Demultiplex
The Demultiplex mode is used to store two different sets of data that
occur at different times on the same channels. In Demultiplex mode
both the master and slave clocks are used, but only one pod of the pod
pair is sampled.
Channel assignments are displayed as Demux Master and Demux
Slave. For easy recognition of the two sets of data, assign slave and
master data to separate labels.
When the analyzer sees a match between the slave clock input and the
Slave Clock arrangement, Demux Slave data is latched. Then, followed
by a match of the master clock and the master clock arrangement, the
slave data is strobed into analyzer memory along with the master data.
If multiple slave clocks occur between master clocks, only the most
recently latched data is strobed into analyzer memory.
