The Keysight N9912A-010 is a vector network analyzer time domain option for the N9912A.

Using time domain, data from transmission or reflection measurements in the frequency domain are converted to the time domain. The time-domain response shows the measured parameter value versus time.

Please note, this option requires option N9912A-303 (sold separately).

• Low-pass step
• This stimulus, similar to a traditional time domain reflectometer (TDR) stimulus waveform, is used to measure low-pass devices. The frequency-domain data should extend from DC (extrapolated value) to a higher value.
• Low-pass impulse
• This stimulus is also used to measure low-pass devices.
• Bandpass impulse
• The bandpass impulse stimulates a pulsed RF signal and is used to measure the time-domain response of band-limited devices

Windows

The windowing function can be used to filter the frequency-domain data and thereby reduce overshoot and ringing in the time-domain response.

Gating

The gating function can be used to selectively remove reflection or transmission time-domain responses. In converting back to the frequency domain the effects of the responses outside the gate are removed.
