IDL-800
DIGITAL LAB

    IDL-800 Digital Lab is designed to accomodate digital circuits evaluators. The main purpose of this lab is to enable the users to acquire conveniently a DC power supply, a signal generator, a digital voltage meter, an eight bits LED display, two digital 7 segment LED displays and logical function switches.

    To allow people to operate it and in order to properly connect (said interfacing) between the IDL-800 and peripheral instruments, the solderless breadboard is fixed on the lower part, and four point/banana socket/BNC socket exchange adapters are located at the right part of the Lab.

    The details are as follows:
