Instruments Covered by Manual
Agilent Technologies uses a two-part, ten character serial number which is stamped on the
serial number plate (see Figure 1-1) attached to the rear panel. The rst ve letters are the
serial pre x and the last ve digits are the sux. The pre x is the same for all identical
instruments; it changes only when a change is made to the hardware of the E4915A/E4916A.
The sux, however, is assigned sequentially and is unique to each instrument. The contents of
this manual apply to instruments with the serial number pre xes listed under Serial Numbers
on the title page.
