Agilent/ HP 355C Step Attenuator dc to 1000 MHz

Accuracy is guaranteed using a step attenuator. Cam-actuated microswitches are utilized to install and remove attenuator sections, keeping lead lengths small. With this design, phase shift is minimal along inductances and capacitances. This device is compact, but its components are strategically placed and protected. This way, stray pick-up or signal leakage will not be a problem.
