SUNLIGHT AUDIO SWEEPER 7116C Loudspeaker Polarity Tester 139B NOISE GENERATOR 8121C GAUSS METER 138 IMPEDANCE METER 152A DIGITAL HIGH-SPEED Fo METER 7117 C.
Model 7117C has the following two main functions: A.Model-7117C can measure the Fo value of a loudspeaker fully automatically, with no need for manual adjustment of the instrument. The correct Fo value of a loudspeaker is displayed on the DISPLAY PANELã??( 14 ) in just 1 to 1.5 seconds. It has many advantages to using a voltmeter with a needle indicator for measuring the Fo value of a loudspeaker: ( a ) Easy to read; ( b ) No visual error; ( c ) High accuracy. B. Model-7117C can be used in a production line: high speed judging if the Fo value of every loudspeaker is within the qualified range, Judging speed is as fast as in just 0.3 to 0.7 seconds, the â?? PASS / FAIL Testâ?? functions will be indicated instantly. Technical specificationï¼? A. Display: Displayed in 3 �¾digits. B. Accuracy: Fo readout error less than �± ( 1% + 1Hz ) C. Measuring Range: 4 ranges from 16Hz to 3KHz, ( a ) 16Hz - 80Hz ; ( b ) 54Hz - 270Hz. ( c ) 180Hz - 900Hz ; ( d ) 600Hz - 3KHz. D. Fo measuring voltage added on the pre-measure loudspeaker: 1V r.m.s. �± 10%( complies with EIA standard ). E. Can test the impedance of an under-testing loudspeaker: Divided into two ranges, which are (1) 3�© to 18�©; (2) 19�©to 100�©. F. Measuring Speed: ã?? Fo Readout ã??in 1 to 1.5 seconds. ã??PASS / FAIL Testã??in 0.3 to 0.7 seconds. G. Limit Setting: Both the upper & lower limits of a loudspeaker can be preset independently from 16Hz to 3KHz, and have no interference with each other. H. Limitation in usage: Model-7117C can not be used to measure the Fo value of an air suspension loudspeaker, including those loudspeakers which are air-tight frames, since their Q.o. values are too low to measure.

Model-8121C uses a logic circuit to generate Pseudo Random Noise, it is the newest and the most advanced design to generate audio white noise. It has a much flatter frequency response than using a diode. Model-8121C has: (1)White noise source. (2)Weighting filters. (3)Built-in power amplifier. (4) TRUE RMS voltage meter circuit. It can generate five different kinds of the noise spectrum, including White Noise, Pink Noise, and three kinds of Weighted Noise, that conform to the following nations standards:(1) JIS C5531, IEEE 219, CNS 4785 (2) EIA 426B(3) DIN 45573 1. White Noise: -3dB Bandwidth: 20Hzï½?100kHz, Roll off:-24dB / Oct. Flatness: �±1dB 2. Pink Noise: -3dB Bandwidth: 20Hzï½?20 kHz Roll-off: -24dB / Oct. Crest factor: 4 ( IEEE 219 ) Amplifier: 1.100W output is defined at an unclipped maximum output of sine wave. 2.Frequency response : 20 Hz~20 kHz ±0.2dB; 20 kHz~100kHz ±1dB 3.
