5-1. 5-1。 BNC Cable Considerations BNC電纜注意事項(xiàng)
Accuracy of radio frequency measurements can be affected by connections between signal source and counter. 無(wú)線(xiàn)電頻率測(cè)量的精確度可以影響信號(hào)源和柜臺(tái)之間的連接。 Main considerations are standing waves and shunt cable capacitance 主要考慮的是駐波和分流電纜電容
Standing wave is usually present due to reflections when a transmission line is not terminated in its characteristic impedance. 駐波通常是目前由于時(shí)不終止其特性阻抗傳輸線(xiàn)的反射。 Theses standing waves may cause damage to the signal source or produce inaccurate measurements, and their effects increase as cable length reaches one-fourth of the wavelength for the frequency being measure. 論文駐波可能造成損害的信號(hào)源或產(chǎn)生不準(zhǔn)確的測(cè)量,并增加他們的影響,電纜長(zhǎng)度達(dá)到四分之一波長(zhǎng)頻率的措施。 Standing wave can be minimized by keeping cable lengths short, and more important, providing a proper termination 駐波可以盡量減少電纜長(zhǎng)度短,更重要的,提供適當(dāng)?shù)慕K止
The cable's characteristic impedance and the terminating impedance should match the source impedance. 電纜的特性阻抗和終端阻抗與源阻抗相匹配。 For example, for a source impedance of 50Ω, use 50Ω coaxial cable terminated with a 50Ω resistive load 例如,對(duì)于一個(gè)50Ω的源阻抗,使用終止與50Ω電阻負(fù)載50Ω同軸電纜
5-2. 5-2。 Use of attenuator probes 使用衰減器探頭
Input A resistance (1MΩ) and input capacitance (<40pF) are independent of the ATT switch. 電阻(1MΩ)輸入A和輸入電容(<40pF)是獨(dú)立的ATT開(kāi)關(guān)。 To decrease loading, a high impedance oscilloscope probe such as the following may be used with input A. Use the probe in the X10 position whenever possible for less circuit loading 為了減少負(fù)荷,如下面的一個(gè)高阻抗的示波器探頭可用于輸入A.使用X10的位置盡可能少的電路負(fù)載探頭
Note: 注意:
Do not use a 10:1 probe with the input C, the probe is designed for 10:1 attenuator with a counter input resistance of 1MΩ. 不要使用與輸入C 10:1的探頭,探頭是專(zhuān)為10:1衰減器與計(jì)數(shù)器輸入一個(gè)1MΩ電阻。 The 50Ω termination of the input C would result in unacceptable high attenuator. 50Ω終端輸入C會(huì)導(dǎo)致不可接受的高衰減。
5-3. 5-3。 Line frequency measurements 線(xiàn)頻率測(cè)量
Use of the attenuator, low pass filter, and /or X10 probe is advisable when measuring line frequency because the high amplitude signal and noise can cause wrong counting. 使用衰減器,低通濾波器,和/或X10的探頭是測(cè)量線(xiàn)路頻率時(shí)宜,因?yàn)楦哒穹盘?hào)和噪聲可能會(huì)導(dǎo)致錯(cuò)誤計(jì)數(shù)。
Warning 警告
Use caution in measuring the line frequency of an AC outlet. 測(cè)量線(xiàn)頻率的交流電源插座在使用謹(jǐn)慎。 Using the probe tip only, measure both sides of the line. 只使用探針尖,測(cè)量線(xiàn)兩側(cè)。 The ground side will give zero reading and the hot side will provide the desired measurement. 地面方將給予零讀數(shù)和熱方將提供所需的測(cè)量。 Do not use the “GROUND” lead of the probe. 不要使用“地面”探頭的鉛。 Remember that the chassis of the counter and the “GROUND” lead of the probe are already at earth ground (via the 3-wire power cord of the instrument). 請(qǐng)記住,計(jì)數(shù)器和探頭的“地面”鉛底盤(pán)是在已接地(通過(guò)儀器的3線(xiàn)電源線(xiàn))。 Touching the “GROUND” lead to the “HOT” side of the line would place a direct short on the power line through the probe cable, resulting in possible injury and damage to the probe cable. 接觸的“地面”導(dǎo)致的“熱”線(xiàn)一側(cè),將放置在電源線(xiàn)通過(guò)探頭電纜直接短路,導(dǎo)致在可能的傷害和損壞的探頭電纜。
