This device features two independent output channels, each capable of producing complex waveforms with full control over amplitude, frequency, phase, and duty cycle. The dual‑channel design allows simultaneous generation of multiple signals or the creation of differential pairs for high‑speed communication testing.

Channel Independence

• Independent waveform programming per channel.
• Separate amplitude ranges and offset controls.
• Simultaneous burst, sweep, or continuous operation modes.

Frequency Counter Capability

The built‑in 200 MHz frequency counter provides precise measurement of the output signals. This feature is essential for verifying modulation accuracy and ensuring compliance with stringent RF specifications.

Key Measurement Features

• High resolution counting up to 200 MHz.
• Real‑time display of frequency, period, and duty cycle.
• Data logging for post‑analysis.

Modulation Support

The PEAKTECH 4165 supports a wide array of modulation schemes, enabling comprehensive testing of communication systems:

• Amplitude Modulation (AM)
• Frequency Modulation (FM)
• Phase Modulation (PM)
• PWM (Pulse‑Width Modulation)
• FSK (Frequency Shift Keying)

Modulation Configuration

Users can set modulation parameters such as carrier frequency, deviation, and modulation index directly through the intuitive interface. The device automatically adjusts the waveform to match the desired modulation characteristics.

User Interface & Display

The color TFT screen offers a clear visual representation of waveforms, settings, and measurement data. Its high‑resolution display supports zooming, scrolling, and real‑time plotting, which simplifies waveform design and troubleshooting.

Interface Highlights

• Touch‑friendly navigation for quick parameter adjustments.
• Graphical representation of amplitude vs. time or frequency spectra.
• Customizable display panels for each channel.

Sweep and Burst Modes

The device includes versatile sweep and burst functionalities, allowing users to generate dynamic signals that change over time:

• Frequency sweep: Linear or logarithmic ramps across the full frequency range.
• Amplitude sweep: Gradual changes in signal level for stress testing.
• Burst mode: Short, repeated pulses with precise timing control.

Applications of Sweep/Burst Features

These modes are invaluable for:

• Testing receiver sensitivity across a spectrum.
• Evaluating filter responses to transient signals.
• Simulating real‑world communication scenarios such as packet bursts.

Waveform Generation Capabilities

The PEAKTECH 4165 can produce a wide variety of waveforms, including:

• Sine, square, triangle, and sawtooth.
• Custom user‑defined shapes via waveform memory.
• Composite signals combining multiple harmonics.

Arbitrary Waveform Storage

Users can upload custom waveforms from a PC or create them directly on the device. The internal memory holds several pre‑programmed patterns, which can be recalled instantly for rapid testing cycles.

Precision and Stability

The generator’s 1 µHz resolution ensures that even the smallest frequency adjustments are achievable, providing exceptional stability for low‑frequency applications such as sensor calibration or precision timing tests.

Temperature Compensation

Built‑in temperature monitoring and compensation algorithms maintain waveform integrity across varying environmental conditions.

Connectivity & Integration

The device offers multiple interfaces to integrate seamlessly into test setups:

• USB for PC control and firmware updates.
• RS‑232/RS‑485 for legacy equipment communication.
• GPIB (IEEE‑488) for automated test systems.

Software Support

A comprehensive software suite allows users to script complex sequences, automate measurements, and export data in standard formats such as CSV or XML.

Typical Use Cases

• RF Communication Testing: Generating carrier signals with AM/FM/PM modulation for base‑station evaluation.
• Embedded Systems Development: Providing precise clock and reference signals during firmware debugging.
• Signal Integrity Analysis: Using burst modes to assess interconnect performance under transient conditions.
• Educational Laboratories: Demonstrating waveform synthesis, modulation techniques, and frequency measurement concepts.
