• Waveform Stability: Designed for high signal integrity—sine wave distortion is under 1% for 10 Hz–100 kHz, ensuring clean, reliable output across most practical ranges.
  

Rich Array of Waveforms & Control Mechanisms

• Waveform Types: Generates a comprehensive selection, including sine, square, triangle, positive/negative sawtooth, and positive/negative pulse waves—ideal for simulation, design, and testing tasks.
  

• Duty/Symmetry Control: Adjust symmetry from 90:10 to 10:90, letting you craft nuanced ramp or pulse shapes with precision.
  

• DC Offset (Bias): Continuously adjustable between 0 to ±10 V, so you can superimpose DC levels onto waveforms—a critical feature for offset-dependent circuit testing.
  

High-Speed Signal Characteristics

• Square-Wave Sharpness:

  • Up to 2 MHz: Rise time < 100 ns

  • Up to 5 MHz / 10 MHz / 15 MHz (other variants): Rise time < 35 ns
    

Output Quality & Signal Integrity

• Amplitude: At load, delivers at least 20 V peak-to-peak, ensuring sufficient drive for various testing needs.

• Impedance: Built-in 50 Ω ±10%, aligning with industry-standard measurement systems and minimizing reflection errors.
  

• Attenuation Options: Integrated 20 dB and 40 dB steps provide versatile amplitude scaling ranging from tens of millivolts to tens of volts.
  

Enhanced Control & External Modulation

• Voltage-Controlled Frequency (VCF):

  • Input range: –5 V to 0 V ±10%

  • Frequency control via external voltage—adjustable and programmable frequency modulation ideal for complex signal synthesis.
    

• TTL / CMOS Synchronization Output: Provides a clean digital output clock from the generated waveform, with typical levels ≤0.4 V (low) and ≥3.5 V (high), with ≤100 ns rise time. Ideal for precise timing and synchronization.

Onboard Frequency Meter & External Measurement

• Internal Frequency Counter:

  • Measures internally generated or external input frequencies from 1 Hz to 20 MHz with high precision (≤0.003% + 1 digit).

  • Input is supported with ≥1 MΩ / 20 pF impedance, sensitivity: 100 mV RMS, and tolerates up to 150 V AC+DC with an external attenuator.

This dual generator-counter design is powerful for both generation and measurement tasks without requiring additional instruments.

Design Excellence & User-Oriented Construction

• Robust Build: The unit features an all-metal chassis, fitted with elegant plastic panels—designed to withstand frequent use and mechanical stresses.
