KEYSIGHT's N9937AU-220 option 220 allows users to easily make accurate scalar stimulus / response measurements on active and passive components, cables, connectors, and antennas. The full-band tracking generator source can also be decoupled to act as a stand-alone source that can be used to stimulate an active or passive component, optionally using the spectrum analyzer for measurement.

*This is the field-upgrade version. For factory-installed options, please see a sales representative for a customized unit.
