Note
In ROLL operating mode, the trigger level and
trigger source functions are inoperative. ROLL
mode is not possible in the range from 2 ms/div
to 0.2 µs/div or 0.1 µs/div in the case of the OS-
3060 D.
(4) Single mode in NORM mode
Proceed as follows:
a) Set the Time/div switch to a switch position
between 5 µs/div and 0.2 s/div. This selects
NORM operating mode in storage mode.
b) Press the "SINGLE" button. The red LED
under the button cap is briefly lit and this
indicates that a trace is displayed as soon as
the trigger signal occurs.
c) After triggering, the red LED under the cap
of the SINGLE button goes out.
d) Once the sampling process has completed, a
new signal waveform is shown on the screen.
The SINGLE sequence is terminated, the on-
screen signal is paused and the LED under the
cap of the HOLD button is lit.
Note
If the trigger signal is not indicated in SGL
mode, the red LED under the button cap
remains lit until there is a trigger signal.
SINGLE mode does not work with the following
functions: Average (AVG), ROLL, EQUIV or when
the time base is expanded (MAG).
(5) HOLD (ALL) function
If you press the HOLD (ALL) button in ROLL,
EQUIV or NORM mode, the sampling process
stops and the measuring signal stored in
memory in 1-second fractions is displayed as a
"still image".
(6) Recording and reproduction of signals
The SAVE/RECALL function is ideal for com-
paring a specific signal waveform to other sig-
nals. To do this, the "paused" signal is placed in
the "clipboard memory" until it is retrieved
using the Recall key or it is cleared. "Save A"
(SA) saves CH 1 = channel 1, SAVE B (SB) saves CH
2 = channel 2.
To record a signal, proceed as follows:
a) Use the HOLD button to stop the current
sampling process.
b) Press the SAVE button in the STORAGE MODE
panel. Once the signal has been stored in the
recording memory, the LED under the cap of
the SAVE button is briefly lit. The signal has
then been recorded.
(7)Reproducing the recorded signal waveform
(= RECALL)
If you want to check the signal immediately
after storing it, proceed as follows:
a) Press the RECALL button once; the signal that
was stored in recording memory A (SA)
appears with the recorded VOLTS/DIV and
TIME/DIV settings, regardless how the VERTI-
CAL MODE switch is set.
If you press this button again, the recorded
signal waveform from recording memory B
appears. If the RECALL button is pressed a
third time, both A and B appear on the
screen, together with the stored settings.
If you press the RECALL button a fourth time,
this clears the "clipboard memories" (A and
B) and both the signal waveforms with their
respective settings.
b) Reproduced signal waveforms cannot be
moved upwards or downwards by using the
Position knob (16 or 17).
(8) X-Y plotter output (RS-232) with PLOT button
A signal is only available on the plotter inter-
face for printout if you first pressed the HOLD
