信号发生器简易使用手册
信号发生器简易使用手册一、概述信号发生器主要的功能是在手机测试时提供符合要求的信号，因此我们在使用前要先了解信号发生器的一些基本的性能指标（如所能产生的信号频率范围、幅值范围等），选择符合我们要求的仪器来进行测试。
信号的频率范围一般都会标在仪器的前面板上，使用前应多加留意。
下面我们就以Agilent E4438C ESG V ector Signal Generator为例来说明信号发生器的基本使用方法。
二、基本项设置和功能1、显示屏显示当前功能的信息。
信息包括状态指示，频率和幅值设置，错误消息。
软键的标注位于显示屏的右手边。
2、软键软键激活显示屏上对应的每个键的功能。
3、频率设置键按这个键可以设置有关频率的功能。
例如改变RF输出频率或使用菜单设置频率的属性如参考频率和频率偏差等。
4、幅值设置键按这个键可以设置有关幅值的功能。
例如改变RF输出幅值或使用菜单设置幅值的属性如功率搜索，用户平面和电平模式等。
5、旋纽旋转这个旋纽可以增加或减少数值或改变高亮数字或性能。
也可以使用它来列表中单步移动或在一行中选择项目。
6、菜单键这些键可以通过软键设置列表扫描和单步扫描，有用功能，LF输出和各种调制类型等。
7、保存键通过这个键可以将数据保存到仪器状态寄存器中。
仪器状态寄存器分为10个序列（0～9），每个序列包括100个寄存器（00～99）。
保存键允许保存和重现频率和幅值设置。
一当仪器状态被保存了，所有的频率，幅值和调制设置可以通过Recall键重现。
8、重现键重现先前保存在寄存器里的仪器状态。
9、外部输入连接端口1这个BNC（同轴电缆接插件）输入连接端口接受AM，FM和√M ±1 V p的信号。
对于所有的调制方式，±1 V p 形成指示的偏移或深度。
当为AM，FM或√M选择ac_coupled输入，峰值输入电压偏离1 V p 3％时，显示屏上的HI/LO指示高亮。
破坏电压是5V rms和10V p。

为了实现黑白和彩色信号的兼容，色度编码对副载波的调制有三种不同方法，形成了三种彩色电视制式；即NTSC制、SECAM制和PAL制（对于NTSC制，由于选用的色副载波的频率不同，还可分为NTSC4.43和3.58两种）。
三种彩色电视制式的主要国家和地区：彩色电视机的制式现状 NTSC制：中国、墨西哥、日本、台湾、加拿大等国和地区采用；PAL制：德国、中国、香港、英国、意大利、荷兰、中东一带等国和地区采用；SCEAM制：中国、前苏联及东欧和非洲各国采用。

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.

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.
