Each graph can display up to 4 plots which can be of two different types, intensity and pressure or

coherence and PI index for example. The available data are:

• Intensity (dB, dBA, W/m² or W/m²(A)) – (Instantaneous or Time averaged)

• Leading edge probe

• Trailing edge probe

• Average leading edge / trailing edge

• Pressure (dB, dBA, Pa²(rms²) or Pa²(rms²)(A)) – (Instantaneous or Time averaged)

• Leading edge probe (mic A)

• Leading edge probe (mic B)

• Leading edge probe (average mic A / mic B)

• Trailing edge probe (mic A)

• Trailing edge probe (mic B)

• Trailing edge probe (average mic A / mic B)

• Average leading edge / trailing edge

• PI Index (dB, or linear) – (Instantaneous or Time averaged)

• Leading edge probe

• Trailing edge probe

• Coherence (dB, or linear) – (Instantaneous or Time averaged)

• Leading edge probe

• Trailing edge probe

• Speed (m/s, km/h, mile/h or ft/s) – (Instantaneous or Time averaged)

• Distance (m, km, mile or ft) – (Instantaneous or Time averaged)

Several presets are available from the top radio buttons:

• Intensity,

• Pressure,

• PI Index,

• Coherence,

• PI Index/ Coherence,

• Speed,

• Distance.
