ment to make interactive measure-
ments, either with other modules in
the mainframe or with external mod-
ules.
labels Labels are the names of
pods/bits that are used to identify sig-
nal channels or buses. A label is
assigned to identify a bit or set of
bits.
low The most-negative portion of a
logic signal. Used in pattern trigger
measurements, it is represented by
an L in the pattern selector.
manual markers mode The
marker mode for the timing analyzer
and oscilloscope that lets you manu-
ally move the markers using the
knob or the keypad. It is accessed by
selecting the Markers field.
menu field The field to the imme-
diate right of the module field (see
module field). It allows you to
choose the menus related to the
module shown in the module field.
module field The field in the up-
per-left corner of the screen. It
allows you to choose any of the mod-
ules in the mainframe as the working
module. It also allows you to choose
system options and intermodule op-
tions.
offset field For the oscilloscope,
the field that sets the vertical posi-
tion of the waveform on the screen.
Offset is the voltage represented at
the center vertical tick mark in the
waveform display. It is measured in
volts and is viewed in the Offset
field. It is set by using the knob or
the keypad.
panning The action of moving the
waveform along the timebase by
varying the delay value in the Delay
field. This action allows you to con-
trol the portion of acquisition
memory that will be displayed on the
screen. If you choose, you can view
the entire waveform record in acqui-
sition memory. This is normally done
in single-shot mode.
pattern mode For the oscillo-
scope, the trigger mode that allows
you to set oscilloscope to trigger on
a specified combination of input sig-
nal levels. Contrast pattern terms.
pattern terms Analyzer resources
that represent single states to be
found on labeled sets of bits; for ex-
ample, an address on the address
bus or a status on the status lines.
probe field For the oscilloscope,
the field that sets the probe attenu-
ation factor. For example, in the
HP 16532A, the input attenuation
