Using the Agilent 81101A
The Output Screen
Pulse Width Parameter
Set the width of the output pulse. There are three width formats
available:
W
IDTH
(select W
IDTH
)
The absolute pulse width measured from the start of the leading edge
to the start of the trailing edge. In this format, the pulse width is
independent of changes in pulse period and delay.
D
TY
C
YC
(select D
UTY
C
YCLE
)
The duty cycle is the pulse width measured from the start of the
leading edge to the start of the trailing edge expressed as a
percentage of the period. In this format, if you adjust the period, the
absolute width is adjusted to maintain the duty cycle.
T
RA
D
EL
(select T
RAIL
D
EL
)
The trailing delay is the absolute delay from the start of the pulse-
period to the start of the trailing edge. In this format the trailing edge
remains fixed relative to the start of the pulse period if you adjust the
pulse delay (leading edge delay) or the pulse period.
NOTE
You cannot have the width format set to D
TY
C
YC
and the leading/trailing-
edge format set to percentage of width (L
EAD
E
D
%/T
RAIL
E%) at the same
time.
Leading Edge Parameter
Set the leading edge transition time of the pulse, measured from 10% to
90% of the pulse amplitude. There are two formats available:
L
EAD
E (select A
BSOLUTE
)
The absolute transition time measured from 10% to 90% of the pulse
amplitude. In this format the leading edge is independent of the pulse
width.
L
EAD
E% (select %
OF
W
ID
)
The absolute transition time expressed as a percentage of the pulse
width. In this format, if you adjust the pulse width, the transition time
is adjusted to maintain the edge time as a percentage of the width.
