Low Frequency Audio Signal Generator Signal Source 10Hz-1MHz Electronic Measureme Features: Made of high-quality materials, it is durable, wear-resistant and can be used for a long time. Reliable circuitry guarantees a high degree of stability and accuracy. The signal generator has the characteristics of a sine wave and an effective frequency response. The frequency range is selectable from 10Hz to 1MHz and is calibrated on one dial in five ranges. The vertical panel integration ensures the ease of use of the device and makes the operation simpler and more convenient. It is a tool for electrical engineering, laboratories, production lines, teaching and scientific research, and can also be used as a support module for industrial equipment.
