Detailed Operation
33
•
Reset Peak Hold - Resets the value shown in the numeric Peak indicator.
• Screenshot to USB - Copies the current screen to a timestamped PNG file and
stores it to an installed USB thumb drive.
4.2.3
EBU Meter Settings
•
EBU Scale - +9 scale displays loudness from -18 to +9LU and +18 scale displays
loudness from -36 to +18LU.
•
Input Gain - /-24dB of gain to be applied to audio inputs. For conve-
nience, this is a duplicate of the adjustment in ITU Meter Settings, and adjusting it
in either place will control the same attenuator.
•
Integrated Measurement - Start/Stop the EBU integrated meter.
•
Peak Hold Time - Sets how long the peak meter will hold the last peak value. De-
fault is 3 seconds.
•
Apply Loudness Measurement - Apply the automatically calculated difference be-
tween the loudness measured by the EBU Integrated meter and the target value as
an offset to Input Gain (i.e. the same number shown by the top right numerical
readout). Note that this can be done automatically by pressing the F3 front panel
key when GPI is enabled.
•
Save Log to USB - Saves a “session” log to USB which contains time-stamped CSV
formatted loudness data. The data is started when the meter is started, and stops
when the meter stops. Reset clears the data.
NOTE: Resetting loudness measurement will clear the current data for session log-
ging. If you want to keep this data, be sure to save to USB first!
•
Reset Loudness Measurement - Clears the integrator for all meters, does not reset
Input Gain. Note that except for a setting of Infinite, all integrators are self-clear-
ing once their time elapses (so about 30 seconds for an integration time of 30 sec-
onds).
•
Reset Peak Hold - Resets the value shown in the numeric Peak indicator.
4.2.4
RTA Options:
•
1/3 octave/1/6 octave - sets the analyzer to 30 bands or 60 bands. Typical mea-
surements require only 1/3 octave resolution.
•
RTA Source - Select the input for the RTA
