1Hz-500kHz DDS Functional Signal Generator, Portable Frequency Generator, Audio Signal Generator, Sine/Triangle/Square/Sawtooth Waveforms, FG-100

PARAMETERS: - Size: 125 × 80 × 32 mm/4.92×3.15×1.26in - Weight: ≈ 0.15 kg/0.33lbs (with accessories) - Sine: 1 Hz – 500 kHz (flat amplitude ≤ 200 kHz) - Other waves: 1 Hz – 20 kHz - Resolution: 1 Hz - Waveforms:- Sine, square, triangle, forward sawtooth, reverse sawtooth, noise, ECG - Signal Quality: Sine THD: <1 % (<1 kHz), <0.5 % (≥ 1 kHz) Output - Amplitude: max ±10 V p-p into 50 Ω - DC offset: ±10 V (can be disabled) - Output impedance: 50 Ω - Filter: switchable - Power Supply: 3.5 – 10 V DC - Memory: Settings saved automatically after adjustment PACKAGE 1* Frequency Generator 1* USB Cable APPLCATION: Bench & Field Testing -Inject precision sine/square into amps, filters, op-amp stages—spot gain, phase, clipping. -Quick frequency-response sweep of audio gear; watch amplitude flatness on scope. -Impulse-response check: drive speaker or amp with narrow square edge, view ringing/decay. Oscilloscope Calibration & Maintenance -Calibrate horizontal sweep: lock scope time-base to generator’s crystal-locked 1 kHz – 500 kHz square. -Probe compensation: use fast square to trim 10× probe capacitors for perfect flat tops. -Attenuator test: verify scope Volts/div accuracy with known ±10 V p-p levels. Servicing & Alignment -Inject marker tones into radios, servos, sensors—listen/watch for correct response. -Align active crossovers, equalizers, tone stacks with repeatable sine steps. -Noise source for quick SNR, gain-bandwidth checks. On-the-go Debugging -Pocket tool for field repairs: confirm clock crystals, drive missing signals, test cable continuity with square wave TDR trick.
