Formatting Labels for Logic Analyzer Probes
When using a multi-card logic analyzer:
• When both analyzers are turned on, pods 1/2 and 3/4 of the master card
cannot be assigned to the same analyzer.
• Each pod pair has two clock channels, but only the clock channels of
pods on the master card can be used in the analyzer's clocking setup.
(The master card's pods needn't be assigned in order to use their clock
channels).
To turn on an analyzer that is off
1. Select Off and choose State or Timing.
(Only one analyzer at a time can be set to Timing.)
A second analyzer window appears after a pause for setup.
You can also turn on an analyzer that is off by opening the Workspace
window and dragging the instrument tool icon onto the workspace.

To set pod threshold voltages
The threshold voltage is the voltage level that a signal must cross
before the logic analyzer recognizes a change in logic levels. In addition
to a user defined choice, you can also select a predefined level from the
standard choices.
Standard
1. In the Format tab, select the threshold button located just below the pod
name.
2. In the Pod threshold dialog, choose one of the standard threshold options:
• TTL -- The threshold level is +1.50 volts.
• LVTTL -- The threshold level is +1.40 volts.
• SSTL2 -- The threshold level is +1.50 volts.
• SSTL3 -- The threshold level is +1.25 volts.
