Agilent (Hewlett-Packard) 8720B Microwave Network Analyzer

The 8720B Microwave Network Analyzer can characterize microwave components and networks from 130 MHz up to 20 GHz. This vector network analyzer includes a fast-sweeping synthesized source, switching s-parameter test set, and large full color display in a single integrated package. The unit has a dynamic range of 85 dB. The built-in test set measures all four s-parameters (both forward and reverse) with a single connection. A step attenuator controls incident power level from -10 to -65 dBm in 5 dB steps, and two internal tees provide bias to active devices through the test ports.
