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.
