Radar Speed
Radar Speed controls how long time each radar revolution
takes.Selectfrom1minuteto24hours.Youmay“zoom”
betweenthesettings,aslongasthehistoryisn’treset.
PressingtheResetkeyresetsthemeteranddescriptor
history.
Radar Resolution
Radar Resolution sets the difference in loudness between
each concentric circle in the Radar between 3 and 12 dB.
Choose low numbers when targeting a platform with a low
dynamicrangetolerance.Youmay“zoom”betweenthe
settings,aslongasthehistoryisn’treset.
Low Level Below
Low Level Below determines where the shift between
green and blue happens in the outer ring. It indicates to the
engineerthatlevelisnowatriskofbeingbelowthenoise
floor.
Alert Indicator
Stereo Integrity
Theindicatorindicatesalackofstereointegritybased
on measuring the difference of left/right inputs. If there
is a consistent difference between left and right over a
prolongedtime,theLEDislit.
5.1Integrity
In this mode, Integrity is based on the signal levels on
L,R,C,LS and RS channels. If one or more of the channels
dropoutoveraprolongedtime,theLEDislit.
Stereoor5.1Integrity
Inthismode,IntegrityisgivenwheneitherStereoor5.1
Integrityaredetected.ThismeansthattheLEDislitwhen
neithervalidStereonor5.1signalsaredetected.
Off
The Alert indicator is disabled.
UnitedStates
Page11ofATSCA/85(May25,2011)referencesITU-R
BS.1770-1, even though BS.1770-2 was in effect at
thattime.Thesamepagealsosaysthat“Allreferenced
documentsaresubjecttorevision”.Thewordingis
ambiguousandit’suptothereadertodecidewhetheror
not a relative gate (the difference between BS.1770-1 and
BS.1770-2) is applied when measuring Program Loudness.
The“Leq(K)”settinginLM2disablestherelativegate,
whilethesetting“BS.1770-2”includesarelativegateat
-10LU.TheBS.1770-2settingisbetteracrossgenresand
forcontrollingloudcommercials.Checkinatwww.atsc.org
toseeiftheCALMacthasforcedATSCtomakeuptheir
mind.
TargetLevelinUnitedStatesis-24LUFS,measurement
gating not clearly defined.
Measure Scale
Thisparametercanbesettoeither“LoudnessUnits,LU”
or“LoudnessUnitsFullScale,LUFS”
When“LUFS”isselected,thenumbersintheouterringof
theRadarpageapply.When“LU”isselected,numbersare
shownarounda“0”denotingLUReference.
LU Reference
0LUEqualssetstheloudnessrequiredtoobtaina12
o’clockreadingontheouterring,whichisthesameasthe
borderbetweengreenandyellowontheRadarpage.0LU
is the reference to aim at.
Peak Indicator
Thisparametersetsatwhichlevelthepeakindicatorwill
beinvoked.
Setup
Momentary Range
EBU+9orEBU+18
Set range on the radar-meter
EBUmodemetersareabletodisplaytoshowtwodifferent
momentary displays: One with a narrow loudness range
intendedfornormalbroadcastanddenoted“EBU+9”,and
one with a wide loudness range intended for film, drama
andwiderangemusicdenoted“EBU+18”.
The“EBU+9”settinggivesamomentarymeterrange
from-18to+9LU,whilethe“EBU+18”settingsgivesa
momentaryrangefrom-36to18LU.
