The P630
generates sufficient power with the internal power amplifier
to energize all defects from air-gap problems, puffing
sounds, loose particles, constrained voice coil, cabinet
rattling, litze wire clatter, glue problems etc., which
generally speaking are known as Rub & Buzz distortion.
P630 are able to measure microphone
frequency response due to the built-in output compress
function. This enables a constant signal pressure even from
a standard loudspeaker.
Note picture show old B&K input plugs. Standard input plugs
are of Lemo type.
|
The system consists of a service friendly 19" P600
cabinet with standard sized modules plus a PCI card with 4 x 24 bit
A/D & D/A converters and a PCI I/O card to control the cabinet.
The cabinet contains protected 15 volt rms. power amplifier
(optional 20 volt rms.) , up to 6 different input modules, an I/O
module and microphone power supply.
On request it is possible to install a
digital power amplifier with a output of max 48 V rms, 600 VA,
30 A peak.
The software is arranged in four modes, an operator mode, a
technician mode, a global set-up mode, and a utility mode, which all
are protected by passwords.
|
|
The operator mode is for
day-to-day production testing of parameters alfaready set-up
in the technician mode. This mode is specially designed for
non skilled personnel or for fully automated operations.
|
|
|
In the technician mode all
parameters as frequency range, test level, reference curves
limits, Rub & Buzz and THD filters etc. are customized to
the specific requirements for each individual test.
|
|
|
In the global
set-up the graphical presentation, test control, paths for
files, chain of tests, statistics etc. are defined in the global
set-up the graphical presentation, test control, paths for
files, chain of tests, statistics etc. are defined.
|
|
|
For
post-processing and manipulation of stored data there are a
number of Utility functions as Export and Import of data,
Statistical analysis and graphical display of batch data
etc. The statistical analysis including calculation of
various numbers of standard deviation and average curves to
determine the test limits. The analysis is able to find a
best matched measured unit against the average or another
unit.
|
The P630 is as standard equipped with two inputs. There are as
standard four analyzing channels, one for frequency response, one
for impedance and two for distortion / Rub & Buzz. Extra inputs (up
to six) can be added to the system.
All necessary hardware, cables and software etc. are included in
a standard delivery except for suitable microphones and PC.
