repetitive mode The field that
causes the oscilloscope to start the
next acquisition as soon as the pre-
vious acquisition has been
completed and the data has been dis-
played (that is, to take single
acquisitions repetitively).
run, repetitive mode See
repeti-
tive mode.
run, single mode See
single mode
single mode
The field that causes
the oscilloscope to make a single
data acquisition and display the re-
sults of that acquisition on the
screen. In this mode, the Run field
must be touched each time you want
a new acquisition and, consequently,
a new screen update.
source field
The field that allows
you to select a channel for edge trig-
gering and trigger level setting.
toggle field
A dark-blue field that
has only two options. When the
field is touched, the current option
in that field will change (toggle) to
its other option.
touchable field Any dark-blue
field on the screen is a "touchable"
field. When you touch a dark-blue
field, the field toggles to another op-
tion, a pop-up menu appears, or the
field turns light-blue to activate the
knob for that field.
trigger point The point at which
the voltage on the signal source in-
put waveform equals the trigger
level voltage value set in the Level
field of the trigger menu.
vertical sensitivity The voltage
value that determines the amplitude
of the waveform on the screen. It is
measured in volts per division and is
viewed in the V/Div field. It is set by
using the knob or the keypad.
when field This field is part of the
Pattern Mode menu. It is a toggle
field that allows you to choose
whether to trigger on the selected
pattern when it is entered, exited or
meets a duration specification.
zooming The action of expanding
and contracting the waveform along
the timebase by varying the value in
the s/Div field. This action allows
you to select specific portions of a
particular waveform in acquisition
memory that will be displayed on
the screen. You can view any por-
tion of the waveform record in
acquisition memory. When used in
conjunction with panning, zooming
is very useful in displaying single-
shot waveforms.
