Use the numeric keypad to specify the sweep mode:

halts, displaying the stop value.
1 Continuous Continuous sweep. The sweep steps from the start value to the stop value,
and then repeats.
Trigger SWE:TRIG page 4-159
Use the numeric keypad to specify the external trigger mode:
0 Off External trigger is disabled. Control the triggering manually using the
sweep control screen of Fig. 3-80.
1 Start The trigger starts the sweep. At the end of the sweep the trigger latch
resets, ready for the next input. During the sweep, trigger inputs are
ignored.
2 Start/Stop The first trigger starts the sweep, the next trigger pauses it. A further
trigger causes the sweep to resume from the point at which it paused. The
trigger latch resets after each start/stop.
3 Step Each trigger increments the sweep by the size of the frequency/level step.
The trigger latch resets after each step.
The trigger input has a pull-up resistor, so a switch closure is treated as a trigger event.
Note: You can always control the sweep from the front panel, regardless of the trigger mode.
Slope SWE:TRIG:SLOP page 4-159
