1 to 12 octaves can be measured and
displayed.
1/1, 1/3, and 1/12 octave true center frequencies related by the formula:
f (i+1)				= 2	1 n	; n = 1, 3 or 12;
f	(	i	)

Where 1000 Hz is the reference for 1/1, 1/3 octave, and 1000 x2(1/24)Hz is the reference for 1/12 octave. The marker returns the ANSI standard preferred frequencies.

Accuracy	±0.2 dB
1 second stable average

Readings are taken from the linear total power spectrum bin. It is derived from sum of each filter.

1/3 octave dynamic range	>80 dB (typical) per ANSI S1.11 - 1986
2 second stable average, limited by input noise
