200FPFiltered Tone ProbeDescriptionThe 200FP Filtered Tone Probe is designed to identify andtrace wires or cables within a group without need of removinginsulation. In addition, the 200FP has been specifically designed tofilter out all power-related noise to eliminate “Power Line Hum.”The unit is constructed of durable ABS plastic, and an optionalleather carrying case, 200C, is available.The 200FP is alsoavailable as part of the Model 801K kit.When the 200FP is ON but not detecting a signal, the signal LEDwill flash momentarily (every 4 seconds) as a visible ON indicatorand reminder. When a tone signal is detected by the probe, thesignal LED will serve as a signal strength indicator.The brighterthe LED, the stronger the tone signal detected.SafetySafety is essential in the use and maintenance of Tempo Toolsand equipment. This instruction manual and any markings on thetool provide information for avoiding hazards and unsafe practicesrelated to the use of this tool. Observe all of the safety informationprovided.Purpose of this ManualThis manual is intended to familiarize personnel with thesafe operation and maintenance procedures for the TempoCommunications 200FP Filtered Tone Probe. Please read thisentire manual before operating the tool, and keep this manualavailable to all personnel. Replacement manuals are availableupon request at no extra charge.Controls (See Figure 1)A long press of the main control button turns the unit OFF or ON,and the unit beeps to indicate the change. A lower pitch beepindicates that the unit is going OFF. An Auto-Off feature hasbeen incorporated to turn the 200FP OFF after 5 minutes to helppreserve battery life. When Auto-Off activates, a bee-bee-bee-beep sounds from the speaker to alert the user that the 200FP isnow OFF. When the battery voltage is low, the unit sounds threedescending tones when it is turned ON.Short presses of the main control button engage and disengagethe hum filter of the 200FP. The unit beeps to indicate the change– a single beep means it is entering the normal unfiltered mode, 52080289 REV01 © 2019 Tempo Communications Inc. 08/19Do not discard this product or throw away!For recycling information, go to .All specifications are nominal and may change as design improvementsoccur. Tempo Textron Inc. shall not be liable for damages resulting frommisapplication or misuse of its products.KEEP THIS MANUALmode the LED indicator operates in red color, and in filter mode the LED appears green.A volume control knob located on the right side of the 200FPallows the user to control the sensitivity and loudness of the probe output.OperationIdentification of wires and cables is accomplished by first connecting a tracing tone generator like the TempoCommunications 77HP , 77GX or AT8 to the wires being traced.In working cables that are terminated, connect one lead of the tone generator to a wire and the other test lead to earth or equipment ground. This allows localization of the cable and un-terminated cables, 1. To activate the 200FP , use a long press of the square main control button.Note: Changes in temperature and battery power can affect the frequency of tones produced by any given tone generator. Under certain conditions, a tone test set may produce frequencies that are similar to power line hum and cause them to be blocked by the 200FP’s filter mode.2. Prior to locating the tone at the far end of the cable or wire, confirm proper operation of the 200FP at the tone source. With the probe ON and in the filter mode (a short press of the control button and a green LED blink), listen for a solid single tone or a complete warble tone at the tone generator. If no tone or only “half ”of a warble tone is detected, use the 200FP in the “Normal” unfiltered setting or replace the battery in the tone generator.3. Once activated, the volume control can be adjusted to suit the environment. Loudness of the probe tone output can be increased to overcome noise (i.e., vehicular traffic, airplanes or machinery) or decreased to reduce interference or when working in noise sensitive areas.4. The 200FP is equipped with recessed ports for connecting a lineman’s butt set. Attaching the butt set automatically activates the probe when Talk mode is selected on the set.5. To activate the 200FP without depressing the main control button, silence the speaker, and use only the LED, attach a jumper between the two recessed tabs. This simulates connection of a butt set.6. Touch the tip of the 200FP to the insulation of each potential target conductor.7. Reception of tone will be loudest on the subject wire. (Reception of the tone may be improved by separating the wires from the group.)SpecificationsElectricalNominal Gain: 35 dBNominal Input Impedance: 100 MΩProbe Tip Resistance (minimum): 300 ΩBattery: One 9V alkalineNominal Battery Life: 50 hoursOvervoltage Protection: Cat I, 150V to GndPhysicalLength: 250 mm (9.85")Width: 32 mm (1.27")Depth: 35 mm (1.38")Weight: 142 g (5 oz)Operating/Storage ConditionsTemperature: 0 °C to 50 °C (32 °F to 122 °F)MaintenanceBattery Replacement1.

