Excitation Options
- Excitation Presends
When measuring an acoustic space, it is often desirable to sufficiently excite that space before commencing
a measurement. The number of pre-sends specifies how many times the selected excitation noise sequence should
be output before the measurement begins. Each pre-send is equal in duration to the current measurement duration.
- Invert Ch 1/2 Polarity
The polarity of either or both output channels may be inverted. Inverting one of the two channels enables
the two output signals to be combined as a single, balanced signal for higher output voltage when applied
to the balanced input of a mixer or amplifier.
