HOLDING THE SCREEN
Press the ‘Memory’-key to freeze the waveform
on-screen.
It may be useful to "freeze" certain signals on your
screen. This will allow the user to study the signal or
perform measurements with the markers. (Fig 44)
Remarks:
• Most of the keyboard functions are disabled.
• Pressing the Memory key immediately stops
sampling at slow timebases. The rest of the sample
buffer will be cleared.
• ‘HOLD’ will be displayed inverted. (1)
• Releasing the ‘Hold’-mode will remove the
waveform from the screen.
STORE A SCREEN
Press the Memory key to “Hold” the waveform on-
screen.
A long keypress of the ‘Trigger’-key mode stores the
current screen into memory. (2)
RECALL MEMORIES
Pressing the ‘t-V/div’-key when in hold mode toggles
the screen between the frozen waveform and the stored
waveform. (Fig 45)
Notes:
• The store and recall- function is only available in
‘HOLD’-mode
• All setting such as timebase, input sensitivity, input
coupling, probe setting and readouts are also stored
into memory.
