorized operation Applications: Designed by QuinStar Engineers for use in automated test equipment and in applications requiring remote power control.
