背景技术Background technique
随着物联网行业的发展以及RF射频、wifi、BT(蓝牙)、ZigBee、NFC(近距离接触)等无线技术日益成熟，ZigBee信号收发设备等无线收发设备的生产量将逐渐加大。而由于ZigBee信号收发设备等产品生产选择器件类型、温度变化、器件组装等因素的影响，即使是基于同样的平台同样的设计，也可能出现不同性能的产品。因此，ZigBee测试仪等无线信号测试仪在这些无线收发设备的研发、生产、测试过程中被广泛使用，用于测量和监控这些无线收发设备的一些无线通信性能指标，保证其通信的性能指标符合标准要求，如智能家居应用ZigBee技术的无线传输性能指标测试，所涉及测试的无线传输指标主要有以下几个：输出功率(OutputPower)，频率误差(FerqErr)，误差向量幅度(EVM)，丢包率(PER)，接收信号强度(RSSI)等。无线信号测试仪通常包含有信号发射器和信号接收器，发射器发射出用于无线收发设备的测试所需要的无线信号，接收器用于测量所述无线收发设备接收所述无线信号后解码发射的无线信号的性能指标，因此，无线信号测试仪的自身输出信号的频率、功率、EVM是否准确可靠以及对接收信号的功率以及EVM等的测量结果是否准确可靠，对于无线收发设备的性能测试将显得非常重要。到目前为止，国家未颁布无线信号测试仪校准规范或检定规程，而现有的操作人员在使用无线信号测试仪也未考虑到无线信号测试仪的校准与否对测量结果带来的影响，从而造成测量结果不准确，或者同样的产品测量结果不一致，而且测量效率低。With the development of the Internet of Things industry and the increasing maturity of wireless technologies such as RF radio frequency, wifi, BT (Bluetooth), ZigBee, and NFC (near-field contact), the production of wireless transceiver equipment such as ZigBee signal transceiver equipment will gradually increase. However, due to the influence of factors such as the selection of device types, temperature changes, and device assembly for the production of ZigBee signal transceiver equipment and other products, products with different performances may appear even if they are based on the same platform and the same design. Therefore, wireless signal testers such as ZigBee testers are widely used in the research and development, production and testing of these wireless transceiver devices to measure and monitor some wireless communication performance indicators of these wireless transceiver devices to ensure that their communication performance indicators meet Standard requirements, such as the wireless transmission performance index test of smart home application ZigBee technology, the wireless transmission indicators involved in the test mainly include the following: output power (OutputPower), frequency error (FerqErr), error vector magnitude (EVM), packet loss rate (PER), received signal strength (RSSI), etc. A wireless signal tester usually includes a signal transmitter and a signal receiver. The transmitter emits the wireless signal required for the test of the wireless transceiver device, and the receiver is used to measure the decoding and emission of the wireless transceiver device after receiving the wireless signal. The performance index of the wireless signal, therefore, whether the frequency, power, and EVM of the wireless signal tester's own output signal are accurate and reliable, and whether the measurement results of the power of the received signal and EVM are accurate and reliable, will be important for the performance test of the wireless transceiver equipment. Very important. So far, the country has not promulgated calibration specifications or verification procedures for wireless signal testers, and the existing operators have not considered the impact of the calibration of the wireless signal tester on the measurement results when using the wireless signal tester, thus The measurement results are inaccurate, or the measurement results of the same product are inconsistent, and the measurement efficiency is low.
