1.4.6 Digital Data-Logger
The module „Digital Data logger“ shows 16 digital measurement
channels with a frequency of up to 50 kHz. Image frequencies
measured above this limit do not exist in reality. This should be
kept in mind when defining a completely unknown signal. In case of
doubt, an observation with the oscilloscope may shed light but only
up to a frequency of 500 kHz.
All digital channels use a common time base.
In the „Digital Data logger“ mode, the channels D16 to D22 are
reserved for special functions on the pins 19 to 25. If required,
they are configured as output and therefore shouldn’t be con-
nected.
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.
