Channel Groupings
The 18 channels in the lead set are divided into two physical groups of 9 and each group is
bundled with a plastic separator. When using 36 channels there are 4 groups of 9 leads
Note
: The grouping you assign to the digital lines in the software interface can be different than the physical grouping of
digital lines. The physical grouping is intended for easy identification of all 18 digital lines.
Connector Colors
The wires in each color group use 9 repeating colors.
The color sequence corresponds to the resistor color code making it easier to know the digital line
number without having to look at the label.
Standard Output Connection
The standard terminations on the digital lead sets can be pushed directly onto 25-mil pins.
MicroGrippers or NanoGrippers
may also be
used to probe the test circuit’s pins. LeCroy provides
a selection of small, medium, and large grippers for various pitch sizes. A more complete
selection of adapter probes is available for most chips from Emulation Technology Inc., Yamaichi
Inc., and other manufacturers
.
Threshold Levels
The threshold level determines how the input signal is interpreted. The threshold level can be set
in either the Digital Grouping Setup or Pattern Trigger Setup dialogs (it is the same setup, but is in
two different places for operator convenience).
