Key Features:
Waveform Generation: Both models generate sine, square, and triangle/ramp waveforms with high precision.
Display: Equipped with a bright color LCD display featuring a waveform preview for easy setup and monitoring.
Sweep Modes: Support for linear and logarithmic sweep, ideal for frequency response analysis.
Modulation: Built-in AM/FM modulation capabilities for more advanced waveform generation tasks.
Duty Cycle Control: Adjustable duty cycle for custom waveform configurations.
Variable DC Offset: A continuously variable DC offset allows for precise signal biasing, with independent amplifiers that enable large offsets even with small signal amplitudes (e.g., 10 mV).
Triggering: Both models offer internal/external triggering, enhancing their functionality for gated and burst modes (4040B only).
Built-in Counter: Provides accurate frequency measurement directly from the instrument.
USB Interface: Includes a USB port with SCPI-compliant commands for remote control and data logging.
Protection: Short circuit and overvoltage protection ensure safe operation under various conditions.
