SR785 Dynamic Signal Analyzer
Octave Channels
Select the number of input channels for the octave measurement. The number of Octave
Channels affects the Measurements of both displays.
If 2 Octave Channels are selected, then both inputs may be analyzed. The Measurements
of both displays are independent. The Highest Band for all Octave Resolutions is
decreased by 2 in this case.
If 1 Octave Channel is selected, then only one input may be analyzed. If both displays are
making an octave measurement, they must both use the same input. Changing the input
of the active display will change the Measurement or input of the other display if
necessary. User Functions which use both inputs may not be measured. Choosing 1
Octave Channel may change the current Measurements so that both displays use the
same input.
