Time Domain (Option 010)

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.

Time stimulus modes

– 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.
