LMS, LX500, speaker test instrument

LMS loudspeaker measurement system

Speaker PC test system consists of a ISA card, RS232 interface cable, Windows application software, and a M31 microphone calibration based (standard). QC can be used for testing, the speaker speaker design and development, as well as a variety of general acoustic measurement. Its rich graphical user interface makes the function of convenience and the operation of the system is greatly enhanced. Is ahighly cost-effective acoustic analysis system, high quality data can be provided forthe actual acoustic engineering application, and the strong function of the computerbased, pay special attention to meet the unique requirements of speakers to develop and test QC, is the most ideal tool for professional sound system, home audio systems, car audio, audio engineering acceptance.

The hardware of the system:

LMS consists of a low distortion sine wave oscillator, bistable tunable tracking filter,microphone preamplifier, gated peak / average level detection circuit. Containing a set of line level output, balance line input and active microphone input. From thefour methods for measuring the optional, external microphone preamplifier for level calibration, testing frequency range from 10Hz to 100KHz, and 16 bit 90dB digital audio dynamic range. This system has very high resolution, the 10Hz allows for up to 200 logical space frequency data point, quite a data point to each pixel on the screen. Dual trace filter can be flat, low pass, high pass, band-pass and band stopseveral response measurement method. The measurement accuracy of the systemand the flexibility and other expensive several times comparable, the veteran or novice and experienced, are easier to set up and operate.

Systems software.

Eight measurement modes:

Voltage, SPL, RT60, impedance, inductance, capacitance, voltage, pole figure.

All of the hardware features of LMS can be controlled and modified by the parserParameters dialog box, can also be used as a fast setting file on disk for future calls to the control panel parameters. 10Hz to any frequency within 100KHz sweep,sweep precision from 2 to 800 points available.

All graphics are in WYSIWYG design in a drawing board. Screen display and print output. The user can fully control the various design elements of graphics, including fonts, colors and lines of type. Custom graphics file system also provides input the project name, personnel, and the company name, but also with the notes thegraphical layout and the matters needing attention region. The use of any standard Windows printer, driver, can support high resolution panchromatic print
