Attenuation
The degree of reduction in amplitude as a signal passes
through an attenuating device such as a probe or attenuator.
That is, the ratio of the input measure to the output meas-
ure. For example, a lOX probe will attenuate, or reduce, the
input signal's voltage by a factor of 10.
Auto-level Trigger Mode
A trigger mode in which the instrument determines the
peak values of the incoming signal and sets the trigger level
to its midpoint. This allows you to display a waveform
without setting the trigger level.
Automatic trigger mode
A trigger mode that causes the system to automatically ac-
quire if triggerable events are not detected within a speci-
fied time period. Useful for displaying a waveform even
though the oscilloscope has not been triggered.
Auto Setup
A function that automatically sets front-panel controls in a
manner that depends on the signals applied to channels
1
and
2,
speeding the process of setting up the instrument.
Bandwidth
The highest frequency signal the oscilloscope can acquire
with no more than
3
dB (X .
707)
attenuation of the original
(reference) signal.
Baud Rate
The rate at which two connected electronic devices ex-
change data.
Brightness
The intensity with which the phosphor glows on the screen.
Calibration
The adjustment of the instrument performance to meet pub-
lished specifications or to verify such performance, accord-
ing to external reference standards.
