One 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)/f(i) = 2^(1/n); n=1,
3, or 12; Where 1000 Hz is the reference for 1/1, 1/3 Octave, and 1000*2^(1/24) Hz is the reference
for 1/12 octave. The marker returns the ANSI standard preferred frequencies.
Accuracy
1 Second Stable Average
Single Tone at Band Center: ≤ ± 0.20 dB
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
