Quick Reference Labscope Glossary

Trigger Level: The voltage level the Digital Storage Oscilloscope (DSO) looks for to begin drawing a trace.

Trigger Source: The channel (CH1, CH2) that the DSO is looking at for the trigger level.

Trigger Slope: Determines if the trace begins when the voltage is rising or falling as it crosses the trigger level.

Voltage Scale: The amount of voltage each vertical division represents.

Time base: The amount of time each horizontal division represents.

DC coupling: Allows both AC and DC voltages to be displayed.

AC coupling: Allows only the AC voltage component of a signal to be displayed. It filters out DC voltage (a capacitor is used to filter out the DC voltage).

Ground coupling: Allows you to set the zero voltage position on the DSO.

Auto trigger: Allows a scope to begin drawing its trace even if there isn't a trigger set manually.
