on page 1203 has been performed and thus does not begin by presetting the instru-

In this example, the peak search is restricted to the frequency range of 50 MHz to 150
MHz. The top 5 power levels with a peak excursion of 10dB and a minimum of -100
dBm are to be determined and displayed with their marker numbers. The results are
sorted by frequency values. The resulting peak list is then exported to a file.

Example: Measuring Noise Density
This example demonstrates how to measure noise density using noise markers in a
basic spectrum measurement in a remote environment. It assumes that the basic fre-
quency sweep described in
"Basic Frequency Sweep Measurement for Marker Func-
tion Examples" on page 1203 has been performed and thus does not begin by preset-
ting the instrument.

//Queries the measured noise level (per Hz bandwidth)
Example: Measuring Phase Noise
This example demonstrates how to measure phase noise using markers in a basic
spectrum measurement in a remote environment. It assumes that the basic frequency
