Manual 87421A Datasheet
The Keysight 87421A power supply is a universal input, dc switching power supplies designed to provide the bias voltages needed to operate Keysight microwave system amplifiers. This compact power supply is ideal for integration into a system or for use on a benchtop. The 2 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 87421A is a 25 watt, ±12V dc power supply designed to power the Agilent 83006A, 83017A, 83018A, and 87415A microwave system amplifiers. A 2 meter cable is included for direct connection to the amplifier.It may also be used to provide bias voltages for the 83440C high speed lightwave converter. Using the 83440-60009 lightwave converter power supply adapter, the 87421A becomes a compact, convenient power supply for use with the lightwave converter.
