Audio FM收音机电性能测试指导书

AudioFM收音机电性能测试指导书目的:验证FM广播收音机产品的电声性能是否符合规格要求。

1.适用范围适用于调频广播接收机包括调谐器组合机中的调频收音部分进行电声性能的测量。

2.定义无3.职责无4.测试程序5.1 标准测试条件5.1.1 标准调制度标准调制度是指调制信号的峰值频偏与系统最大频偏的百分比。

标准调制度规定为30%。

5.1.1.1 标准立体声调制度100% 调制度对应于±75KHz频偏。

30%调制度对应于±22.5KHz频偏。

5.1.1.2 标准立体声调制度设整个立体声复合信号的调制度为100%(±75KHz频偏)其中:导频信号占10%(±7.5KHz频偏)主、副信号的合成信号占90%(±67.5KHz频偏)以此主、副信号的合成信号作为100%(±67.5KHz频偏) ,那么,30%的调制度则为±20.25KHz.对于不同的调制方式,其频偏的分配如下表所示。

5.1.2 标准测试频率测试频率规定为:88、98、108MHz。

标准测试频率规定为:98MHz。

客户有不同要求时按客户要求执行。

5.1.3 标准输入信号电平标准输入信号电平规定为71dBf(≈66dBuV/EMF)5.1.4 标准负载测量电性能时应该用阻值等于扬声器标称阻抗的纯电阻(误差为 2%)代替扬声器做负载测量声性能,且应按扬声器的标称阻抗计算相应的电压值。

5.1.5 标准输出功率接收机的输出用加到扬声器上的功率来表示或者用标准负载上所消耗的功率来表示。

根据接收机的类别一般可用5mM 10mM 50mM和500mM 作为标准输出功率,其中50mM为优选值。

对于更大功率输出的接收机,可用比标称有用功率低10dB的功率作为标准输出功率。

根据公司产品的特点,一般定义为1W,产品规格有定义的,以产品规格为准。

5.1.6 音效处理功能的设置1)均衡(BALANCE EQUALIEER),低音(BASS)和高音(TREBLE)旋钮置于中心位置;2)音调(回音/ECHO、变调/KEY/TONE等)控旋钮置于中心位置,软件调节的应处于不影响音频特性输出的位置;3)环绕(SURROUND)、升频/降频(UP SAMPLING /DOWN SAMPLING)等声场处理功能关闭。

• Crosstalk - Signals from one channel leaking into another channel. Normally, this happens between left and right stereo channels. - A generator drives one channel and this channel's output value is noted; meanwhile the other channel is set for zero volts. The measured channel left open. - Whatever signal is induced into the tested channel is measured at its output with an rms voltmeter and noted. A ratio is formed by dividing the unwanted signal by the above-noted output test value, and the answer expressed in dB.
- XLR plugs and sockets are used mostly in professional audio and video electronics cabling applications. Home audio and video electronics normally use RCA connectors.

AudioTools软件简要操作说明

AudioTools软件简要操作说明李广编写Version 20130222 1.软件简介:AudioTools是由美国Studio Dix Digital公司独家开发的,基于Apple移动平台的专业声学/电子测量软件。

该软件通过外接IAudioInterface2 (简称IAI2)转接适配器来实现高精度声学测试。

Studio Dix Digital的首席工程师Andrew Smith曾就职于美国著名的测试仪器公司Sencore,并开发了Sencore家庭影院声学测试套件。

AudioTools软件在研发期间得到HAA主席Gerry Lemay的大力支持,使得该软件完全支持HAA家庭影院调试流程并能和HAA A VPro2.0调试报告软件无缝衔接,通过WiFi 网络快速将调试数据导入报告软件中。

AudioTools软件可以在Apple的APP商店付费下载,基本模块价格为128元人民币。

HAA家庭影院声学调试需要再购买以下几个附件模块:1.SPL Pro 数字声压表(多声道声压校准)2.ETC 能量时间曲线(RT60)3.Polarity 扬声器相位测试4.Surround Signal Generator 环绕声信号发射器(Dolby Digital5.1/DTS6.1)图1.

