Select the following test sources from the Signal list:

• Pink Noise: Pseudorandom noise with equal energy per octave.

• Sine Wave: Use the slider to adjust the frequency or type a value in the range

20 Hz - 24 kHz. Use the Level1 up/down arrows or type a value in the field in

the range -96-0 dB. The Level2 and Freq2 controls are disabled.

• Dual Sine: Use the sliders to adjust the frequencies for both Sine Waves or

type values in the range 20 Hz - 24 kHz. Use the Level1 and Level2 up/down

arrows or type values in the fields in the range -96-0 dB.

• Pink Sync: Synchronous noise with equal energy per octave. The sequence

repeats every FFT-sized interval.

• Pink Sweep: Synchronous wept sine wave with pink spectrum. The sequence

repeats every FFT-sized interval. The amplitude falls off 3 dB/octave resulting

in equal energy/octave.

Smaart 6 generates mono signals and sends them to one or two output channels, as

selected in Audio I/O options. Even so, we recommend using only one channel and

physically splitting the signal outside the computer to the reference and measurement

signal branches for Frequency Response and Impulse Response measurements. The

main reason is that there is often a small but measurable time offset between the left and

right output signals that could cause problems in phase and delay measurements. Also,

when you split the signal inside the computer, you can never be absolutely sure the

reference signal was exactly identical to the signal sent through the SUT.
