b) Press the soft key under Trig / Setup to configure the trigger setting (Figure 5-18).
Press the soft key under Src to select among Int (internal), Ext (external), or Man
(manual) for the trigger source.
• Internal trigger source: Press the Trig / Out soft key, then select among OFF,
rising-edge, or falling edge trigger. Press the soft key under Burst / Perd. Use the
navigation wheel with the cursor keys to change the value, and then press
another soft key to finish the entry and exit. Or use the numeric keypad to enter a
desired value and then press the soft key under the desired units to finish the
entry, or the soft key under Cancel to cancel the changes.
• External trigger source: Press the Slope soft key, then select rising edge or falling
edge trigger (Figure 5-19).
• Manual trigger source: Press the Trig / Out soft key, then select among OFF,
rising-edge, or falling edge trigger.
c) Press the soft key under Done to finish the trigger setting.
d) Press the Graph key to view the waveform parameters in the graph mode.

Press the soft keys corresponding with trigger slope
• External gated burst mode:
a) Press the soft key under Polar to choose between Neg and Pos for the polarity of
the external signal (Figure 5-20).
b) Press the soft key under Start / Phase. Use the navigation wheel with the cursor
keys to change the value, and then press another soft key to finish the entry and
exit. Or use the numeric keypad to enter a desired value and then press the soft key
