Advance marker functions

The N934xC HSAs provide powerful marker functions. In addition to normal and delta
marker modes, the instrument 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.
