Description:
It is designed for the requirements of digital pulse circuit experiment, digital logic circuit experiment and curriculum project.
Details:
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.
