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 278).
