Make sure you have installed the
Soundcard Scope Version 1.46 on
your computer ( www.zeitnitz.eu/
scope_en; click on scope 1.46) and
then open it. Next, connect the
desired scope probes to the inputs
of the PC two-channel o-scope.
I connected the probes to my
homebrew function generator
(Figure 11A). Turn on the PC o-scope
and the function generator. Adjust
the function generator to 1,000 Hz,
set the PC o-scope channel 1 and
channel 2 input selector switches to
the 2V-X.1 position. On your
computer oscilloscope display
(Figure 11C), set the amplitude CH1
to 100 mV/Div, click the sync box
between CH1 and CH2, set the
Time/Div to 2 mSec/Div, and set the
trigger to auto, rising, channel 1,
threshold = 120m. The screen should
appear as seen in Figure 12.
If you click on the settings tab,
then on the save settings button, you
can save the Soundcard Scope
settings as an .XML file to easily
restore them for future use. Give
them a name related to the task that
they were used to perform; for
example, Fnctn Gen 1.