滤波器通用质量特性保障大纲
一、滤波器(filter)通用质量特性保障大纲概述
滤波器通用质量特性保障大纲旨在提供一个质量保证指南，用于评估和核实滤波器所使用的通用组件的质量特性。

质量特性以机械和电气性能的标准度量格式作为指标。

这规定了滤波器的机械和电气性能应满足的标准，特别是基于军事标准的电气质量，能够提供滤波器运行的安全操作保障，可靠的性能表现，抗电磁干扰性强等特点，降低过程变量的测量错误和故障几率，从而达到“高品质，性价比高”。

二、滤波器通用质量特性保障大纲内容
1、外壳特性：滤波器外壳由军标完成框结构组成，材料采用环保型电气材料，形式标准，外形整洁，无剂有缺陷，能够满足高低温、潮湿等变化的环境工况要求。

2、绝缘性：滤波器绝缘性良好，高电压持久抗绝缘的特性要符合军标要求，提高电气安
全性和可靠性。

3、电性能：滤波器电性能要满足信号传输特性及控制精度需求。

抗电磁干扰能力要符合JIS和军标规定，提高滤波器的安全性、精准性和性能可靠性。

4、机械性能：滤波器的机械性能要达到额定动态性能、轴向结构的强度、耐磨性、密封
性和外形尺寸等要求，滤波器运行时不会发生机械损坏以及表面磨损。

三、滤波器通用质量特性保障大纲的重要性
滤波器应用于许多场合，处理的都是电信号及信息，有时还会加上控制和查询操作，因此，质量控制对滤波器的性能和可靠性起到非常重要的作用。

滤波器通用质量特性保障大纲提供了一套系统的质量保证实施指南，以确保滤波器在运行中能够正常、安全、可靠地发挥
作用，为使用者提供便利和保障。

滤波器的主要参数（Definitions）：中心频率（Center Frequency）：滤波器通带的中心频率f0，一般取f0=（f1+f2）/2，f1、f2为带通或带阻滤波器左、右相对下降1dB或3dB边频点。

窄带滤波器常以插损最小点为中心频率计算通带带宽。

截止频率（Cutoff Frequency）：指低通滤波器的通带右边频点及高通滤波器的通带左边频点。

通常以1dB或3dB相对损耗点来标准定义。

相对损耗的参考基准为：低通以DC处插损为基准，高通则以未出现寄生阻带的足够高通带频率处插损为基准。

通带带宽（BWxdB）：指需要通过的频谱宽度，BWxdB=（f2-f1）。

f1、f2为以中心频率f0处插入损耗为基准，下降X（dB）处对应的左、右边频点。

通常用X=3、1、0.5 即BW3dB、BW1dB、BW0.5dB 表征滤波器通带带宽参数。

分数带宽（fractional bandwidth）=BW3dB/f0×100[%]，也常用来表征滤波器通带带宽。

插入损耗（Insertion Loss）：由于滤波器的引入对电路中原有信号带来的衰耗，以中心或截止频率处损耗表征，如要求全带内插损需强调。

纹波（Ripple）：指1dB或3dB带宽（截止频率）范围内，插损随频率在损耗均值曲线基础上波动的峰-峰值。

带内波动（Passband Riplpe）：通带内插入损耗随频率的变化量。

1dB带宽内的带内波动是1dB。

带内驻波比（VSWR）：衡量滤波器通带内信号是否良好匹配传输的一项重要指标。

理想匹配VSWR=1：1，失配时VSWR>1。

对于一个实际的滤波器而言，满足VSWR<1.5：1的带宽一般小于BW3dB，其占BW3dB的比例与滤波器阶数和插损相关。

回波损耗（Return Loss）：端口信号输入功率与反射功率之比的分贝（dB）数，也等于|20Log10ρ|，ρ为电压反射系数。

输入功率被端口全部吸收时回波损耗为无穷大。

滤波器的主要参数（Definitions）：欧阳家百（2021.03.07）中心频率（Center Frequency）：滤波器通带的频率f0，一般取f0=（f1+f2）/2，f1、f2为带通或带阻滤波器左、右相对下降1dB或3dB边频点。

窄带滤波器常以插损最小点为中心频率计算通带带宽。

截止频率（Cutoff Frequency）：指低通滤波器的通带右边频点及高通滤波器的通带左边频点。

通常以1dB或3dB相对损耗点来标准定义。

相对损耗的参考基准为：低通以DC处插损为基准，高通则以未出现寄生阻带的足够高通带频率处插损为基准。

通带带宽（BWxdB）：指需要通过的频谱宽度，BWxdB=（f2-f1）。

f1、f2为以中心频率f0处插入损耗为基准，下降X（dB）处对应的左、右边频点。

通常用X=3、1、0.5 即BW3dB、BW1dB、BW0.5dB 表征滤波器通带带宽参数。

分数带宽（fractional bandwidth）=BW3dB/f0×100[%]，也常用来表征滤波器通带带宽。

插入损耗（Insertion Loss）：由于滤波器的引入对电路中原有信号带来的衰耗，以中心或截止频率处损耗表征，如要求全带内插损需强调。

纹波（Ripple）：指1dB或3dB带宽（截止频率）范围内，插损随频率在损耗均值曲线基础上波动的峰-峰值。

带内波动（Passband Riplpe）：通带内插入损耗随频率的变化量。

1dB带宽内的带内波动是1dB。

带内驻波比（VSWR）：衡量滤波器通带内信号是否良好匹配传输的一项重要指标。

理想匹配VSWR=1：1，失配时VSWR<1。

对于一个实际的滤波器而言，满足VSWR<1 BWdBBWdBdiv>在入射波和反射波相位相同的地方，电压振幅相加为最大电压振幅Vmax ，形成波腹；在入射波和反射波相位相反的地方电压振幅相减为最小电压振幅Vmin ，形成波节。

其它各点的振幅值则介于波腹与波节之间。
