a. In March 2013, Keysight discontinued using a display with florescent tube backlighting, and began using a display with LED
backlighting. Associated parts are indicated in this table with either “Tube” or “LED.” If you replace an old part number <des-
ignated “Tube”> with its new part number <designated “LED”>, you must also replace ALL of the other old part numbers
<designated “Tube”> in the table with their new part numbers <designated “LED”>.
