Elenco PK101 w/ Computer Interface - Manual (Page 8)

Click on the On-Line button if Winscope is currently in Hold mode and you should get a picture simi-
lar to this one:
The waveform peak is off the top of the screen because the scope gain (amplification) is set too
high. You may adjust this gain by moving the Y1 gain control around (try it).
Similarly, you may adjust the position of the waveform on the screen by moving the Y1 position con-
trol around (try it).
Now click on the 1:1 button to set the gain to x1 and disable the Y1 controls. You should now have a
picture similar to this one:
Note that your picture may not
exactly match this picture due to
variances in the microphone input
gain between computers, which is
beyond software control. You may
want to adjust the volume control
of your microphone input to com-
pensate, see note A on page 6
for more details. You may also dis-
able 1:1 mode by clicking on its
button again and then adjust the
gain using the Y1 control.
The gain and position control features just described enable electronics engineers and technicians
to “see” the amplitude (voltage level) of a signal. By adjusting the settings on an oscilloscope, they
can look at both very large and very small voltage waveforms.
