GLSD-1 Digital Circuit Experiment Box

I、Equipment Overview

GLSD-1 Digital Circuit Experiment Box is mainly used for digital circuit experiments in electronics. It adopts a modular structure, and each module is independent of each other. Through the combination of different components in each component area, a variety of experimental circuits can be formed. The front of the experimental template is printed with a circuit diagram, and the back is equipped with devices. Each point to be tested in the experimental circuit is equipped with a test hole. It is easy to use, reliable in contact, and has a long life and high efficiency. The main experimental unit is completed with a matching experimental module. The experimental expansion module can be selected according to different needs to complete the relevant experimental content, which can meet the needs of digital circuit course experimental teaching.

This product is suitable for undergraduates, junior college students, and students in vocational colleges who offer experimental teaching of related courses such as "Digital Electronic Technology" and "Pulse Circuit". It is also suitable for product development and scientific research.

Ⅱ、Equipment configuration

1. Power supply: standard three-port power socket: directly connected to external AC 220V, the 220V AC is converted into ±l5V/0.5A, ±5V/0.5A through the power conversion unit inside the experimental box, all with short-circuit overload protection, automatic recovery function, connected to the main panel of the experimental box.

2. Equipment panel: the motherboard is made of 2mm thick printed circuit board, with component graphic symbols and corresponding connections printed on the front, printed circuits on the back, and related components soldered.

3. Signal source: provide a set of clock signal sources; adjustable clock signal source (low frequency, high frequency); single pulse source: positive and negative pulse output.

4. Logic input and display circuit:
