Correlating Data with a TLA5000 Logic Analyzer
To troubleshoot designs with fast clock edges and data rates, it helps to view analog characteristics of digital signals in relation to
complex digital events in the circuit. You can do that with iView, which lets you transfer analog waveforms from the oscilloscope
to the logic an alyzer display. You can then view t ime-correlated analog and digital signals s ide-by-side, and use this to pinpo int
sources of glitches and other problems.
NOTE. Digital waveforms from 4000 Series oscilloscopes canno t be transferred to the logic analyzer display.
The iView External Oscilloscope Cable allows you to co nnect your logic analyzer to a Tektronix oscilloscope. This e nables
communication between the two instruments. F or 4000 Series oscilloscopes, you also need a TEK-USB-488 adaptor. The Add
External Oscilloscope wizard, which is available from the TLA application System menu, guides you throu gh the process of
connecting the iView cable betwee n your logic analyzer and oscilloscope.
The TLA also provides a setup window to assist you in verifying, changing, a nd testing the oscilloscope settings. Before acquiring
and displaying a waveform, you must establish a connection between your Tektronix logic analyzer an d oscilloscope using the
Add External Oscilloscope wizard.
