2.5 Tips
Select the right timescale
·
Digital oscilloscopes sample the input signal at configurable rates. (The PropScope
samples up to 25 Million times/second) Sampling a signal too slowly will yield artifacts-
so always look at a new signal with a faster timescale first.
Use a trigger
·
Click the Trigger tab to configure a trigger to stabile the signal. You can adjust the
horizontal slider on top of the graph to show data before or after the trigger fired
Use AC/DC mode
·
If you
¶
re not interested in the DC offset of your signal, switch to AC coupling.
Make sure the probe
¶
s 1X/10X switch is correct
·
Your PropScope comes with two 1X/10X probes. Switch the probe to 10X and select
10X in the

dialog of the PropScope software to measure larger signals.
Several Features depend on the DAC/LSA Card
·
To use the Function Generator, Logic Analyzer, and External Trigger you need to plug
the DAC/LSA Card into the PropScope before you start the PropScope software. You
can only use one of these features at a time: Channel 2 Input, Logic Analyzer, Function
Generator. The PropScope software will manage this for you based on your selections.
Ie, when you turn on the Function Generator, Channel 2 will be turned off, and vice versa.
