Receiving the System
The N5261A and N5262A millimeter head controllers and the test head 
modules are sensitive to electrostatic discharge (ESD). Ground your work 
station before unpacking and installing the test head modules. See 
“Electrostatic Discharge Protection” on page 1-4.
The System as Shipped
The N5251A system components will arrive packaged separately. For a complete list of 
components shipped with your system, refer to Table 3-1 on page 3-3 and Table 3-2 on page 3-4.
When the entire shipment has arrived, contact Keysight Technologies to arrange for system 
installation. See “Keysight Support, Services, and Assistance” on page 5-4.
Keep the shipping containers until the system checklist has been completed, and the system has 
been checked for physical damage. 
If the shipping container is damaged or the packaging material shows signs of stress, notify the 
carrier as well as Keysight Technologies. Keep the shipping materials for the carrier’s inspection. 
Keysight Technologies will arrange for repair or replacement of damaged equipment without 
waiting for a claim settlement from the carrier. Refer to “Keysight Support, Services, and 
Assistance” on page 5-4.
