Memory Bar and Measurement Field
The memory bar is a horizontal line below the waveform display area which
shows what fraction of acquisition memory is displayed and the position of
the display with respect to acquisition memory. When the analyzer is
stopped, you can change the size of the display with respect to acquisition
memory using the Time/Div control, allowing you to zoom in on a specific
portion of memory.
Below the memory bar is the measurement field. This area is used to display
results for single- and dual-channel measurements, activity indicators, trigger
settings, error messages, and status messages.
Softkeys
Softkeys are shown along the bottom of the display. Some softkeys have an
immediate action, such as taking you to another menu or initiating a
measurement.
Other softkeys allow you to scroll through a list of choices, such as channels
or trigger operators. You can scroll through the choices by pressing the
softkey repeatedly. For some softkeys, you can use the Entry knob to scroll
through the choices. For channel lists, you can always use the Select knob or
Entry knob to scroll through the choices.
Occasionally a softkey label is displayed with two choices below it, one of
which is highlighted. The highlighted choice is the one that is currently
active. Pressing the softkey toggles the highlight to the other choice.
When several softkeys are displayed with a labeled bar over them, it means
that either the softkeys are related or that the choices are mutually exclusive.
When using the HP 54620C color logic analyzer color palettes, some
channel-specific softkeys display the color assigned to the particular channel.
See “Using Color” in this chapter for more information about assigning colors
to channels.
