Connect the HP8482A power sensor to the power meter.
Zero and calibrate the HP8482A power sensor using the power meter Power
Connect a BNC adapter to the HP8482A power sensor.
Connect a 50Ω SMA cable to the RF output of the HP8648B
generator and then through the necessary adapters to the power sensor. It is
very important that the same cable/generator be used throughout this BW
procedure and that the SMA connectors are torqued at all their mating locations.
