Basic Info.
Product Description
Use for Testing the spurious noise of the loudspeaker,headphone,loudspeaker system ... etc., suitable for use in production line, R&D, quality control and incoming parts inspection department.
Low Distortion Sine Wave
THD<=0.15%, 20Hz~20 kHz. Best suitable for testing the spurious noise of the SPK. and other electroacoustic components.
Digital Display Voltmeter and Frequency Counter, complies the need for precise test.
Has both manual and auto logarithmic sweeps. Allows random setting of start/stop frequency for sweep range.
Simple to operate, non-experts can operate.
Four kinds of built-in power amplifier which are optional to buy. ( 20W, 60W, 100W & 200W ). All designed with triple protection circuitries which permit long-term short circuit. ( 200W includes both of Model-7116D and Model-160PD )
High resolution ( 0.001V ) voltmeter :
Low voltage needed in testing the receiver & headphone can be obtained precisely by using coarse & fine volume control.
With the supplement of frequency fine adjustment, the precise lowest resonant Fo value of Loudspeaker can be easily obtained.
Excellent reliability :
With the accumulation of more than 20 years experience in professional design, 7116C has ultra low faulty rate, high reliability, can sustain whole day continuous testing.
