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).
