Advanced design with audible sound for signal detection in logic circuits. It displays logic levels (high or low) pulses and voltage transients down to 10 nanoseconds. High intensity LED readouts provide instant response to the logic state. Simplified circuitry for fast construction. Detailed instructions, illustrations and testing included.

In kit form, assembly required.
