Digital Television Signal Analyzer Measurement Guide : ISDB‑T Signal Analyzer : Delay Profile Information Display (Custom)
 
Delay Profile Information Display (Custom)
Delay Profile is the selected measurement display format. The Marker function is Off.
Modulation Analysis – Delay Profile Measurement Display
The Marker function is On, and the Marker menu shows that the Delay Profile (Zoom) graph is using the active marker.
Marker Enabled in Delay Profile (Zoom) Graph
The Marker function is On, and the Marker menu shows that the Delay Profile (Zoom) graph is using the active marker.
Marker Enabled in Delay Profile (Zoom) Graph
The blue range (visible in the Delay Profile (All) graph) shows signals that are delayed less than 0 µs if the largest signal (not necessarily the least delayed) is set at 0 µs. In both Delay Profile graphs, the yellow area shows delayed signals that are within the Guard Interval, and the magenta area shows signals that are delayed beyond the Guard Interval (which are potentially problematic). For more configuration details, refer to section Delay Profile Configuration.

The formula to calculate the distance is as follows:
Distance = Delay Time × Velocity of Light (which is 2.99792 × 108 m/s)
