1.4.5 Logic-Analyzer
The module „Logic-Analyzer“ shows 16 digital channels with a fre-
quency of up to 50 kHz. Image frequencies measured above this
limit do not exist in reality. This should be kept in mind when defin-
ing a completely unknown signal. In case of doubt, an observation
through the oscilloscope may shed light but only up to a frequency
of 500 kHz.
All digital channels use a common time basis.
In the „Logic-Analyzer“ mode, the channels D16 to D22 are re-
served for special functions on the pins 19 to 25. If required, they
are configured as output and therefore shouldn’t be connected.
The levels of the signals must meet the requirements of the 5 V
CMOS. In case they don’t, you need to connect a level converter.
