106 Agilent InfiniiVision 3000 X-Series Oscilloscopes User's Guide
6 Digital Channels
Turning off power to the device under test would only prevent damage
that might occur if you accidentally short two lines together while
connecting probes. You can leave the oscilloscope powered on because
no voltage appears at the probes.
2 Connect the digital probe cable to the DIGITAL Dn - D0 connector on
the front panel of the mixed- signal oscilloscope. The digital probe cable
is keyed so you can connect it only one way. You do not need to
power-off the oscilloscope.
3 Connect the ground lead on each set of channels (each pod), using a
probe grabber. The ground lead improves signal fidelity to the
oscilloscope, ensuring accurate measurements.
Probe cable for digital channels
Use only the Agilent logic probe and accessory kit supplied with the mixed-signal
oscilloscope (see "Accessories Available" on page 338).
