The Keysight N9912CU/010 is the VNA time domain option for the Keysight N9912C. This option requires the instrument to be configured with a network analyzer (NA) function.

With NA Mode, Time Domain (Opt 010), frequency information is used to calculate and display measurements with time as the horizontal display axis. The response values appear separated in time allowing a different perspective of the test device's performance and limitations.
