2.16.3 Start, Stop and Reset Triggers
In order that Loudness measurement can be targeted towards specific programme content,
PAM1 is equipped with the ability to Start and Stop (pause) measurement cycles. These
functions can either be triggered manually from the on screen button or from a GPI via the D9
connector at the rear of the unit.
The action of restarting measurement after a ‘stop’ is executed recommences calculation of
Loudness from the previous value or values. This methodology ensures that programme
loudness measurement can be achieved outside of scheduled interruptions such as commercial
breaks or announcements . A means to integrate this could be to use studio or playout
automation to start/stop measurement via the GPI .
The Reset button discards any previously measured values enabling a new calculation to begin
once the Start button is activated once more.
2.16.4 Histogram Display and Integration Settings
The Display button within the Loudness Setup menu provides access to three integration modes
by which the resultant loudness level can be displayed as either a numerical value, moving line or
via the
Histogram .
The sample for all Loudness measurement is set internally at 400ms. The 3 modes of display are
as follows:

A 3 Second sliding window.

Integrated Measurement over the entire duration of any clip/programme. Control achieved via
the Start/Stop/Reset buttons (soft or GPI)

Gated: Similar to Integrated except that any sample lower than the -10dB gating level is
discarded.
