Dual-Channel Signal Generator TKXEC DC 5-24V 1Hz‑150kHz Phase Control

Description

Product Overview

The TKXEC Dual‑Channel Signal Generator is engineered for precision and flexibility in electronic testing and development. It operates on a broad DC input range of 5 to 24 V, allowing it to be powered from a variety of sources, from bench supplies to battery packs. The frequency capability stretches from a low 1 Hz up to 150 kHz, covering audio, control, and high‑speed signal applications. Each channel can be configured independently or synchronized, providing a phase adjustment range of 0° to 360° with 1° resolution, which is essential for timing‑critical experiments. Output current is limited to 0.2 A, sufficient for driving small loads, motor drivers, and PWM circuits. The device features a clear dual‑screen LCD that displays voltage, frequency, duty cycle, and phase settings in real time, reducing setup time and minimizing errors.

Usage

Designed for engineers, hobbyists, and educators, this generator fits seamlessly into laboratory benches, prototype rigs, and field testing kits. It excels in motor driver development, where precise phase and duty‑cycle control are required to simulate real‑world load conditions. The unit also serves as a reliable pulse source for microcontroller (MCU) firmware validation, enabling developers to test PWM dimming, speed control, and communication protocols without additional hardware. In educational settings, the intuitive rotary encoder with dedicated function keys allows students to explore waveform generation concepts quickly, fostering hands‑on learning. Its compact dimensions (5.04 × 3.11 × 2.17 in) and lightweight design (5.29 oz) make it portable for on‑site diagnostics and troubleshooting of industrial equipment.

FAQ

What is the maximum output current?

The generator can supply up to 0.2 A continuous output, which is suitable for driving small loads, motor driver inputs, and PWM circuits.

Can the two channels operate independently?

Yes, each channel can be set to different frequencies, duty cycles, and phases, or they can be linked for synchronized operation using the SYNC mode.

Is the device safe to use with inductive loads?

While the generator includes short‑circuit protection, it is recommended to use external flyback diodes or snubber circuits when driving inductive loads to prevent voltage spikes.

How is the phase adjusted?

Phase is set via the rotary encoder, with a resolution of 1°, allowing adjustments from 0° to 360° in a single‑step manner.

What kind of warranty does TKXEC provide?

TKXEC offers a standard one‑year limited warranty covering manufacturing defects and provides access to technical support throughout the warranty period.
