Audio output is provided for 5s each time the signal reaches its initial maximum, how-
ever only if it is higher than -90 dBm (10% of the total y-axis range) in order to ignore
noise.

Example: Demodulating and Providing Audio Output Continuously
This example demonstrates how to demodulate markers and provide audio output in a
basic spectrum measurement in a remote environment. It assumes that the basic fre-
quency sweep described in chapter 11.15.1, "Programming Example: Performing a
Basic Frequency Sweep", on page 1088 has been performed and thus does not begin
by presetting the instrument.

CALC:MARK1:FUNC:DEM:CONT ON
//Activates continuous demodulation
