Memory
Storage component. The place
where digital data is stored.
Mode
A particular kind of operation, or for-
mat
Module (Unit)
A device that provides additional
functionality when installed in the in-
strument
MS-DOS
A DOS (disk operating system) de-
veloped by Microsoft Corporation
(USA), and a registered trademark
of that company
Offset
The amount that a waveform is shift-
ed on the voltage axis by waveform
calculation. An additional value
when scaling
Parameter
A numerical value representing a
feature of a signal waveform, such
as its maximum or RMS value
Peak Hold
Retaining the maximum amplitude
at each frequency point
Position
The location of the zero-volt level.
Pre-Trigger
Time prior to triggering. That is, time
that passes before a trigger event
occurs
Probe
A signal line carrying input signals to
the input circuitry.
PT
Abbreviation of potential transform-
er, a voltage transformer.
Recording Length
An amount signifying the total num-
ber of samples as a number of (dis-
play) divisions
RH
Abbreviation for relative humidity
The amount of vapor contain in one
cubic meter relative to the amount of
saturated vapor at the same temper-
ature, expressed as a percentage
Ripple Component
An AC noise component
RMS
Abbreviation of root-mean-square,
which is the value of AC that per-
forms the equivalent work as the
same value of DC
Sampling
Conversion of an analog waveform
to a digital numeric progression
Sampling Rate
The rate at which the sampling pro-
cess repeats
Scaling
Conversion of measurement values
acquired as voltage into another
physical quantity
Slope
The condition of rising or falling volt-
age
Storage
Writing a waveform (A/D signal) to
memory
TFT
Abbreviation for thin-film transistor
Thermal Head
Provides thermosensitive printing
Threshold
The values of separate High and
Low boundary levels at which an an-
alog signal is converted to a logic
signal
Trigger
An event that initiates an operation.
It signals measurement to begin.
Trigger Source
A signal that serves as the source
required to apply a trigger.
Unbalanced Input
When one of two input terminals
serves as a reference for the other,
as a method for signal input
Word
A unit of data for digital display.
Each sample of an input signal is
converted into one word of digital
data.
Zero Adjust
Making the zero position match the
actual ground level
