The N934xC HSAs provide powerful marker functions. In 
addition to normal and delta marker modes, the instru-
ment marker system provides noise markers, frequency 
counter markers, AM/FM tune and listen, and band power 
measurement. For the AM/FM tune and listen feature, the 
AM/FM demodulated audio can be heard with the internal 
speaker or the provided headphone. Speaker volume and 
delay time can be adjusted to meet your specific needs.
In this demonstration, we will perform an AM/FM tune and 
listen measurement using an external AM/FM antenna.
