Digital Circuits Synthetic Experimental System

Digital Circuits Synthetic Experimental System China Engineering Lab Training System Suppliers

The for the experiments covering the course of digital electronics technology which addresses the requirements of colleges or vocational schools.

It is made of PCB and all the connections are accomplished on the backside of the board
while the symbols and diagrams specific to each module are clearly silk-screened on the
faceplates. DIP IC sockets and sockets for components connection are provided. Four blue
sockets for fixing the experimental modules and a breadboard are provided.
Two-way ±5V@0.5A and two-way ±15V@0.5A, with the function of short-circuit protection
and auto-recovery for each circuit.
It outputs base frequency, divide-by-2, divide-by-4 and divide-by-8 of BCD code and the
output for the base frequency are: 1Hz, 1kHz, 20kHz.
One-way continuous adjustable counter pulse: 0.5Hz~300kHz
Positive & negative single pulse source
Five-state logic test pen is designed by the logical program device and with different
colors of LED for output indication.16-bit logic switches and 16-bit level indication,
6-digit hex seven-segment decoder display, 4 thumbwheel switches (up/down decimal counter).
Multi-function intelligent tester is MCU-based and available to identify the types of TTL,
CMOS ICs and available as a frequency meter (range: 1Hz~1MHz).
It is available to used as a period counter and pulse No. counter etc.
Components: Pushbuttons, relay, multi-turn potentiometer (10KΩ) and carbon-film
potentiometer(100KΩ) etc. are installed on the panel.
