sified zone to cover the pulse to be measured and adjust the
length of the zone
with B TIME
/ DIV .
6. Adjust Channel 1 POSITION , Channel 2 POSITION ,
and A / B SWP SEP controls to display the A traces above
the B traces .
6. Select the appropriate B TRIGGER SLOPE , and ro
tate the B TRIGGER LEVEL control counterclockwise to the
midrange position , and trigger on the transition to be
measured .
7. Set the A
SEC / DIV
switch to
display the
measurement
points of interest within the graticule area .
7. Read
the time from
the
reference
edge
to the
edge
displayed by the B Sweep on the display .
8. Set UPPER FUNCTIONS - LOWER FUNCTIONS

9. For the
most
accurate
measurement
,
set the B
SEC / DIV
switch
to the
fastest

that
provides
a
useable ( visible ) intensified zone .
Time Difference Between Points On Two Time

Signals (
General
Method )
Time
difference
between pulses on two
time -
related sig
nals can also be measured in a manner similar to that previ
ously described for measuring time difference between two
time related
pulses on single
waveforms using the delta
time
measurement
procedure
.
10. Adjust the B DELAY TIME POSITION control to
move the reference zone to the reference signal on the CH 1
A
trace ( see
Figure
4-8
) .
11. Adjust the A TIME POSITION control to move the
comparison zone to the comparison signal on the CH 2 A
trace ( see
Figure 4-8 ) .
Increased timing
accuracy may be
obtained
by
externally
triggering
the
A Sweep ,
while
internally
triggering the B
Sweep
alternately
from
Channel
1 and
Channel
2 (
triggered
delta time ) . The
following
procedure describes how to
mea
sure from a point of interest on the Channel 1 display to a
point of interest on the Channel 2 display , with or without
the
benefit
of
triggered
delta
time
.
12. To perform a nontriggered measurement see step 13 ,
and to perform a triggered measurement see step 14 .

For nontriggered mode , set the A & B INT switch to CH 1 ,
and for triggered mode set A & B INT switch to VERT MODE
and the A
SOURCE switch to EXT .

,
apply
the
reference signal to
the CH 1

connector and
apply
the comparison signal to the CH 2 input connector . For trig
gered measurement , the signal to EXT INPUT connector
must also be
applied to the
CH 1 input
connector
