Store Mode
The 222PS can display signals in store and nonstore modes. In
store
mode
, the instrument displays traces between trigger events. In
nonstore mode
, the 222PS displays traces only until the next display
update (about 30Ăms) or until the next trigger. If a trigger does not
occur in 30Ăms, the instrument blanks the display. Nonstore mode
operates similarly to a conventional analog oscilloscope displaying a
signal that is triggered at the beginning of the trace.
SingleĆsequence mode is the exception to this rule Ċ when in singleĆ
sequence and nonstore modes, the 222PS displays the trace until you
press the
INIT
button to reacquire the signal.
You can tell whether the instrument is in store or nonstore mode by
looking at the bottom readouts. When the 222PS is in store mode, an
s
t
symbol appears in the middle of the bottom readout. In nonstore
mode, this space is blank. Figure 3Ć30 shows a store mode readout.
