This page lists and explains some of the terms you may find in the manual or on the TiePie engineering website.
When sampling a signal with a too low sample frequency, a signal with a wrong (apparent) signal frequency is displayed. This is called aliasing.
An Arbitrary Waveform Generator is a function generator that can generate arbitrary signals.
When an unknown signal is connected to the oscilloscope, the easiest way to setup the oscilloscope is by using the Auto setup function. The Auto setup function will change various settings of the instrument in order to display a signal in a convenient way.
The bandwidth of an instrument determines the frequency spectrum that can be measured.
The common-mode rejection ratio indicates the capability of an input to reject input signals common to both input leads.
A data logger (or transient recorder) is a direct registering instrument to display signal voltages, plotted against time (Yt) or against another signal voltage (XY).
To increase the input range of a differential input, a special differential attenuator is required.
A differential input is not referenced to ground, but both sides of the input are "floating".
Edge trigger is used to trigger on a rising, a falling or any edge in a signal.
An oscilloscope measuring mode to capture occasionally changing signal patterns.
Interval trigger allows an oscilloscope to trigger on periodical signals with a period time longer than or shorter than a specified time or inside or outside a specified time frame.
The multimeter (or voltmeter) is an instrument that performs a measurement on a signal and displays one or more specific properties of that signal as numeric values or with a gauge.
An oscilloscope is an instrument for observing the exact wave shape of varying signal voltages. Measured signals are usually plotted against time (Yt) or against another signal voltage (XY) in a graph.
Pre trigger allows to capture signals that occur before the trigger moment.
An oscilloscope probe is the connection between the input of an oscilloscope and the device under test.
Pulse width trigger allows an oscilloscope to trigger on positive or negative pulses shorter or longer than a specified time.
The resolution determines how accurate the amplitude of a signal can be measured.
The rate at which samples are taken is called the sample frequency, the number of samples per second.
When sampling an input signal, the magnitude of the input signal is measured at fixed intervals.
The signal coupling or input coupling selection determines how the signal on the input is passed on.
A spectrum analyzer is an instrument that graphically displays signal magnitude against frequency.
The combination of sampling frequency and record length forms the time base of an oscilloscope.
The Total Harmonic Distortion (THD) is a measure of the distortion in a signal.
Oscilloscope channel trigger types can have an additional trigger condition and corresponding trigger condition time that define a time condition for the trigger type.
Trigger delay allows to start measuring a specified time after the trigger occurred.
Trigger hold-off defines the time that the trigger system is disabled after starting a measurement.
The trigger hysteresis of an oscilloscope channel determines the sensitivity of the trigger system for signal changes.
The trigger level of an oscilloscope channel determines at which level in a signal the oscilloscope will trigger.
Trigger time-out defines the time that the system will wait for a trigger before a trigger is forced
The trigger type determines what signal properties trigger the measurement.
Triggering determines based on predefined conditions when capturing and displaying the input signals starts.
