Screen Buttons
The rows of buttons below and to the right of the display that
select items in the menus.
Selected Waveform
The waveform on which all measurements are performed and
which is affected by vertical position and scale adjustments.
Signal Path Compensation (SPC)
The ability of the oscilloscope to minimize the electrical offsets
in the vertical, horizontal, and trigger amplifiers caused by
ambient temperature changes and component aging. You should
run SPC when the ambient temperature varies more than 5 C
from the last SPC or before performing critical measurements.
Single Sequence
A single shot acquisition if Sample or Peak-detect acquisition
mode is selected. A series of N acquisitions if Average or
Envelope acquisition mode is selected (N is the number of
averages or envelopes).
Standby (STBY)
The off-like state when the instrument in not in use. Some
circuits are active even while the instrument is in the standby
state.
TekProbe Interface
An interface that communicates information between a probe
and the oscilloscope, such as the probe type and its attenuation
factor. The interface also supplies power to active probes.
