三 . 实验仪表设备1. 双踪⽰波器2. 数字万⽤表3. TPE-GP5通⽤实验平台4. G1N 实验模块5. G2N 实验模块四 . 电路特点及实验原理简介1. 电路特点本电路的核⼼是谐振功率放⼤器,在此电路基础上,将⾳频调制信号加⼊集电极回路中,利⽤谐振功率放⼤电路的集电极调制特性,完成集电极调幅实验。

当电路的输出负载为天线回路时,就可以完成⽆线电发射的任务。

为了使电路稳定,易于调整,本电路设置了独⽴的载波振荡源。

2. ⾼频谐振功率放⼤器的⼯作原理参见图 1。

谐振功率放⼤器是以选频⽹络为负载的功率放⼤器,它是在⽆线电发送中最为重要、最为难调的单元电路之⼀。

根据放⼤器电流导通⾓的范围可分为甲类、⼄类、丙类等类型。

丙类功率放⼤器导通⾓θ<900,集电极效率可达 80%, ⼀般⽤作末级放⼤,以获得较⼤的功率和较⾼的效率。

图 1中, V bb 为基极偏压, V cc 为集电极直流电源电压。

为了得到丙类⼯作状态, V bb 应为负值,即基极处于反向偏置。

u b 为基极激励电压。

图 2⽰出了晶体管的转移特性曲线,以便⽤折线法分析集电极电流与基极激励电压的关系。

V bz 是晶体管发射结的起始电压(或称转折电压。

由图可知,只有在 u b 的正半周,并且⼤于V bb 和 V bz 绝对值之和时,才有集电极电流流通。

即在⼀个周期内,集电极电流 i c只在 -θ~+θ时间内导通。

In this manual the word “WARNING” is used to indicate conditions or actions that may pose physical hazards to the user. The word “CAUTION” is used to indicate conditions or actions that may damage this instrument.WARNINGTo ensure safe operation and service of the tester, follow these instructions. Failure to observe these warnings can result in severe injury or death.WARNING• Before each use, verify meter operation by measuring a known voltage.• Never use the meter on a circuit with voltages that exceed the category based rating of this meter.• Do not use this meter during electrical storms or in wet weather.• Do not use the meter or test leads if they appear damaged.• Ensure meter leads are fully seated and keep fingers away from the metal probe contact when making measurements. Always grip the leads behind the finger guards molded into the probe.• Do not open the meter to replace batteries while the probes are connected.• To avoid false readings that can lead to electrical shock, replace batteries if a low battery indicator appears.• Unless measuring voltage, shut off and lockout power before measuring resistance.• Always adhere to national and local safety codes. Use proper personal protective equipment (PPE) to prevent shock and arc blast injury where hazardous live conductors are exposed.• Always turn off power to a circuit or assembly under test before cutting, unsoldering or breaking the current path. Even small amounts of current can be dangerous.• Always disconnect the live test lead before disconnecting the common test lead from the circuit.• In the event of electrical shock, ALWAYS bring the victim to the emergency room for evaluation, regardless of victim’s apparent recovery. Electrical shock can cause unstable heart rhythms that may need medical attention.• If any of the following occur during testing, turn off the power source to the circuit being tested: arching, flame, smoke, extreme heat, smell of burning materials or discoloration or melting of components.WARNINGHigher voltages require greater awareness of physical safety hazards. Before connecting the test leads; turn off power to the circuit under test, set meter to the desired function and range; connect the test leads to the meter first, then connect to the circuit under test.
