Model 5326/27A
Operation
6
7
Single Time Interval
1.
Set SAMPLE RATE control slightly clock¬
wise out of OFF.
2.
Set FAST/NORM/HOLD switch to NORM.
3.
Set FUNCTION switch to T.I. A to R.
4.
Set
MIJTLI FLIER
switch
for
desired
resolution.
5.
If start-stop signals are from a common
source, connect signal to CHANNEL A in¬
put
and
set
CHK-SEP-COM
switch
to
COM.
If start-stop signals are from sepa¬
rate sources, connect start signal to CHANNEL
A input and stop signal to CHANNEL B
input and CHK-SEP-COM switch to SEP.
6.
Set CHANNEL A SLOPE switch to + for
triggering on positive slope of signal or to -
for triggering on negative slope of signal.
7.
Set CHANNEL A LEVEL and
ATTEN
switches to start measurement at desired
voltage level.
Select AC or DC coupling.
For frequencies below 100 kHz, use MARKER
A OUTPUT jack on rear panel to display
starting point on an oscilloscope.
8.
Set CHANNEL B, AC-DC, LEVEL, SLOPE,
and ATTEN controls to stop measurement
at desired level.
For frequencies below
100 kHz, use MARKER B OUTPUT to dis¬
play stopping point on oscilloscope.
9.
Adjust SAMPLE
RATE control for con¬
venient measurement interval.
NOTE
There must be at least 150 ns between
the STOP pulse (Channel B trigger)
and the next START pulse (Channel
A trigger).
Time Interval Average
1.
Set SAMPLE RATE control slightly clock¬
wise out of OFF.
2.
Set FAST/NORM/HOLD switch to NORM.
3.
Set FUNCTION switch T.I. AVG A.
4.
Set MULTIPLIER switch to number of time
intervals to be averaged.
5.
If start-stop signals are from a common
source, connect signal to CHANNEL A input
and set CHK-SEP-COM switch to COM.
If start-stop signals are from separate sources,
connect start signal to CHANNEL A input
and stop signal to CHANNEL B input and
CHK-SEP-COM switch to SEP.
6.
Set CHANNEL A SLOPE switch to + for
triggering on positive slope of signal or to -
for triggering on negative slope of signal.
7.
Set CHANNEL A, LEVEL, and ATTEN to
start the measurement at desired voltage
level.
Select AC or DC coupling.
For fre¬
quencies below 100 kHz, use MARKER A
OUTPUT jack on rear panel to display start¬
ing point on oscilloscope.
8.
Set CHANNEL B, AC-DC, LEVEL, SLOPE,
and ATTEN to stop the measurement at
desired level.
For frequencies below 100
kHz, use MARKER B OUTPUT to display
stopping point on oscilloscope.
9.
Adjust SAMPLE
RATE control for con¬
venient measurement interval.
NOTE
STOP to START delay must be M50
ns and input rate should not be 10
(M and N integers).
