This statement identifies conditions or practices that could CAUTION result in damage to this product or other properties. WARNINGThe following terms and symbols may appear on the product: This term indicates an immediately accessible injury hazard. DANGER This term indicates that an injury hazard may occur, but is WARNING not immediately accessible. This term indicates potential damage to this product or other CAUTION properties.!DANGER High voltage Protective Conductor Terminal ATTENTION refer to manual Double Insulated DANGER Hot surface Earth Ground Terminal(2) Do not place any heavy objects on the instrument under any circumstances.(3) Disassembling the instrument Due to the precision of this instrument, all the procedures of disassembling, adjusting, and maintenance should be performed by a professional technician. If the instrument has to be opened or adjusted under some unavoidable conditions, and to be managed by a technician who is familiar with GFG-3015. Once there is any abnormality, please contact our company or our distributor near you. (4) Power Supply AC input should be within the range of line voltage±15%, 50/60Hz. To prevent the instrument from burning up, be sure to check the line voltage before turning on power.p. 2GFG-3015(5) Grounding!WARNINGTo avoid electrical shock, the power cord protective grounding conductor must be connected to ground.GFG-3015 can be operated only with an earth grounded AC power cord that connects the case and ground well. This is to protect the user and the instrument from the risk of shock hazard. (6) Fuse Replacement!WARNINGFor continued fire protection, replace fuse only with the specific type and rating by qualified personnel. Disconnect the power cord before replacing fuse.The fuse blows only when there is any wrong on the instrument, which will stop working under this situation. Please find out the cause, then open the outside case (Please see the Figure (A), Figure (B) on below) and replace a proper fuse as listed below. Be sure to use the correct fuse before changing the applying location. F101 : T 0.8A/250V F100 : T 0.5A/250V Check the line voltage setting on the rear panel. If the line voltage setting does not match, Please change the line voltage setting according to the following steps: 1. Remove line cord from AC socket. 2. Switch the “AC line voltage switch” to correct setting with flat-blade screwdriver and reinsert.Figure (A) (7) Cleaning the Cabinet Disconnect the AC power cord before cleaning the instrument.Figure (B)Use a soft cloth dampened in a solution of mild detergent and water. Do not spray cleaner directly onto the instrument, since it may leak into the cabinet and cause damage.

(10) For United KingdomAs the colours of the wires in mains leads may not correspond with the coloured markings identified in your plug/appliance, proceed as follows: The wire which is coloured Green and Yellow must be connected to the Earth terminal marked with the letter E or by the earth symbol or coloured Green or Green and Yellow. The wire which is coloured Blue must be connected to the terminal which is marked with the letter N or coloured Blue or Black. The wire which is coloured Brown must be connected to the terminal marked with the letter L or P or coloured Brown or Red. If in doubt, consult the instructions provided with the equipment or contact the supplier. This cable/appliance should be protected by a suitably rated and approved HBC mains fuse; refer to the rating information on the equipment and/or user instructions for details. As a guide, cable of 0.75mm2 should be protected by a 3A or 5A fuse. Larger conductorsNOTEThis lead/appliance must only be wired by competent persons.WARNINGTHIS APPLIANCE MUST BE EARTHEDIMPORTANTThe wires in this lead are coloured in accordance with the following codes: Green/Yellow :Earth Blue :Neutral :Live Brownwould normally require 13A types, depending on the connection method used. Any moulded mains connector that requires removal/replacement must be destroyed by removal of any fuse and fuse carrier and disposed of immediately, as a plug with bared wires is hazardous if engaged in a live socket. Any re-wiring must be carried out in accordance with the information detailed in this section.(Phase)p. 4GFG-30152. Product IntroductionThe frequency feedback method applied by GFG-3015 is a new technique that generates stable output frequency with extraordinary accuracy for Function Generator. The traditional function generators typically use integrating circuit and constant current circuit techniques that are easily affected by operation temperature or the quality of resistor or capacitor and other key components to occur poor frequency accuracy. The innovative design for GFG-3015 is to get rid of these problems. The frequency feedback system needs a compatible, powerful frequency counter. GW has designed his own full-function counter chip, GFC-9701, for this system with high frequency test range and full functions, including Period test, Duty test, Ratio test, Time interval, Pulse wide, direct display and direct connect with CPU system. GFG-3015 uses this Chip to read output frequency value at any time. Then CPU will modify the correct value of D/A converter immediately according to this value, so that the user can get a high accuracy frequency from GFG-3015 Function Generator. Besides, the GFG-3015 can also generate a high accuracy frequency to provide high frequency resolution.Graph1 indicates the fundamental construction of a frequency feedback system.D/A ConvertorVCOAMPO/PUser InterfaceCPUCounter (GFC-9701)Except the different design from the typical circuit, GFG-3015 system also has micro controller (CPU unit) equipping an additional RS-232 interface functions which will be used on any test system with other instrument or to be controlled by computer.GFG-3015p.53.

