OPERATIONAL DESCRIPTION The equipment under test (EUT) is a transmitter of 2.402-2.480GHz ATLANTIK speaker. A major technical description of EUT is described as following Product Designation Flower Shower LED Speaker Operation Frequency 工作频率 26MHz Maximum conducted Peak output power 最大传导峰值输出功率 3.06dBm Modulation 振幅调制 1M 2M 3M Number of channels 通道数 72 Hardware Version 硬件版本 VE Software Version 软件版本 S3319 Antenna Designation 天线名称 PCB Antenna Antenna Gain 天线增益 -0.58dBi Power Supply Normal Voltage: 正常电压 DC 3.7V Operation principle description: The 300mAh polymer battery provides operating voltage and current to the entire circuit. When the battery power is low, the battery can be charged through the charging column. The 26MHz crystal oscillator provides the main control chip with a normal operating frequency. The 36D main control chip receives the signal sent by the corresponding function button, and performs functions such as turning on and off, adjusting the upper and lower song and the volume, and at the same time lights up different LED instructions in different states. The signal is received through the carrier frequency of 26MHz , and the audio signal is decoded by the master to drive the speaker.
