Agilent 11970系列混合器数据手册说明书
Agilent 11970 Series Harmonic MixersData Sheet For use with the Agilent E4407B, 8560E/EC Series, 8566B,71000 Series, and PSA Series spectrum analyzers,plus the N9030A PXA signal analyzerExceptional performanceThe Agilent Technologies 11970 Series harmonic mixers are general purpose mixers employing a dual-diode design to achieve very flat frequency response and lowconversion loss. Each mixer is calibrated across its full band:11970K* 18 to 26.5 GHz 11970A 26.5 to 40 GHz11970Q 33 to 50 GHz 11970U 40 to 60 GHz11970V 50 to 75 GHz 11970W 75 to 110 GHzThis series of mixers has been designed for a local oscillator frequency of 3 to 6.1 GHz. Accurate absolute amplitude measurements can be made by using the mixer’s conversion loss calibration chart. The SWR of the waveguide input is typically 2.2:1 to further minimize measurement uncertainty. The combination of high gain-compression level and low conversion loss provides the maximum dynamic range for measuring input signals.* 11970K is excluded from PXA support18 to 110 GHz11970K*, 11970A, 11970Q, 11970U, 11970V, 11970W19812Easy to useThe excellent frequency response and low conversionloss are achieved without external dc bias or tuning stubs. Since bias and tuning stubs are not required, manualoperation is simplified, and the complexity of hardware and software for automatic systems is greatly reduced. The repeatability of amplitude measurements is also enhanced. The dual-diode design of the mixers further simplifiesmeasurements by suppressing the odd-order harmonics by more than 20 dB, which makes identification of the mixing products easier.RuggedThe rugged Agilent 11970 Series mixers willsurvive input levels up to 100 milliwatts (+20 dBm)with no damage to the mixer diodes. They will withstand shocks up to 30 G’s and the vibration required by MIL-STD 28800C, Type III, Class 3 tests.Figure 1. The 11970 Series mixers have separate LO input and IF output portsAgilent 8560E/EC Series spectrum analyzer Extended frequency 8560E/ECSeriesFrequency extension for the Agilent E4407B,8560E/EC Series, 8566B, and 71000 Series and PSA Series spectrum analyzersThe 11970 Series harmonic mixers are fully compatiblewith the Agilent E4407B, 8560E/EC Series, 8566B (requires a preamplifier), 71000, and PSA Series spectrum analyzers. Accurate frequency and amplitude measurements are made directly from the spectrum analyzer’s display after calibration using the mixer’s calibration chart.Frequency extension for the Agilent N9030A PXA Series signal analyzerThe 11970 Series harmonic mixers (11970K excluded) are also compatible with the N9030A PXA Series high-performance signal analyzer. The PXA offers optional external mixing (Option EXM), enabling it to work with the 11970 Series and other external mixers for frequency extension. An external diplexer is required because the PXA external mixing has a single SMA LO/IF port, whereas the 11970 Series mixers have separate LO and IF ports. Recommended diplexers can be purchased from Agilentas N9020A-E13, or from OML Inc. as DLP.313B.Spectrum analyzerExtended frequency PSA SeriesAgilent E4407B spectrum analyzer Extended frequency E4407B ESA-E SeriesAgilent N9030APXA Series signal analyzer Extended frequency PXA Seriesharmonic mixer3Input frequency, GHzNominal frequency response & conversion loss1826.533 40 50 60 75 110C o n v e r s i o n l o s s , d B50454035302520KAQUVWSpecificationsSpecifications describe the device’s warranted performance over the temperature range 0 to 55° C (except where noted).11970 Series tested with Agilent PSA spectrum analyzersAgilent model number Frequency range (GHz) LOharmonic number Maximum conversion loss (dB) Nominal spectrum analyzer noise (dBm)1 kHz BW Frequency response (dB) Nominal gain compression (dBm)11970K 18 to 26.56– 24 –105 ±1.9 –311970A 26.5 to 40 8– 26 –102 ±1.9 –511970Q 33 to 50 10– 28 –101 ±1.9 –711970U 40 to 60 10– 28 –101 ±1.9 –711970V 50 to 75 14– 40 –92 ±2.1 –311970W75 to 11018–46–85±3.0–1Nominal performance, as noted in the following tables, while not warranted, provides information useful in applying the device.1.

