THD+N
THD+N measurement provides a single value measurement of the THD+N (Total Harmonic
Distortion with Noise) in the output signal from each DUT channel, as measured at each of
the analyzer input. The THD+N measurement settings allows you to configure the signal
generation settings and signal analysis settings.
The result for the THD+N measurement for all the selected channels are displayed in a bar
chart (SINAD, THD Level, THD Ratio, THD+N Level, and THD+N Ratio). Refer to
“Measurement Results” on page 399 for more information on the respective result menu
page. Use the arrow keys to navigate through the respective tabs and to display the menu
page.