信号发生器的使用条件及操作规程

信号发生器的使用条件及操作规程信号发生器的使用条件信号发生器又称信号源或振荡器，在生产实践和科技领域中有着广泛的应用。

各种波形曲线均可以用三角函数方程式来表示。

能够产生多种波形，如三角波、锯齿波、矩形波（含方波）、正弦波的电路被称为函数信号发生器。

一、信号发生器的分类：1、正弦信号发生器：正弦信号紧要用于测量电路和系统的频率特性、非线性失真、增益及灵敏度等。

按频率覆盖范围分为低频信号发生器、高频信号发生器和微波信号发生器；按输出电平可调整范围和稳定度分为简易信号发生器（即信号源）、标准信号发生器（输出功率能精准地衰减到—100分贝毫瓦以下）和功率信号发生器（输出功率达数十毫瓦以上）；按频率更改的方式分为调谐式信号发生器、扫频式信号发生器、程控式信号发生器和频率合成式信号发生器等。

2、高频信号发生器：频率为100千赫～30兆赫的高频、30～300兆赫的甚高频信号发生器。

一般接受LC调谐式振荡器，频率可由调谐电容器的度盘刻度读出。

紧要用途是测量各种接收机的技术指标。

输出信号可用内部或外加的低频正弦信号调幅或调频，使输出载频电压能够衰减到1微伏以下。

3、微波信号发生器：从分米波直到毫米波波段的信号发生器。

信号通常由带分布参数谐振腔的超高频三极管和反射速调管产生，但有渐渐被微波晶体管、场效应管和耿氏二极管等固体器件取代的趋势。

仪器一般靠机械调谐腔体来更改频率，每台可覆盖一个倍频程左右，由腔体耦合出的信号功率一般可达10毫瓦以上。

4、扫频和程控信号发生器：扫频信号发生器能够产生幅度恒定、频率在限定范围内作线性变化的信号。

在高频和甚高频段用低频扫描电压或电流掌控振荡回路元件（如变容管或磁芯线圈）来实现扫频振荡；在微波段早期接受电压调谐扫频，用更改返波管螺旋线电极的直流电压来更改振荡频率，后来广泛接受磁调谐扫频，以YIG铁氧体小球作微波固体振荡器的调谐回路，用扫描电流掌控直流磁场更改小球的谐振频率。

扫频信号发生器有自动扫频、手控、程控和远控等工作方式。

轻松使用HDMI：HDMI-VGA和VGA-HDMI转换器

轻松使用HDMI ：HDMI-VGA 和VGA-HDMI 转换器作者：Witold Kaczurba 和Brett Li在消费电子市场，电视、投影仪和其它多媒体设备纷纷采用高清多媒体接口(HDMI ®)技术，使得HDMI 成为全球公认的接口。

相信不久之后，所有多媒体设备都需要配备该接口。

HDMI 接口在家庭娱乐中已经广为流行，近来在便携式设备和汽车信息娱乐系统中，它也日渐风行。

实现标准化多媒体接口是竞争高度激烈的消费电子市场的必然要求，上市时间对于该市场而言至关重要。

除了提高市场认可度以外，采用标准接口还能大大改善投影仪、DVD 播放机、高清电视以及不同制造商生产的其它设备之间的兼容性。

然而，在某些工业应用中，从模拟视频向数字视频过渡所需的时间比消费电子市场要长，许多设备尚未采用新的数字方法来发送合成音视频数据。

这些设备仍然使用模拟信号作为唯一的视频传输途径，原因可能是特殊市场或应用有特定要求。

例如，对于投影仪，有些客户仍然偏好使用视频图形阵列(VGA)电缆，而其它一些客户则使用音频/视频接收器(AVR)或媒体盒作为集线器，将一条HDMI 电缆连接到电视，而不是一组凌乱且不美观的电缆，如图1所示。

图1. 媒体盒将模拟信号转换为HDMI新使用者可能认为HDMI 是一种相对较复杂的标准，需要经过验证的软件驱动器、互通性和兼容性测试，从而保证一种设备与其它各种设备结合使用时能够正常工作。

这似乎有点难以把握，遇到新技术时常常会发生这种情况。

然而，先进的半导体技术正在解决这些难题，模拟域和数字域均实现了改进，包括通过更高性能的模块来均衡较差的差分信号，以及利用更复杂的算法来减少软件开销和纠正位错误。

本文说明先进的半导体解决方案和灵巧的软件如何帮助实现HDMI 。

两种基本器件——HDMI-VGA (“HDMI2VGA”)和VGA-HDMI (“VGA2HDMI”)转换器——为熟悉视频应用的工程师提供一种简单的模拟视频与数字视频相互转换的方法。
