The available Advanced View graphs depend on the current scopes.

Press to toggle between different Advanced View graphs.

The first two graphs are available for all scopes.

This graph is similar to the Simple View, the only difference being that functions L_W, I_eq and L_eq are displayed simultaneously.

This graph presents the F_pI-function (L_eq - I_eq) along with the dynamic capability (L_d) obtained from the last probe calibration or verification.

L_d = ∂_pI0 - K, where K is either 10 dB or 7 dB for accuracy Engineering or Survey, respectively.

∂_pI0 is the F_pI measured when the probe is exposed to a sound field which is exactly the same for both microphones.

This graph is only available for the Segment Scope.

∆I_eq: The difference between Ieq in Horizontal and Ieq in Vertical scan. Negative direction value indicates that the direction is opposite in H vs V.

∆L_eq: The difference between Leq in Horizontal and Leq in Vertical scan

s: The uncertainty in dB given by the ISO 9614-2 standard.

For Engineering accuracy, ∆I_eq(b_i) ≤ s(b_i), where b_i denotes frequency band i.

This graph is only available for the Total Scope.

F_+/-: The extraneous noise indicator defined by the ISO 9614-2 standard.

For Engineering accuracy, the requirement is F_+/- ≤ 3 dB.

For Survey, there is no requirement.
