FG-100 DDS function signal generator - Small and portable: the FG-100 is compact, fully functional and easy to use. It is lightweight and can operate from an adapter or a lithium battery for on-the-go use. - Versatile applications: ideal for use with an oscilloscope for circuit testing and debugging. It can also test and measure frequency characteristics and pulse responses from audio amplifiers, and its accuracy and frequency stability support calibrating the scan time factor. - Multiple waveforms: offers sine wave, rectangular shaft, triangular shaft, forward sawtooth shaft and reverse sawtooth shaft to meet different test requirements. - Wide and precise frequency range: sine wave 1 Hz to 500 kHz, other waveforms up to 20 kHz, with a frequency resolution of 1 Hz for precise signal generation. - Key attributes: compact size, functional versatility, and stable performance suitable for laboratory and field use. - Use scenarios: 1) Bench testing a circuit with an oscilloscope to verify timing and waveform integrity. 2) Evaluating an audio amplifier’s frequency response and pulse behavior. 3) Field calibration of scan time factors or timing-sensitive tests using portable power.
