Agilent N432A Thermistor Power Meter 数据手册说明书
Agilent N432AThermistor Power MeterData SheetAgilent’s only power meter that supports thermistor mount with useful enhancements for metrology and calibration lab environments.Why Agilent’s Power Meters and Sensors?Reliable, high-performing solutionsEvery power meter and sensor from Agilent consistently delivers great results.A sure investment for many years to comeCode-compatibility between power meters reduces the need for re-coding. Notonly that, all Agilent power meters are backward-compatible with most legacypower sensors.One specific application: One right solutionAgilent offers a wide selection of power meters and sensors for practicallyall application needs—wireless communications, radar pulse measurements,component test, and more.Global network supportNo matter where you are, Agilent is committed to giving you the 24-hoursupport you need regarding our products, applications, or services.Agilent’s power meters have long beenrecognized as the industry standard forRF and microwave power measurements.We Listened to the Industry, Then Delivered a Better and Easier Replacement Solution for the Legacy 432A Analog Power MeterAs today’s power measurements become more complex, it is increas-ingly difficult to make reliable, accu-rate power measurements. For more than 40 years, you’ve depended on Agilent’s 432A analog power meter, used with temperature compensated thermistor sensors to provide high accuracy over a wide temperaturerange. LXI Class-C compliant N432AThe N432A is a single-channel, aver-age RF power measurement meter that supports thermistor sensors. The N432A has the capability to measure and display average power, RF bridge voltages (V RF0 and V RF1), compensation bridge voltages (V COMP0 and V COMP1), V 0, and V 1. It is also provided with a set of features such as zeroing and a built-in self-test.Developed using LXI technology, the N432A is an LXI Class-C compli-ant instrument.1 The N432A basic configuration consists of two key sections: bridge and meter logic. When a compatible thermistor sensor is connected to the N432A, the RF and compensation bridge circuits are formed in the bridge section. V RF , which is the voltage at the top of the RF bridge, is responsive to both input RF power and ambient temperature changes. On the other hand, V COMP , which is the voltage at the top of the compensation bridge, is responsive only to ambient temperature changes. The V RF and V COMP values are used in calculating the RF power. Meanwhile, the meter logic section processes V RF and V COMP to produce a meter current proportional to RF power.In general, the N432A is an easy-to-use instrument, especially with the availability of an integrated Web browser that provides a con-venient way to view and modify the instrument network configuration. Besides the LAN interface, the N432A also supports industry standard GPIB and USB interfaces for measurement automation.Today, the Agilent N432A digital thermistor power meter, loaded with enhancements, including a color digital display, and intuitive front panel interface will continue support your measurement needs with greater capability and expanded functionality. Best of all, you can get these extras at just a fraction of the price of the legacy 432A.1. LXI, an acronym for LAN eXtension for Instrumentation, is an instrument standard for devices that use the Ethernet (LAN) as their primarycommunication interface.High accuracy—no thermoelectric errorThe high accuracy ± (0.1% of reading + 0.5 μW) over a wide temperature range featured in the legacy 432A power meter is also included in the N432A, making it excellent for 1 mW transfer calibration (with 478A-H75/ H76*). Accuracy can be maintained on even the most sensitive range as the error due to thermoelectric effect is reduced to a negligible level.* 478-H75/H76 has a maximum SWR of1.05 at 50 MHz Sensor compatibilityThe N432A is compatible with the Agilent 478A and 8478B thermistor sensors. The following table lists the frequency range and operating resistance for these two sensors:478A0.01 to 10200478A Option H630.000001 to 1200478A Option H750.001 to 1200478A Option H760.001 to 12008478B0.01 to 18200For further information on the thermistor sensors, refer to the respective manuals.Take a Closer Look N432A front panel N432A back panelHigh-resolution color LCD display for easy viewing of test results Display key allows selection of the display format for the active window (single/split screen)Display key allows selection of the display mode (windowed, expanded, or full-screen) of numeric measurements Hard keys provide quick access to the most frequently used functions, such as System, Trigger, and Acquisition, etc.Channel sensor connectorArrow keys enable navigation of parameter entry screens, values selection, and entering of text Soft keys provide menu selection Numeric keypad for easy entry of numeric values Power reference of 1 mW (0 dBm)Ground connectorDC recorder outputs (DC voltage corresponds to the power level of the channel input)V RF and V COMP output terminals for calibrating the N432A and for precision power measurements Line power accepts voltage with automatic range selectionGo beyond GPRB with USB and LAN/LXI-C interfaceSpecifications and CharacteristicsSpecifications describe the instrument’s warranted performance and apply after a 30 minute warm-up.These specifications are valid over its operating/environmental range unless otherwise stated and after performing a zero and calibration procedure.Supplemental characteristics (shown in italics) are intended to provide additional information, useful in applying the instru-ment by giving typical (expected), but not warranted performance parameters.

2.5.1
电表的测量系统采用模拟电流值I1、I2、I3和模拟电压值U1, U2, U3作为输入信号。
2.5.2
电压输入
高阻抗分压器把施加在电表上的电压U1、U2、U3（57.7伏至132.8伏）成比例地降低到几毫伏（UU），进行进一步处理。
电流输入
同样，补偿电流互感器也降低施加在电表上的输入电流I1、I2、I3（0 A至2 A或0 A至7.5 A）。这些电流互感器的次级电流提高负载电阻器的电压。上述电压值与输入电流成比例，也是几毫伏（UI）。
如果电表遭受到流动的水或高压装置的侵害，如冲洗等，电表可能会损坏。可以用湿布清洁电表。
更换电池
警告
换上了错误型号或额定电压的电池，可能会损坏电表。
只允许把电池更换为额定电压为6伏并与原电池（型号：CR-P2）结构相同的锂电池。
如果电表与供电网长时间断开，备用功率会耗尽。当备用功率耗尽时更换电池，可能会产生无效的时间/日期信息，但不会产生相应的错误信息。
可以更改电流互感器的负载电阻器，使电表量程与所需的电流范围（1安或5安）相匹配。
2.5.3
使用模数转换器把模拟输入信号UU和UI转换为数字值，并使用各种过滤器过滤。
接着，就可以获得所有三相的电压（U）和电流（I）的数字瞬间值，这些值用于信号处理器生成数字原始值。
2.5.4
每隔0.2秒，信号处理器计算一次有功电量、无功电量和视在功率以及各种瞬时量，如相电压和相电流等。一般说来，ZMQ的测量系统和ZCQ产生单相数据，而ZFQ提供其两个测量元件相应的数据。
这些值是经过校验的原始数据，它们存储在信号处理器的输出缓冲器中，通过一个SPI接口把它们从输出缓冲器传送到微处理器中进一步运算。

图中CPU用于分时计费和处理各种输入输出数据，通过串行接口将专用电能芯片的数据读出，并根据预先设定的时段完成分时电能计量和最大需量计量功能，根据需要显示各项数据、通过红外或485接口进行通讯传输，并完成运行参数的监测，记录存储各种数据。
二、外形说明及安装
2.1
图2三相费控智能电能表外形图说明
翻开透明翻盖，右边有一块小盖板，打开小盖板可见一个电池槽，电池槽中安装有两节3V锂电池，供停电唤醒时使用(电表内部已焊有一节3.6V时钟电池用于维持内部数据不变及时钟运行)。安装时注意电池的正、负极方向。小盖板下方有一个按键为编程按键。
电流标识，分别代表Ia、Ib、Ic，功率反向时显示“-”号。失流时闪烁显示；当某相断流时该相电流标识消失(包括“-”号)。注：在三相三线表中，无B相电流。
