Measuring a Device in the Time Domain (Option 010 )The HP 8753D Option 010 allows you to measure the time domain response of a device. Time domain analysis is useful for isolating a device problem in time or in distance. Time and distance are related by the velocity factor of your device under test. The analyzer measures the frequency response of your device and uses an inverse Fourier transform to convert the data to the time domain.
Time domain analysis allows you to mathematically remove individual parts of the time domain response to see the undesirable responses...(read more in the Agilent 8753D users manual starting on page 2-68 )
