The Agilent HP 8720B Network Analyzer can characterize microwave components and networks from 130MHz up to 20GHz. 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. Option 010 provides the capability of transforming measured data from the frequency domain to the time domain.

Digital signal processing and microprocessor controls combine to provide easy operation and measurement improvement. Measurement functions are selected with front panel keys and softkey menus. Two independent display channels and a large screen color CRT display the measurement results of one or both channels, in logarithmic, linear, or Smith chart display formats.

Trace math, data averaging, trace smoothing, electrical delay, and accuracy enhancement provide performance improvement and flexibility. Accuracy enhancement reduces the effects of repeatable measurement variations in the test system. Displayed measurement results can be printed or plotted directly to a compatible peripheral without the use of an external computer. Instrument states can be saved in internal memory for at least three days without line power to the instrument. In addition, each analyzer can control a compatible disk drive for external storage capability. Built-in service diagnostics are available to simplify troubleshooting procedures.
