Programmable dual channel A twochannel pulse/square wave generator with two independent outputs. Each channel's duty cycle and frequency can be controlled, allowing flexible signal shaping. External programming is available via a standard RS232 interface for easy . Wide frequency range and precision Frequency range: 1 Hz to 150 kHz. The device provides precise control over the output signal, with a stated frequency accuracy of 2% and reliable performance in various scenarios. Flexible power options Power it from an external 530 V DC supply or from a USB 5 V DC input. This versatility supports convenient and adaptable sourcing based on user preference and availability. Compact and sturdy design Dimensions: 44 mm x 29 mm x 9 mm. Constructed with sturdy materials to ensure durability in a variety of environments, while remaining compact for easy integration into projects. Use scenarios Lab bench testing: Generate independent dualchannel signals to drive microcontrollers, logic circuits, or motor drivers; adjust frequency and duty cycle via RS232 as needed. Electronics education: Demonstrate timing concepts and waveform relationships using two synchronized or independent channels. Embedded/prototyping projects: Integrate into compact systems where space is limited and precise pulse/square wave signals are required for testing or control.
