GHZ WIDEBAND HIGH SPEED FIXED GAIN HSA-X
In addition to the features of the HSA-X the HSA-Y is equipped with a DC-monitor output useful for photodetector alignment or cw-power control or for the measurement of low frequency background signals. Furthermore, the HSA-Y features two identical signal outputs enabling signal control or triggering without the need for an external signal splitter.
