SNR

SNR measurement provides a single value measurement of the signal to noise ratio of the
output signal from each DUT channel. SNR is used to evaluate the intelligibility of a signal
by expressing the difference between the nominal signal level and the noise. SNR is formed
by two measurements where the first measurement is the signal level and the second
measurement is the noise level with the signal turned off. These two measurements are
expressed as ratio and displayed in decibels. The SNR measurement settings allows you to
configure the signal generation settings and signal analysis settings.
The result for the SNR measurement for all the selected channels are displayed in a bar
chart (SNR). Refer to "Measurement Results" on page
respective result menu page. Use the arrow keys to navigate through the respective tabs
and to display the menu page.
Signal generation
The signal generation is disabled if None is selected for the output configuration channel.
NOTE
The SNR signal generation settings menu page is displayed as shown in Figure 7-23.
