CONSTRUCTION
& RESULTS
I
put all of the components on the front panel and
connected it to the MCB2130 evaluation board with
a flat ribbon cable. I modified the evaluation
board by soldering an additional connector on
the P0 empty position, and I used two metal corners
instead of the plastic holders in order to have
a mechanical junction with the front panel (see
Photo 1a).

board to the front panel. b—The triangular
cursor on the left side corresponds to the
position of the Trigger Level knob on the
front panel. |
I
can observe audio signals (or other signals) with
a fine resolution (see Photo 1b). Of course, some
additional functions (e.g., different trigger
modes, a hardware input voltage divider (volt/div
control), signal processing, and communication
with PC) would be useful. I’ll definitely consider
adding these functions when I’m working on new
applications (spectrum analyzers, EKG scopes,
polygraphs, video games, and so on). As an example,
you can press the F button to call the menu with
reserved functions where the simplest screensaver
is only implemented.
