SNR Graph View
Display 11 shows the SNR bar graph view. These are the signal-
to-noise ratio (SNR) test results which are displayed as the
emissions and noise floor are measured. Each column
represents one DP test frequency or TE frequency band. The
height of each column represents the SNR measured.
When a protocol with a “PASS” criterion has been selected, the
user will see a horizontal green line at the decibel level
corresponding to the SNR required for a pass. Green vertical
bars represent a pass, a yellow bar is a non-Pass at the
frequency band.
NOTE: Diagnostic protocols can display green or purple bars.
Green is displayed when a “PASS” criterion is set in the device.
For more information on this see
Setting the PASS SNR Level on
page 44.

Value Graph View
Display 12 shows the Value graph view for right ear test. Red
circle symbols represent the absolute emission levels at each DP
test frequency or TE frequency band. For the left ear, dark blue
“X” symbols will represent the absolute emission levels at each
DP test frequency or TE frequency band. White upside-down
triangles represent the noise floor at each DP test frequency or
TE frequency band.
Refer to page 41 for instructions to switch the default setting of
the graphs between the SNR Bar Graph and Value Graph.
