HE700GEN200C具备触控功能的面板在此必须强调一个观念，那就是载台噪声的存在是不可避免的，我们不可能将噪声降到零值，因为模块必须透过系统供电，而模块所放置的位置也会影响到邻近其它模块与接口，其中势必会有噪声的产生。不过载台噪声的存在虽然不可避免，却可以设法让其干扰降到最低、而不致影响通讯表现的程度，这也就是为什么我们要去量测噪声、找出干扰源的原因。

然而，要量测出载台噪声干扰并非难事，但若要验证载台噪声的来源有哪些、以及个别来源造成的干扰程度，则需要非常复杂与细致的量测方法，而这绝对是开发者的一大挑战。光是控制变因并对可能造成干扰的组件进行交叉量测，彼此间便可以产生上千种组合，像是不同的通讯频道间、Bluetooth与Wi-Fi、Wi-Fi与3G、3G与GPS等等，都可能因为讯号共存(Co-existence)、串音(Crosstalk)等状况造成讯号损耗。如何透过正确的量测顺序与手法、并将其间耗时的交叉量测加以自动化，以有效判断主要噪声源，便是其中的学问所在。

HE700GEN200降低噪声的首要重点:制定合理的噪声预算(Noise Budget)以进行调变。

热能传导模块有很多种，比如：

硅酸铝纤维模块，是一种含锆型纤维模块保温隔热材料，其热传导率低，防火性能好。电地暖模块，是一种用于农村煤改电的电采暖模块，其热传导快。流体循环热传导模块，是一种用于工业气体加热、油泵加热、不锈钢稀土厚膜速热板加热的热传导模块，其加热功率高、使用寿命长。

HE700GEN200热传感器的工作原理基于热敏效应和温度与电阻之间的关系。热传感器通常由一个热敏元件和一个电路组成。热敏元件是一种能够根据温度变化而改变电阻值的材料，常用的材料有铂、镍、铜等。当热敏元件加热或冷却时，其电阻值会发生变化，从而改变电路中的电流或电压。

HE700GEN200C panel with touch function must emphasize a concept here, that is, the presence of platform noise is inevitable, we can not reduce the noise to zero, because the module must be powered through the system, and the location of the module will also affect the neighboring other modules and interfaces, which is bound to have noise generation. However, although the existence of platform noise is inevitable, it can be managed to minimize its interference without affecting the degree of communication performance, which is why we have to measure the noise and find the source of interference.

However, it is not difficult to measure platform noise interference, but verifying the sources of platform noise and the level of interference caused by individual sources requires very complex and detailed measurement methods, which is definitely a challenge for developers. Just controlling the variables and cross-measuring the components that may cause interference can create thousands of combinations between each other, such as between different communication channels, Bluetooth and Wi-Fi, Wi-Fi and 3G, 3G and GPS, and so on. Signal loss can be caused by conditions such as Co-existence and Crosstalk. How to effectively determine the main noise sources through the correct sequence and method of measurement and the automation of time-consuming cross-measurements is the learning.

The primary focus of HE700GEN200 Noise reduction is to develop a reasonable Noise Budget for modulation.

There are many types of heat transfer modules, such as:

Aluminum silicate fiber module is a zirconium fiber module thermal insulation material, which has low thermal conductivity and good fire resistance. The electric floor heating module is a kind of electric heating module for rural coal to electricity, and its heat conduction is fast. Fluid circulation heat conduction module is a heat conduction module used for industrial gas heating, oil pump heating, stainless steel rare earth thick film fast hot plate heating, with high heating power and long service life.

The working principle of the HE700GEN200 thermal sensor is based on the thermal effect and the relationship between temperature and resistance. A thermal sensor usually consists of a thermal element and a circuit. The thermal element is a material that can change the resistance value according to the temperature change, and the commonly used materials are platinum, nickel, copper and so on. When a thermistor is heated or cooled, its resistance value changes, which changes the current or voltage in the circuit.
