2. Turn the Pan knob to place the center of
the zoom box close to w here the relay

3. Turn the Zoom
knob to magnify the
waveform in the zoom window.
The ragged waveform and the inductive load
in the circuit suggest that the relay contact
may be arcin

Correlating Data with a TLA Logic Analyzer
To troub
leshoot designs with fast clock edges and data rates, it helps to view analog characteristics of d igital 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 analyzer display. You can then view time-correlated analog and digital signals side by-side, and use
this to
pinpoint sources of glitches and other problems.
The iVi
ew External Oscilloscope Cable Kit allows you to connect y our logic analyzer to a Tektronix oscilloscope. This
enables communication between the two instruments. The Add External Oscilloscope wizard, w hich is available from
the TLA application System menu, guides you through the process of connecting the iView cable between your logic
analy
zer and oscilloscope.
The TL
A also provides a setup window to assist you in verifying, changing, and testing the oscilloscope settings. B efore
acquiring and displaying a waveform, you must establish a connection between your Tektronix logic analyzer and
oscilloscope using the Add External Oscilloscope wizard.
