To change the display options of waveform database data on the graticule, use
the procedure that follows:
Overview To customize the database display Related control elements & resources
Prerequisites 1. The instrument must have a waveform assigned to one of
the waveform databases.
See To Set Up a Waveform Database on
page 3--162.
Access the
Wfm Database
Setup dialog box
2. Open the Waveform Database dialog box by selecting
Wfm Database in the Setup menu.
Set Persistence 3. Choose a persistence mode.
Infinite: Choose Infinite to continue displaying
waveforms as they accumulate until the selected
database is cleared manually or by a control change.
Variable: Choose Variable to display accumulated data
in the specified database until the user-specified
waveform count is surpassed. Each waveform
accumulated beyond the count removes the oldest
waveform accumulated earlier in the database.
Waveforms: For Variable persistence, use the
Waveforms entry box (or the sliding control above it) to
set the Waveforms count. The count applies to the
currently selected database when Variable persistence
mode is set. Enter values directly with this control using
the up/down arrows, the pop--up keypad, or an
externally connected keyboard.
Samples: The Samples field is a readout sample count
currently in effect for the currently selected database
when Variable persistence mode is set. This count is not
settable directly, but instead derives from the product
two values: the current Waveforms setting in this dialog
box and the setting for Record Length in the Horizontal
Setup dialog box.
