two measurements, which is the signal-to-noise ratio (also called S/N
or SNR). This automatic mode can be particularly convenient when
making adjustments to a device-under-test to maximize signal-to-noise
ratio.
Each measurement function remembers its settings, so returning to that
function will invoke the same filter and detector options. Operating
convenience for many users is enhanced by setting up Noise and
Amplitude functions with different filter and detector selections so that
noise can be measured to two different standards simply by pressing
the AMPL/NOISE button twice.
Level
The Level function is selected by pressing the FUNCTION LEVEL key.
The Level function is used to measure the amplitude (level) of two
input channels simultaneously, using true RMS detection. The level of
the selected input channel is shown in the top left of the display. The
level of the alternate channel is shown in the top center of the display.
