cable. Connect the SMA short, to the remaining end of the cable.
Now connect the male SMA T connector to
Ch 1
through an SMA
female to BNC male adapter.
■
Set the pulse generator output for a positive-going pulse with a rise-
time as shown in the table for your instrument, and for the fastest
possible repetition rate (at least 1 kHz). (See
on page 247.)
■
Set the pulse generator output for about 500 mV. (This amplitude can
be adjusted later to get a 5-division pulse on screen.)
c. Modify the initialized front-panel control settings:
■
Power on the pulse generator.
■
Touch
Utilities
, select
User Preferences
, select the
Units
tab, and
then select the
1-2-5
button.
■
Readjust the Trigger
Level
knob so the trigger level is about 50% of
the rising edge of the positive pulse.
■
Press
Autoset
. You may see both positive and negative pulses.
Adjust the Trigger
Level
knob so the trigger level is about 50% of
the rising edge of the positive pulse.
■
From the button bar, touch the
Horiz/Acq
button and select the
Acquisition
tab. Press the
RT
button to turn on Real Time Only.
■

■
Adjust the generator output or instrument vertical scale and position
as necessary to obtain at least
5 divisions
of the
positive
pulse.
d. Set up for statistics measurements:
■
Press
Run/Stop
button to freeze the display.
■
From the button bar, touch
