About Windowing

Windowing addresses the problem of spectral leakage when converting signals from the time domain into the frequency domain. Windowing is the process of multiplying the time record by a weighting function, or a window, to force a signal to be periodic in the time record. The window weights the data in the time domain to improve accuracy in the frequency domain.

To learn more about Windowing concepts, see Windowing in the VSA Concepts online help.

When time gating is enabled in Vector or Analog Demod mode, there are two time records: a main time record and a gate time record. You can select the same window or different windows for both of these time records. To select a window for the main time record, click MeasSetup > ResBW. To select a window for the gate time record, click MeasSetup > Time.
