Peak Searching and Markers
The peak auto search feature of the analyzer allows you to measure multiple
peaks simultaneously. Not only does this save time, it also provides a clear
printout of frequency and amplitude data.
If you do not have a signal generator or this signal generator only generates one
peak, you can connect an antenna to the input port of the N9340B and perform
this demonstration using ambient signals, such as from several local radio
stations. In this case you may need to jump ahead to Section 6 to learn how to
lower the noise.
