Outputs sine, square, triangle, and pulse wave, Maximum output power 810Wp, Bandwidth (-3dB) DC~30kHz
Driving a piezoelectric actuator, an ultrasonic transducer, or another power-hungry load with a precisely shaped waveform needs more than a standard signal generator can deliver — a conventional function generator produces accurate waveforms but at signal-level power, leaving a separate amplification stage needed before the waveform can actually drive the load. Aigtek's ATG-300 Series combines both functions directly, generating sine, square, triangle, and pulse waveforms at up to 810Wp of output power.
Bandwidth to 30kHz (-3dB) covers a solid range of low-to-mid-frequency drive applications, and the ability to select internal or external input signal gives flexibility in how the waveform is generated — internally programmed for standalone use, or externally driven when the waveform needs to originate from another instrument or control system while the ATG-300 handles the power amplification.
Combining waveform generation and power delivery in a single instrument removes a separate amplifier stage from the test setup, simplifying the signal chain for applications like MEMS testing, piezoelectric actuator drive, and other power-type loads that need an accurately shaped waveform at real drive power rather than signal-level output.

⬇ Download Datasheet (PDF) Enquire About ATG-309 →A separate function generator plus power amplifier setup requires matching the two instruments' bandwidth and signal characteristics, adds cabling and potential signal integrity issues between them, and takes up more bench space. A combined instrument like the ATG-300 removes that integration step, delivering the shaped power waveform directly from one unit.
External input is useful when the waveform itself needs to come from another source — a function generator producing a more complex or application-specific waveform shape, or a control system driving the signal dynamically — with the ATG-300 then providing the power amplification stage rather than generating the waveform itself.
Power-type loads that need real drive power rather than signal-level output — applications like piezoelectric actuators, ultrasonic transducers, and similar power-hungry devices where the load itself demands watts of drive power delivered in an accurately shaped waveform.
