The 4708 incorporates a reference module which maintains a high accuracy specifiation ove the ambient temperature range of 23 to ±10°C.  A high level of stability is achieved by use of super-selected reference components and ultra-stable gain-defining resistors.  The "Autocal" feature ensures that its 24 hour specifications are usable; not merely figures of merit.

The 4708 uses a microprocessor for control management, simplifying it's use in complex manual operations, such as calibration of high quality multimeters.  The IEEE-488 (GPIB) interface provides a comprehensive remote programming capability, allowing programmed calibration of the 4708 itself.
