Return Procedure
In any correspondence or telephone conversations with Agilent Technologies,
please refer to the instrument by its model number (N5501A, for example) and
serial number. With this information, the customer engineer can determine
whether your instrument is still within its warranty period and provide
accurate shipping information.
Determining your instrument’s serial number
When Agilent Technologies manufactures an instrument, it is given a unique
serial number. This serial number appears on a label on the rear panel of the
instrument (see Figure 340). The serial number has two parts. The first part
makes up the prefix and consists of four digits and a letter. The second part
makes up the suffix and consists of the last five digits on the label. The serial
number prefix is the same for all identical instruments; it changes only if the
electrical or physical functionality differs between instruments. However, the
serial number suffix changes sequentially from instrument to instrument to
uniquely identify every one.
