N7020A and N7024A Power Rail Probes User’s Guide 45
Direct Connection using the N7022A Main Cable
This connection mechanism allows you to directly probe DUTs that are located up
to 1.2 meters from the probe thereby ensuring an easy connection to the target.
The N7022A main cable is flexible and durable while still providing high signal
fidelity.
The highest BW configuration for the N7024A Voltage Rail probe system is when
the user has a 50 ohm line from a voltage rail on their DUT to an RF connector and
this is connected to the N7022A coax and N7024A probe amp combination.
You can achieve the highest bandwidth configuration for the N7024A probe by
connecting the N7022A main cable to an RF connector that connects to the DUT’s
power rail on a 50
Ω
line.
NOTE
Once you have made the hardware connection using the appropriate probe connection
accessory (cables/browsers), ensure that the same hardware connection mechanism is
reflected in the oscilloscope’s Infiniium software GUI. You do this using the Probe
Configuration dialog box. This ensures that you get accurate measurements as per the
connection mechanism.
For instance, if you are using the N7022A main cable with the N7024A probe, then ensure that
the Probe Configuration dialog box has N7022A:N7024A Main Cable as the selected head in
the Probe Head section.
