As a result of the frequency measurement, the status monitor thus shows one of the following
frequencies [Hz]:

Error Frequency
A “ frequency ” err or will be indicated, if a frequency has been selected (not “Auto”) and
there is a difference of measured and selected frequency, or if “Auto” has been selected
and the measured frequency does not comply with a valid word clock frequency. This
check will be done permanently. Any Pull-Up or Pull-Down frequency will be converted
to the basic frequency; the check thus compares the basic frequency and factor only. The
cause of this error may be a faulty configuration of the signal source.
This error will be classified as a major error, so this error will be considered for a
changeover.
The status monitor indicates these measurements and errors at
Input 1 page or Input 2
page resp.
Error Word Clock Frequency Difference
Signals within a pair should have the same frequency. In this case, even the Pull-Up and
Pull-Down frequencies are considered. SW permanently checks the signals for
differences. In case of differences, a “ word clock frequency difference ” error will be
indicated. The cause of this error may be a faulty configuration or synchronization of the
signal source.
This error can be assigned to a signal pair only, so this error will not be considered for a
changeover.
The status monitor indicates this error at the
System page.
