Making Time Domain Measurements
Resolution
Range Resolution
Time domain range resolution is defined as the ability to locate a single response in time. If only one
response is present, range resolution is a measure of how closely you can pinpoint the peak of that
response. The range resolution is equal to the digital resolution of the display, which is the time domain
span divided by the number of points on the display. To get the maximum range resolution, center the
response on the display and reduce the time domain span. The range resolution is always much finer than
the response resolution (see
Figure 3-25).
