What is a Transient Signal? ? ? § § Signals which last for a very short period of time are referred to as “ TRANSIENT Signals”. Examples: Switch bounce, Shock wave generated from an impact test, Seismic Signals. .

Run Control Menu Run/Stop (Green): Instrument is continuously acquiring data n Run/Stop (Red): Instrument has stopped Acquiring data n SINGLE : Instrument will wait for the user defined event (typically voltage set by the user) n

Trigger Menu Trigger tells the oscilloscope when to start acquiring data. Normally edge triggering is done

Triggering modes Normal mode: Displays a waveform when the trigger conditions are met. Used for very short signals (*****) n Auto mode: Displays a waveform when the trigger conditions are met. Used for all signals n Auto-level mode: can be used only when EDGE is selected on the front panel n

Coupling Modes n DC Coupling : Allows both D. C. and A. C. signal to flow in to the trigger path. n AC coupling : Allows A. C only

SWITCHES & LOGIC GATES

Switches and Related Terminology Pole - number of switch contact sets. n Throw - number of conducting positions, single or double. n Way - number of conducting positions, three or more. n Open - off position, contacts not conducting. n Closed - on position, contacts conducting, there may be several on positions. n

Single pole Double Throw Switch (SPDT-Switch) SPDT can be “ON” in both positions, switching on a separate device in each case. It is often called a “change over switch”.

Basic Logic Gates

Flip-Flops and Latches Flip-Flop and Latches are sequential circuits which are built from basic logic gates. n Flip-Flop and latches form the fundamental unit of “memory” in modern computers. n Each flip-flop can store 1 bit of information. n
