The Agilent 87130A is a 3 1/2 inch, full-width System II attenuator/switch driver capable of driving up to 248 bistatic electromechanical switch or attenuator sections. The Agilent 87130A is controlled over GP-IB via Standard Commands for Programmable Instruments (SCPI) commands. It has been designed for use in both ATE switching systems and computer-controlled bench top applications. The Agilent 87130A has no front panel controls. Manual control is realized through an ITG driver and a computer controller. The Agilent 87130A can drive 31 switches via seven additional Agilent 84940A driver cards.
