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 .
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 165.
•
Mask
— The pass/fail status is evaluated periodically. When the
evaluation of the testing period results in a failure, the trigger output
pulses high (+5 V). Otherwise, the trigger output remains at low
(0 V). See
Chapter 15 , “Mask Testing,” starting on page 271.
• Waveform Generator 1/2 Sync Pulse — All of the waveform generator
output functions (except DC, Noise, and Cardiac) have an associated
Sync signal:
The Sync signal is a TTL positive pulse that occurs when the
waveform rises above zero volts (or the DC offset value).
See Chapter 17 , “Waveform Generator,” starting on page 287.
The TRIG OUT connector also provides the User Cal signal. See "To
perform user calibration" on page 342.
Setting the Reference Signal Mode
The 10 MHz REF BNC connector on the rear panel is provided so you
can:
• Supply a more accurate sample clock signal to the oscilloscope, or