1前言直到现在,GSM网络的最主要基本业务仍然是语音业务,语音质量的好坏直接影响用户对于运营商的选择;另外,随着移动网络发展的日趋成熟,客户对网络的性能质量要求逐渐提高。

因此,根据电信网络服务质量(QoS) 的要求,建立一套客观评估标准,如何更好地对网络的语音服务质量进行定量分析和测量就逐步摆在了网络运营商的面前。

语音服务质量的测量与通常移动网络的信号质量测量有很大的区别。

在GSM网络中,对无线质量的评价是通过RxQual 来实现的。

但是语音在GSM网络中是经过信道及信源编码的,而RxQual 只能描述空中接口的传输质量,并不能给出终端用户对无线网络的实际感受,语音服务质量的测量将更好地反映用户对网络的真实感受情况。

本文将就语音QoS的测量方法进行较深入地讨论。

2 语音质量测量和量化标准的发展史目前语音QOS测试方法主要有主观测试方法和客观测试方法两种,ITU-TP.800定义了MOS的主观测试方法,客观测试方法主要有:PSQM、PSQM+、PESQ等。

其中ITU-TP.862(PESQ)是目前ITU推荐用于端对端网络语音质量测试的方法。

早期语音质量的评测主要采用主观评分的方式:调查用户被要求按照1-5分对接收到的电话语音质量进行评分(5表示最好,1表示最差)。

音频测试简介

音频测试简介

RFR曲线举例
手机听筒效果对使用者来说是比较关心的环节,一般情况下对频率响应曲线的 调整也只是针对手持模式RFR的调整。下边是几款手机的RFR曲线供大家参考。(注 意:过标准的曲线并不是声音效果最好的曲线,通常情况下,CTA标准曲线声音比 较尖锐,要想获得好的音质,需要重新调整RFR。)
M形状的RFR曲线使用较多.
侧音掩蔽值(STMR)
发送失真——测试方法
先在人工嘴的MRP 处产生1KHz音频使其在DAI的输入端呈现0dBm0 的讯号。 此讯号被校正为0dB ARL( Acoustic Reference Point )。 然后依照下例表格规定,其发送失真度不得小于其要求
发送失真
过CTA标准手机和生产手机在音频参数的区别:
图1
4)进入音频调试界面(如图2),选择Speech Input FIR Coeff(sfr调试) ,如图2所示, 按照表示顺序进行操作进入图3界面(测试sfr选择Tx,测试rfr选择Rx).
图2
图3
5)点击Load input File,将刚刚生成的sfr in.txt load进去,即可进入图4界面,根 据所测得的曲线图形在相应频点上调整增益值的大小,满足测试标准.
第二步:查看sending distortion 经验:SD fail可以通过将SFR 1KHz的频响往上拉的方式提高在1KHz的感度,
从而通过。 原因:SD fail会修改SFR,造成SLR/STMR改变
第三步:调整SLR/RLR/STMR STMR在SLR确定后调整。 原因:STMR会随SLR改变而改变
2.具体测试步骤如下: 1)首先将手机设置为normal音量,用UPL或UPV进行测试,生成音频测试报告. 2)将测试报告中SFR/RFR测得的100-4KHz的音频数据复制到一个Excel中,整理后保存 为sfr in.txt/ rfr in.txt格式,作为音频曲线调试的输入文档. 3)准备工作都已经作好,开始正式调试Байду номын сангаас 第一步调试SFR,首先选好端口,点击 Reconnect,选择Audio Tool.,如图1所示.

回路4-PriMic->EarReceiver如图1所示,回路④为测试PriMic->EarReceiver回路,PC控制手机打开PriMic 到EarReceiver的通路,通过声卡输出口3,接入仿真嘴发声,经过手机回路,由耳机左右声道接受信号,经声卡输入端口2进行采集,最终软件对采集信号进行分析输出测试指标结果。

Note:放大器前面如图2.2所示,后面板如图2.3所示:图2.2图2.3接线的时候,信号从前面板输入,后面板输出,并按照面板标识对应接线。
