Utility Settings
• Preserve — to make the oscilloscope remain in the acquisition mode you
have chosen when the [AutoScale] key is pressed.
Setting the Oscilloscope's Clock
The Clock Menu lets you set the current date and time of day (24-hour format).
This time/date stamp will appear on hardcopy prints and directory information on
the USB mass storage device.
To set the date and time, or to view the current date and time:
1 Press [Utility] > Options > Clock .
2 Press the Year , Month , Day , Hour or Minute softkey; then, rotate the Entry knob to
set to the desired number.
The hours are shown in the 24-hour format. So 1:00 PM is hour 13.
The real-time clock only allows selection of valid dates. If a day is selected and the
month or year is changed so the day is invalid, the day is automatically adjusted.
Setting the Rear Panel TRIG OUT Source
You can choose the source of the TRIG OUT connector on the rear panel of the
oscilloscope:
1 Press [Utility] > Options > Rear Panel .
If the Rear Panel softkey does not appear, it means neither mask testing nor the
waveform generator is licensed, and oscilloscope triggers are sent to TRIG OUT
by default.
2 In the Rear Panel Menu, press Trig Out ; then, turn the Entry knob to select from:
• Triggers — Each time the oscilloscope triggers, a rising edge occurs on
TRIG OUT. The rising edge is delayed 30 ns from the oscilloscope's trigger
point. The output level is 0-5 V into an open circuit, and 0-2.5 V into 50
Ω
.
See Chapter 10 , “Triggers,” starting on page 125.
