DDS Function Signal Generator Counter Signal Source Frequency Meter Pulse Generator Synthesizer QLS2800S 2MHz / 5MHz Description: brand new,high quality The internal circuit adopts surface mount technology, which greatly improves the anti-interference and service life of the instrument. The display interface adopts a 2.4-inch TFT liquid crystal display with 320*240 high resolution, which can display all the parameters of the channel and prompt the current button functions, effectively utilize the button resources, and avoid frequent user button operations, greatly enhancing the display interface. Operability. It is an for ideal test and measurement equipment for electronic engineers, electronic laboratories, production lines and teaching and research. Features: 1.Direct digital synthesis (DDS) technology, FPGA design, ultra-low power consumption; 2.a single DC5V power adapter power supply, easy to carry; 3.using 2.4-inch TFT true color LCD screen, with variable function buttons and rotary encoder, greatly enhance the ease of use of the machine; 4.Basic function waveforms such as sine wave, for triangle wave, square wave, sawtooth wave, and pulse wave with adjustable duty cycle; 5.the output signal frequency can be as small as 0.01 Hz; 6.There are 10 sets of parameter storage bits of M0~M9, and the data of M0 is automatically called up when booting; 7.The waveform frequency resolution is at least 0.01 Hz, and the amplitude resolution is at least 10 mV; 8.It has two trigger modes: manual trigger and external trigger. It can make the machine output any pulse train from 1 to 999999. 9.the pulse wave duty cycle adjustment is accurate to 0.5%; 11.Frequency scanning with an end point; 12.with frequency measurement, counting function; 13.All parameters can be calibrated by internal procedures; 14.powerful communication functions, making open communication protocol, making secondary development very simple; 15.After connecting with the PC, the PC can be used to control the instrument; 16.The operation interface can be switched between Chinese and English, and the scope and scope are wider; Function display: (1) Wave output function: output frequency 100K, peak-to-peak value 10V, sine wave signal with zero offset.
