Key benefits - Reliable frequency modulation for enthusiasts and professionals in projects or experiments. - When the frequency is high, output deviation is less than 1 percent between the input and the actual output. - The sound output from speakers is determined by the frequency; at low frequencies the human ear cannot hear them, but when the frequency reaches the audible range a tone is produced if speakers are connected. - Type-C power interface for easy connection and stable power delivery; plug-and-play for quick setup. - Suitable for home studios, research laboratories, or any environment where stable frequency generation matters. What you get and how it helps - Function: a reliable source of frequency modulation with measurements that stay within a tight tolerance at higher frequencies. - Compatibility: Type-C power interface and straightforward plug-and-play operation. - Performance: audible tone emerges when the frequency falls into the human hearing range, enabling quick checks and verifications. - Practicality: designed for environments where stable frequency generation is important, from creative studios to scientific labs. 2-3 practical use scenarios - Home studio calibration: generate precise test tones to evaluate and calibrate monitors, microphones, and audio interfaces, ensuring accurate tonal response. - Research and experimentation: provide a stable frequency source for experiments that require consistent modulation or timing references. - Equipment testing and service: plug in speakers and use audible tones to verify operation as the frequency moves into the hearing range, aiding quick diagnostics. Note: This product maintains the original emphasis on frequency modulation reliability, high-frequency accuracy, audible feedback via speakers, Type-C power compatibility, and plug-and-play usability.
