P630 Light

PC platform: Windows 10, Windows 8.1, Windows 8, Windows 7.

With its fast test time and high performance the P630 are very cost-effective in a fully automated environment. In less than 1 seconds it performs measurement of 500 different frequency points and tests parameters as frequency response, sensitivity, polarity, Rub & Buzz, THD, impedance, resonance, Q and F (Fres/Q). Each test data from the measurements are saved for future statistics and post-processing.

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 3 different input modules, an as optional a 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 Light 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. Furthermore I/O module and external key-box can be added to enable external control and interfacing.

All necessary hardware, cables and software etc. are included in a standard delivery except for suitable microphones and PC.

P630 Light is a discounted version of P630 Std.
Removed functions are:
System multiplexing - only one output connection.
