DIGITAL TRACE GROUP SETUP
Digital trace groups are very similar to analog channels
– they can be turned ON or OFF, they can
be increased in size, and they can be positioned on the grid. You can also store them as
waveform files. In software, they are accessed through the same Vertical dialog as analog
channels. Cursors and most timing measurements also work with Digital traces.
Notable differences include the lack of sampling information in the trace data and the lack of
dedicated front panel controls (though some front panel controls double as position and size
controls when the Digital trace group is active).
However, Digital trace groups have capability far beyond that of an analog channel. Each Digital
trace group can consist of 1-36 digital lines. You can create up to four Digital trace groups, and
each digital line can be used in as many or as few groups as desired. You can choose to display
the group of digital lines as individ
ual digital traces (one per line), or as a “collapsed” bus with bus
data values calculated on screen within the bus trace. Since there are so many digital lines,
Digital lines or buses can be renamed so that it is easier to keep track of the multitude of digital
signals on the screen.
