The Z5623AK08 distribution amplifier enables two Keysight PSG signal generators to operate in a phase locked and coherent mode at a common frequency. It operates in two frequency bands: 250 MHz to 3.2 GHz, and > 3.2 GHz. The upper frequency limit is determined by the frequency range option selected on the PSG (20, 32, 40, 50 or 67 GHz for the E8257D and 20, 32 or 44 GHz for the E8267D).
The distribution amplifier takes an oscillator signal from one signal source, amplifies it and distributes it to multiple other signal sources. The distribution amplifier has two modes of operation: Distribution Mode and Calibration Mode. The mode of operation is manually selected with a switch on the front panel.
In Distribution Mode, there is 1 RF input, 2 RF outputs. In Calibration Mode, there are 2 RF inputs and 2 RF outputs. Each RF input connects directly to it's own corresponding RF output.
