我們的音頻分析萬用表將音頻帶質(zhì)量測量和分析與多用途 6? 位 DMM 集于一體，一切盡在一臺半機架儀器中。 它們可以測量 20 Hz 至 20 kHz 音頻帶范圍內(nèi)的總諧波失真 (THD)，還可以計算總諧波失真+噪聲和信納比 (SINAD)。 2015P 和 2016-P 設備可直接識別頻譜峰值。 2016 和 2016-P 音頻分析數(shù)字萬用表的正弦波發(fā)生器輸出是 2015 音頻分析數(shù)字萬用表的兩倍，適用于要求測試信號大于 8 Vrms 的應用。

The characteristics of
advantage
Frequency domain analysis in conventional time domain instruments provides a wide range of measurement functions in a compact semi-frame instrument
Dual output audio with sinusoidal signal source
One output generates a stimulus signal, and a second output (as opposed to the first) simplifies testing the differential input circuit to achieve common mode or noise cancellation performance
Fast frequency scanning is used to quickly verify audio tape circuits in production test system
Distortion measurements can include up to 64 harmonic amplitudes that are programmed to calculate the number of harmonics to be included, optimizing the accuracy, speed, and complexity of a particular test
Five standard audio shaping filters filter electromechanical noise in the production shop or mimic other types of system transmission characteristics
The 13 digital multimeter features (6 bit) minimize the cost of additional equipment when configured with test Settings
