Key Features

• Dual-Trace Comparison Matrix: Allows technicians to display two separate waveforms side-by-side or superimposed on the screen, making it incredibly easy to cross-examine input versus output signals.

• Advanced Alternating (ALT) & Chopped (CHOP) Modes: Features automated display switching modes that maintain a stable, flicker-free visual trace whether analyzing high-frequency pulses or slow audio wave sweeps.

• High-Precision Add & Subtract Function: Equipped with a mathematical “ADD” mode that blends Channel 1 and Channel 2, allowing engineers to perform differential measurements and cancel out background line noise.

• X-Y Phase Alignment Mode: Supports professional X-Y coordinate operations, allowing the user to map Lissajous patterns for precise phase angle calculations and frequency ratio determination.

• Ruggedized Shielded Enclosure: Housed in an industrialized metal alloy frame designed to block external magnetic field distortions, paired with a heavy-duty carrying handle and a front tilt-stand for comfortable viewing.

Primary Applications

• Engineering and Physics Laboratories: Visualizing phase shifts, tracking transient response curves, and demonstrating complex alternating current circuit theories.

• Telecommunications and Signal Analysis: Testing modulator circuits, inspecting transceiver phase adjustments, and checking transmission line signal attenuation.

• Premium Audio and Audio Matrix Testing: Mapping phase tracking between left and right sound channels, measuring amplifier cross-talk, and locating harmonic distortion nodes.

• Industrial Quality Control & Troubleshooting: Diagnosing switching power supply frequencies, verifying clock generator pulses, and checking automated assembly control loops.
