Linear interpolation Another
term for connected dots. A straight
line is drawn between two adjacent
data points.
Logic triggering Logic triggering
allows you to qualify the trigger
event further than the standard edge
trigger mode. Basically, logic
triggering is like adding a 4-bit logic
analyzer trigger to your oscilloscope.
Mainframe calibration The basic
or normal level oscilloscope
calibration that allows the
oscilloscope to establish the
calibration factors for the plug-in
slots, independent of the plug-ins.
Memory depth Another term for
record length. See "Record length"
in this glossary.
Normal accuracy calibration
The basic calibration of the
mainframe and plug-ins independent
of each other. You should calibrate
both the mainframe and the plug-ins
to normal accuracy before
performing a best accuracy
calibration.
Offset Offset moves the waveform
vertically on the display. It is similar
to the vertical position control on
analog oscilloscopes except that it is
precisely calibrated. The offset
voltage is the voltage at the center of
the graticule area.
Pattern triggering Pattern
triggering qualifies the trigger event
by having the oscilloscope search for
a 4-bit pattern across the
oscilloscope inputs. You can define
the pattern as a combination of
highs, lows, or don't care levels.
Voltages above the trigger level are a
high, and voltages below the trigger
level are a low.
Pixel memory A pixel memory is
a volatile, screen image, storage
area. It is essentially a snap shot of
the display and has no vertical or
horizontal scaling factors associated
with it.
Plug-in A plug-in installs into one
or more of the slots in the front of
the oscilloscope. A plug-in performs
analog signal conditioning for the
oscilloscope and supplies a trigger
signal to the trigger/time base board
inside of the oscilloscope.
