Transformation To Time Domain; Measurement Flow - Agilent Technologies ENA Series User Manual

Analysis in Time Domain (Option 010)

Transformation to time domain

Transformation to time domain
The transformation function lets you transform a response in the frequency domain to the
corresponding response in the time domain.

Measurement flow

Table 9-1 shows the measurement flow of this transformation.

Description
Selects the transformation type from the following.
• Band pass mode
You can set the sweep range arbitrarily. This is suitable for devices through
which signals within a certain frequency range pass such as filters.
• Low pass mode
Simulates the TDR measurement. This mode is suitable for devices through
which dc current or signals of many frequencies pass, such as cables.
The low pass mode provides two types of modes: low pass step and low
pass impulse.
Sets the window to reduce the ringing phenomenon, in which a waveform's
waves are caused due to the fact that the frequency domain is finite.
Calculates the following values to obtain the necessary resolution and
measurement range in the time domain.
• Sweep range
• Number of points
• Window width
Sets the sweep range and the number of points to the values calculated above.
Sets the range displayed on the graph.
Enables the transformation function.
