Product specifications

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.
