Set sweep time to 1 second.

Description Sweep time, sensitivity, and video bandwidth are coupled to yield the maximum, signal-amplitude accuracy. Selecting a sweep time with ST, or

executing ST MAN breaks the coupling. Execute ST AUTO to reestablish coupling. Faster sweep times or measurements are available by changing spectrum analyzer settings as follows:

￿Reduce trace length (TRDEF). The spectrum analyzer requires 10 ms to store measurement results in an 800-point trace. Reducing trace length reduces storage time proportionately.
