Preparing the Oscilloscope for Use
To use the digital probes (mixed-signal oscilloscope only)
To use the digital probes (mixed-signal oscilloscope
only)
1 If you feel it’s necessary, turn off the power supply to the circuit under
test.
Turning off power to the circuit 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 D15 - D0 connector on the front panel
of the mixed-signal oscilloscope. The digital probe cable is indexed so
you can connect it only one way. You do not need to power-off the
oscilloscope.
Use only the Agilent part number 54620-68701 digital probe kit supplied with
the mixed-signal oscilloscope.
