8. FREQUENCY MEASURING
A utility for measuring frequency on up to 4 inputs is provided as part of the
ASIX SIGMA&OMEGA APPLICATION PACKAGE software package. Filtering and
averaging can be selected for each measured input individually.
Please note, that the frequency measuring software and ASIX SIGMA&OMEGA
LOGIC ANALYZERS software cannot be used simultaneously, an exclusive
access to SIGMA2 is required.
