QLS3600S series instrument utilizes large-scale FPGA integrated circuit
and 32-bit high-speed ARM microprocessor. the internal circuit adopts surfacemount technology, which greatly enhances the instrument"s interferenceresistance and service life. The display interface uses a 2.4-inch TFT LCDscreen with 320*240 high resolution. It can display all channel parameters andprompt current key functions, efficiently utilizing key resources and avoidingfrequent key operations, significantly enhancing operability. This instrumenthas significant advantages in terms of signal generation, waveform scanning,parameter measurement, and usage. It is an ideal test and measurement devicefor electronic engineers, electronic laboratories, production lines, and educationalresearch.
