Hi Bryan,
> I'm rather new to oscilloscopes and I was wondering should I expect
it to be able to tell me the frequency of a slow-moving CV. I'm not
seeing a way to read the frequency of a wave.
As long as your slow-moving CV is actually repetitive, then you
should be able to do it by measuring the time it takes for the
pattern to repeat. I don't know what facilities that scope has, but
often scopes have cursors you can move around the screen, and it will
tell you the readings of where they are, and then take the
difference. If not, then you will have to judge it for yourself, from
the timebase setting of 'so many seconds per division'. Do this at
two points where the pattern repeats, for example the peaks, or where
the wavefrom crosses the zero line *in the same direction*: this is
called the 'period' of the signal. Then simply divide this into 1 to
get the frequency, so frequency = 1/period.
Try it on something you know first, to check that you have the hang
of it, for example, for middle C coming out of one of your
oscillators you should see the time difference as about 0.0038
seconds = 3.8 milliseconds, so 1/0.0038 = 263Hz (middle C actually
261.63Hz). For a slow moving waveform it is likely that you will have
to 'freeze' the display after one pass to be able to make a
measurement if the timebase is set very slow.
