Main functions: 1) LMS system hardware: LMS from low-distortion sine wave oscillator, bistable adjustable tracking filter, microphone preamplifier, gated peak / average level detection circuit. Containing a set of line-level outputs, balanced line inputs with active microphone input. You can choose one of four methods for measuring, external microphone pre-amplifier can be used rhetoric level calibration, test frequency range from 12Hz to allow up to 200 logical spatial frequency data points, the equivalent of each pixel on the screen There is a data point. Dual trace filter can be flat, low pass, high pass, band pass and band stop several response measurement methods. Measurement accuracy and flexibility rationale can be comparable with other expensive times of the system, for novice and experienced veteran, are easier to set up and operate. 2) LMS system software: eight kinds of measurement modes: voltage, SPL, impedance, RT60, inductance, capacitance, voltage, pole figures. All hardware capabilities of LMS can be controlled and modified by the analyzer parameters dialog, set the file can be saved as a quick call to the control panel in the future parameters on disk for. Any frequency within 10Hz to 100KHz frequency sweep range, precision scanning points selectable from 2-800 points. All figures are in a WYSIWYG fashion design drawing board. Screen display and printouts same. Users can perform a variety of graphic design elements full control, including the type of font, color, and line. The system also provides Enter a project name, personnel, and custom graphics file name of the company, which also comes with a graphical layout comment area and precautions area. Use any standard Windows printer driver, can support high resolution full-color printing. LMS software written by the user macro control. LMS macro programming language can be used to write the screen prompts the operator to control the test scan, run the software tools to control graphics printing, output data, and perform pass / fail testing.
