Glossary
sampling. The terms are inter-
changeable. See "Repetitive
sampling" in this glossary.
Flash ROM A type of electroni-
cally erasable and programmable
read only memory (EEPROM) used
to store the instrument’s firmware.
The use of this variety of memory
makes it possible to upgrade the in-
strument’s firmware using only a
floppy disk without having to touch
or change any of the internal compo-
nents.
Glitch triggering Glitch trigger-
ing allows the oscilloscope to trigger
on pulses less than or greater than a
selected width.
Internal waveform file format
A binary file format that the oscillo-
scope uses to store waveforms to a
disk. The binary file format uses less
disk space than the text file formats.
Also, the binary file format is a con-
venient method for transporting
waveforms from oscilloscope to oscil-
loscope, or from a disk back into the
oscilloscope.
Interpolate A finite impulse re-
sponse digital filter that makes the
best possible reconstruction of the
waveform. The reconstruction is
done by using digital signal process-
ing to add data points between the
acquired data points. Then, linear in-
terpolation is performed with the
higher sample density.
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 trigger-
ing is like adding a 4-bit logic
analyzer trigger to your oscilloscope.
Memory depth Another term for
record length. See "Record length"
in this glossary.
Offset Another term for Position.
Refer to "Position" in this glossary.
