Year of Manufacture
You can determine the year the oscilloscope was manufactured by examining the serial
number label that is affixed to the rear panel of the oscilloscope. The serial number is
composed of two parts. The first part contains two letters and two numbers that signify
the oscilloscope’s county of origin and year date code. A year date code of “05” indicates
that the oscilloscope was manufactured in 2005. The second part of the serial number
contains a rolling number that is different for each oscilloscope.
