2015-P/J数字万用表

我们的音频分析万用表将音频带质量测量和分析与多用途 6½ 位 DMM 集于一体，一切尽在一台半机架仪器中。 它们可以测量 20 Hz 至 20 kHz 音频带范围内的总谐波失真 (THD)，还可以计算总谐波失真+噪声和信纳比 (SINAD)。 2015P 和 2016-P 设备可直接识别频谱峰值。 2016 和 2016-P 音频分析数字万用表的正弦波发生器输出是 2015 音频分析数字万用表的两倍，适用于要求测试信号大于 8 Vrms 的应用。

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
