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. • Designed specifically for Agilent Technologies microwave system amplifiers • Bias cable permits remote placement • Compact size for easy system integration The 87422A is a 90 watt, ±15V dc power supply designed to power the Agilent 83020A microwave system power amplifier. One additional ±12V dc output is provided to power a preamp such as the 83006A or 83017A. Included with the power supply are the necessary 2 meter cables to connect to the amplifier. The 87421A may also be used to provide bias voltages for the Agilent 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.

The power supplies include a power cord with protective ground for connection to 90–240 VAC. Mounting holes are provided as shown in the outline drawings. The power supplies may be mounted in any orientation with user supplied hardware. To ensure continued compliance to product safety and EMC specifications, connect the power supplies to an amplifier only with the cable provided. Do not attempt to modify or extend the dc output cable. For help with special applications requiring longer cables contact your Agilent call center listed on the back page. The power supplies have a fuse located next to the IEC appliance inlet. If it is necessary to replace the fuse, disconnect the power supply from both AC power and the amplifier. Using a slotted screwdriver, open the fuse cover and replace the fuse. The power supplies contain no user serviceable parts (with the exception of the fuse). If service is required, please contact your Agilent sales office or nearest Agilent Service Center. The Agilent 87421A power supply provides the dc power needed to bias the 83006A, 83017A, and 83018A. The power supply comes with a 2 meter long cable to allow easy connection between the amplifier and the power supply. Dimensions in millimeters and (inches).
