You can display up to four markers. The marker is displayed MARKER SELECT MARKER MARKER n from. When you display a marker,
the active marker is set to the displayed marker.
Time domain operation
The N anoV N A can simulate time domain measurements by processing the frequency domain data.
DISPLAY TRANSOFRM TRANSFORM ON Select to convert the measurement data to the time domain . TRANSFORM ON If is enabled, the
measurement data is immediately transformed and displayed in the time domain.
The time domain and frequency domain have the following relationship.
Time resolution increases as the maximum frequency increases
The closer the measurement frequencies are (that is, the lower the maximum frequency is), the longer the maximum time
length is.
Therefore, there is a trade-o between maximum time length and time resolution.
When the time length is called distance, the following can be said.
