Elenco Upgrade Kit SC500 to SC750 - Manual (Page 104)

Place Winscope in Wait mode by clicking on the button for it, then
slowly press the On-Line button several times. Now turn off the
slide switch (snap part S1) and press On-Line again. Then turn the
switch back on.
You see that in Wait mode Winscope scans
(“waits”) until it sees a waveform that exceeds the trigger level you
set, then stops. With a strong signal it will make one scan and then
stop, whereas if no signal is present it keeps scanning until it finds
one. You could use this to sense when someone has turned on the
circuit.

You can change the color of the waveform: select <Options>, then
select <Colors>, then select <Y1 Trace>. Now select the color you
like and click <OK>.
Now we will combine the wait and storage modes to display several
waveforms that this circuit can create. You should have the circuit
on with the adjustable resistor at mid-range and Winscope in Wait
mode. Now turn on Storage mode. Now change the color of the
Y1 trace. Move the adjustable resistor control lever a little, then
press On-Line once to record another waveform. Now change the
color of Y1 again. Move the resistance control again and press On-
Line once. Change the Y1 color, adjust the resistance and press
On-Line. Change the Y1 color, adjust the resistance and press On-
Line. Do this several more times if you like. Note that at some
resistance settings there may be no waveform to trigger on, move
the resistance control until it does.
Now your display should look something like this:
Storage mode
Now you see the range of waveforms this circuit can create, all at
the same time. Engineers often do this to compare signals during
analysis.
You can use Wait mode and different colors like this on the other
circuits if you like.
Now turn off storage mode and turn on FFT mode to look at the
frequency spectrum, try the settings shown here. Wait mode does
not apply in FFT mode, so it has no effect here.
Moving the
adjustable resistor lever will change the spectrum shown.
