The Keysight 87422 is a universal input, dc switching power supply designed to provide the bias voltages needed to operate Keysight microwave system amplifiers. These compact power supplies are ideal for integration into a sstem or for use on a benchtop. The two-meter dc bias cable permits the amplifier to be remotely located, allowing it to be placed out of the way or where space is not critical. The Keysight 87422A is a 90 watt, plus or minus 15V dc power supply designed to power the Keysight 83020A microwave system power amplifier. One additional plus or minus12V dc output is provided to power a preamp such as the Keysight 83006A or 83017A. Included with the power supply are the necessary two-meter cables to connect to the amplifier.
