Time - Horizontal Scale (X-axis)
The TIME parameter (top of the screen, accessed via button
2-4) shows the scope’s current horizontal resolution in
microseconds, milliseconds, or seconds per division. On the
grid there are 12 divisions on the X-axis (the grid is 12 boxes
wide). For example, if the TIME parameter is set to 1MS
(one millisecond), then the scope is showing a total of 12
milliseconds of signal across the display.
The TIME parameter ranges from 50uS (50 microseconds)
to 5.0S (ve seconds), allowing for a minimum total display
of 600 microseconds and a maximum total display of 60
seconds.
Let’s look at an example of viewing a LFO waveform. The incoming LFO signal is a sawtooth wave with a frequency of 0.1Hz,
which is equal to a period of 10 seconds (1Hz frequency = 1 second period); it’s a fairly slow LFO. But let’s say we didn’t
know the LFO’s frequency or period; we can use the scope’s horizontal scale to measure it (or alternately, the scope’s cursor,
covered in the following pages).
The TIME parameter is set to 5.0S (ve seconds), so each vertical grey line is equal to 5 seconds of time. You can see on the
scope’s grid that the waveform crosses two of the vertical grey lines before repeating, so from this we can tell that the LFO’s
period is 10 seconds.
Also, there are 6 full cylces of the saw wave across the scope’s display. With 10 seconds per cycle this demonstrates that
there are 60 seconds of time displayed when the TIME parameter is set to 5.0S.
