Scope Multimeter
General Reference
110
Screen Update Rate
How often the captured data is (updated) displayed on the
screen.
Signal
Detectable voltage, current, or magnetic field, by which specific
information is transmitted in an electronic circuit or system.
Square Wave
A square or rectangular waveform (digital) which alternately
switches high to low (on/off) for specific lengths of time, that has
very fast rise and fall times.
Sweep Scale
The horizontal scale on the grid. Also referred to as time scale or
x axis.
Threshold
The threshold function automatically sets a trigger and
determines a threshold level in the middle of the signal range
(calculated from the Min and Max measurements) to be used as
a reference point to calculate the measurement.
Trace
The actual visible line displayed on the scope screen.
Trigger
A conditional function that initiates if and when a trace is drawn
on the screen.
Trigger Slope
The slope that a trigger source signal must reach before the
trigger circuit initiates a sweep
VAC
Volts Alternating Current
VDC
Volts Direct Current
Vertical Scale
The vertical scale on the grid or (y-axis) represents what is being
measured (voltage, amperage, pressure etc.), and the unit of
measurement it is being measured in.
Volt
Unit of electric potential difference.
Voltage
Electromotive force or potential difference, expressed in volts.
Voltage (inductive) Kick
A voltage, many times higher than the applied voltage, produced
by the collapsing magnetic field in a coil when the current
through it is abruptly terminated.
Waveform
The graphic representation (form) of a signal over time, which
the trace displays on the screen.
Zero Base Line
Reference setting or 0% level of a graph scale.
