Analysis
DETECTORS
Parallel Detectors: On every measurement:
A- or B-weighted: (Switchable) broadband detector
channel with three exponential time weightings (Fast,
Slow, Impulse), one linearly averaging detector and
one peak detector
C- or Z-weighted: (Switchable) as for A- or B-
weighted
Overload Detector: Monitors the overload outputs of
all the frequency weighted channels
MEASUREMENTS
X = frequency weightings A or B
Y = frequency weightings C or Z
V = frequency weightings A, B, C or Z
U = time weightings F or S
Q = exchange rate 4, 5 or 6 dB
N = number between 0.1 and 99.9
