You can push the MODE softkey to move through the functions in the sequence shown,
or you can push

to return directly to the OTHER modes menu.
Each option in the PULSE menu is given below.
•
OUTPUT @ SCOPE Shows the location of the signal output. If the signal does not
show on the oscilloscope, push

. To disconnect the signal, push

.
•
AMPL Shows the output level. You can select 2.5 V, 1.0 V, 250 mV, 100 mV,
25 mV, or 10 mV.
•
TRIG If you use the external trigger, use this key to move through the trigger
settings. The available trigger settings are: off, /1 (trigger signal shows on each
marker), /10 (trigger signal shows on every tenth marker), and /100 (trigger signal
shows on each 100 markers). You can also toggle the trigger off and on. Push

.
•
MODE Shows you are in PULSE mode. Use the softkey to change modes and open
the menus for the other oscilloscope calibration modes.
Default Pulse settings are 100.0 ns width and 1.000 ms period. To change these values,
you have some options. Usually, you will record values for pulse width and period. To
do this, record the pulse width value with units first, followed immediately by the period
value and units, followed by

. For example, you could record a pulse width of
50 ns and a period of 200 ns with the subsequent sequence:
             
.
To change only the pulse width, record a value in seconds. You can record this value with
units (for example, 200 ns) or without units (for example, 0.0000002). To change only
the period, record a frequency with units (for example, 20 MHz, this changes the period
to 50 ns).
