Aliasing error
The phenomenon of not obtaining an accurate signal
waveform, due to aliasing distortion. Refer to Appendix 1,
"Background".
ch
Used as an abbreviation for channel. "ch 1" means
channel 1; "1 ch" means one channel.
Cutoff frequency
The frequency for which the output of a filter falls below
1/
√
2(-3 dB) of the input.
DIV A unit corresponding to one division of the chart scale.
Full span voltage The voltage difference corresponding to 6 divisions.
Position
When referring to the position of the waveform along the
voltage axis on the display, this refers more precisely to
the origin, that is the position corresponding to 0 V.
Pre-trigger
Refers to recording the waveform before the trigger. This
value is represented as the percentage of the whole
recording length coming before the trigger.
PT
Voltage transformer
Scaling
The conversion of an input voltage to some convenient
external units.
Shot length
The recording length, which is always expressed in terms
of divisions.
Timer trigger
Trigger function using the clock for fixed real time
triggering.
Trigger timing
Determines whether the trigger controls starting, stopping,
or both.
Unbalanced
input
When one of two input terminals is used as the reference
for the signal.
Word
The amount of memory representing a single sampled
value digitally.