161科技资讯 S CI EN CE & T EC HNO LO GY I NF OR MA TI ON 工 程 管 理1 安全生产执行效果的概述安全生产执行效果是指以人为本,坚持“安全第一,预防为主,综合治理”的方针,贯彻安全生产战略意图,完成提高安全生产管理水平、预防和控制事故的发生、确保人民生命财产及健康的安全的实际操作能力。
安全生产执行效果是推动企业安全生产工作顺利进行的有力武器,是提高安全生产管理水平的关键因素。
执行效果是企业的核心竞争力,没有安全生产执行效果,安全生产管理水平只能处于停滞不前的状态,无法改变安全生产管理水平薄弱的现象。
企业领导虽然重视安全生产,在各种场合都强调要加强安全生产管理,确保安全生产,但是实际到项目部的管理上却是“安全说起来重要,做起来次要,忙起来不要”,不愿意对安全生产管理投入资金,各项安全生产制度没有得到落实。
项目部施工往往是将工作进度和成本控制放在第一位,而把安全、质量放在最后,这与我国安全生产方针是背道而驰的,导致安全工作没有得到落实,安全生产管理流于表面,究其根本原因就是缺乏有力的安全生产执行效果。
2 分析项目部安全生产制度执行效果不足的原因项目部是安全生产管理的责任主体,安全生产执行效果不容乐观。
由于项目部是在一定的时间内,完成一定的生产任务,项目部的领导层主要是以完成生产任务为主要目的,从而在一定的程度上忽略安全生产管理。
不学习安全生产法律法规、不掌握安全技术规程、不规范履行安全生产管理职责,对上级安全生产管理部门下发的安全生产管理制度,不认真学习领会,对安全生产检查总是在敷衍,导致项目部本身基本的安全生产管理模式改变,安全生产执行效果中断。
2.1项目部管理层存在问题(1)项目部在接到公司的某一项安全生产活动的指示后,不认真学习领会指示精神,不能真正理解执行该项活动的目的和意图,而是大笔一挥交到安质部门办理。
不能有效地将活动指示精神布置到管理层和执行层,造成安全生产规章制度在执行过程中打折扣。

美国药典 791 PH 中文翻译
<791>pH对于药典用途，pH定义为由合适的，正确标定的，使用对氢离子活度敏感的指示电极，玻璃电极，及适当的参比电极，具有重复pH值至0.02单位的电位计或酸度计(pH 计)给定的值。
仪器应能够指示通过电极对的电势，对于pH标定，通过操纵“标定”，“调零”，“不对称”或“校正”控制调节电路的电势，并应可以通过“温度”和“斜率”控制来控制每单位毫伏的变化改变pH读数。
除了在单个专论中有特殊说明的外，测量在25 ± 2℃下进行。
pH值由以下方程式定义：pH = pHs + (E – E S)/k其中E 和 E S分别是检测中原电池所包含溶液测定的电势，由pH表示，及合适的标定缓冲溶液，用pHs表示。
K值是每单位pH 值的改变所对应改变的电势，理论上在任何温度t下它都应为[0.05916 + 0.000198(t – 25℃)]伏。
需要强调的是pH定义，pH尺度和标准缓冲液的指定值都是为了确定一个实际的，可操作的操作系统，以便在实验室间进行结果对比。
因此测定的pH值与根据定义pH =–log a H+计算出的pH值并不精确符合。
只要被测溶液与标准缓冲液中的成分充分接近，测定的pH值就与理论pH值十分接近了。
尽管没有关于测量氢离子活度或浓度的系统适应性要求的制定，在水溶液中得到的值仍与相应的氢离子活度相近。
如果通过用标准缓冲液校正pH计，然后用该pH计来测量非水溶液或悬浮溶液的“pH”值，酸碱的电离常量，溶剂的介电常数，液接界电势（可能有近似1单位pH 的误差）和玻璃电极氢离子响应值都发生改变。
基于这些原因，性状为部分水溶液的溶液得到的pH值只是一个表观pH值。
pH计标定用的缓冲溶液标准缓冲溶液的制备描述如附表*所述。
必需纯度的缓冲盐可通过国家科学院（National Institute of Science and Technology）得到。
溶液应贮藏在带有密封装置的或有二氧化碳吸收管（苏打石灰）的硬质玻璃瓶或聚乙烯瓶中。
