(6) SINGLE SWEEP OPERATION
This
mode
of
display
is useful
for
looking
at
non-
synchronous or one time events.
Procedure:
1. Set the TRIG MODE @0 to either AUTO or NORM. Apply
a signal of approximately the same amplitude and fre-
quency as the signal that is to be observed as the trig-
ger signal and set the trigger level.
2. Set TRIG MODE to RESET — observe that the READY
indicator LED lights to indicate the reset condition. This
LED goes out when the sweep period is completed.
3. After the above set-up is completed the scope is ready
to operate in the SINGLE sweep mode of operation after
resetting the instrument using the RESET switch. Input
of the trigger signal results in one and only one sweep
and READY indicator LED goes out.
NOTE:
With the HORIZ MODE set to ALT the simultaneous
observation of the A sweep and B sweep waveforms
at SINGLE sweep mode is not possible. Also for ALT
(vertical MODE) mode operation simultaneous obser-
vation is not possible. Set the unit to the CHOP mode
in this case.
[B] READOUT
OPERATION
(CS-5130 only)
1 CRT surface readout
By rotating the INTEN (READOUT) controller (8) clock-
wise up to the very end, characters are displayed on the
CRT. Adjust the brightness as necessity requires. The
CH1 and CH2 scale factors are displayed in the lower
part of the CRT in accordance with setting of the MODE
select switch (1). The sweep scale factor is displayed in
the lower right part. By pulling the < » POSITION/
PULL x 10 MAG switch @, a tenth scale factor of the A
and B SWEEP TIME/DIV control @) @ is displayed.
NOTE: When the readout values are displayed, brilliance
modulation may influence the real-time waveform
in some cases. In such a case, rotate the INTEN
(READOUT)
control
fully counterclockwise.
The readout function will be turned OFF, and the
brilliance modulation on the real-time waveform
will disappear.

Cursor measurement
AV1:
Set the MODE select switch @) to ALT and the
CURSORS
select switch @ to AV1, and two
horizontal cursor lines are displayed on the CRT
and voltage difference between cursor lines cal-
culated in accordance with setting of the CH1
VOLTS/DIV control @) is displayed in the upper
right on the CRT. By setting the CH1 VARIABLE
controller G) to the UNCAL position, voltage ra-
tio is displayed.
Move the cursors to the positions to be measured
with the AREF controller @® and A controller @.
20
AV2:
AT:
1/AT:
}
Set the CURSORS select switch @ to AV2, vol-
tage difference in accordance with the CH2 range
setting is displayed in the upper right on the CRT
similarly with the above AV1.
Set the CURSORS select switch @ to AT, and
two vertical cursor lines are displayed on the CRT
and time difference between the cursor lines cal-
culated based on the A sweep scale factor dis-
played in the lower right is displayed in the upper
right. By setting the SWEEP VARIABLE controller
@) to the UNCAL position, time ratio is displayed.
Set the CURSORS select switch @) to 1/AT, and
two vertical cursor lines are displayed on the CRT
and frequency between the cursor lines calculat-
ed based on the A sweep scale factor displayed
in the lower right is displayed in the upper right.
By setting the SWEEP VARIABLE controller @ to
the UNCAL
position,
phase
difference
is dis-
played.
