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. |
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, up to 6 different input modules, an I/O
module and microphone power supply.
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 already 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. |
|
|
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 Std is as standard equipped with one input. 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.
P630 Std is a discounted version of P630 Pro
Some of the reduced or removed functions are:
Output Compress, Loudness test, 3-limit test, F-ave test, S-ave
test, Barcode, Filter Channel C, Secondary Phase test, Secondary THD test,
Bl test (voice coil offset), Cpk / Ppk analyze, T/S function, Test points (fixed to 250), Spectrum,
External power amplifier, 20 Volt output (optional), Sound by, Print
by, Repeat by Reject and Log manager.
