HPS10 PersonalScope
Press the 't-V/div'-key to set the cursorkeys
action into 'timebase' mode.
Press the 'left' or 'right' cursor keys to increase
or decrease the timebase (time/div).
Note:
•
Changing the timebase
switches the autorange mode immediately
off. (Fig 37)
•
The timebase or sensitivity cannot be
changed into hold mode.
•
Pressing the 't-V/div' key into hold mode
toggles the screen between the two stored
waveforms.
•
At higher timebase (2us and faster) the scope
uses oversampling mode, only repetitive
signals are correctly displayed.
•
Use the minimum time base (0.2 microsec)
as a starting point when measuring a signal
and select longer time bases until the signal
is displayed properly. Otherwise the display
may not correctly reflect the signal under
measurement due to aliasing.
