How to Verify Pulse Capture
gjh063.eps
The pulse mode is a general-purpose pulse generator with pulse widths from 4 ns to 500
ns. It can be used to check many of the advanced trigger functions of an oscilloscope,
such as pulse capture. You can press the MODE softkey to cycle through the functions in
the order shown, or you can press
P
to return directly to the OTHER modes menu.
Each option in the PULSE menu is described below:
•
OUTPUT @ SCOPE Indicates the location of the signal output. If the signal does
not appear on the oscilloscope, press
O
. To disconnect the signal, press
Y
.
•
AMPL Indicates the output level. You can select 2.5 V, 1.0 V, 250 mV, 100 mV,
25 mV, or 10 mV.
•
TRIG If you are using the external trigger, use this key to cycle through the trigger
settings. The available trigger settings are: off, /1 (trigger signal appears on each
marker), /10 (trigger signal appears on every tenth marker), and /100 (trigger signal
appears at every 100th marker).
•
MODE Indicates you are in PULSE mode. Use the softkey to change modes and
open menus for other oscilloscope calibration modes.
Default Pulse settings are 100.0 ns width and 1.000 ms period. To change these values,
you have several options. Usually, you will enter values for both pulse width and period.
Do this by entering the pulse width value with units first, followed immediately by the
period value and units, followed by
E
. For example, you could enter a pulse width
of 50 ns and a period of 200 ns with the following sequence:
5 0 b K b H 2 0 0 b K b H E
To change only the pulse width, enter a value in seconds. You can enter this value with
units (e.g., 200 ns) or without units (e.g., 0.0000002). To change only the period, enter a
frequency with units (e.g., 20 MHz, changing the period to 50 ns).
