The Tektronix DM5120 is a programmable 6½-digit multimeter plug-in for the TM5000 system.
The DM5520 is a standalone version, i.e. a DM5120 in a dedicated mainframe, which however cannot be used outside the DM5520 frame.

Internals
The DM5120 shares its analog section design with the Keithley 196, minus the front/rear switch.
The instrument's internal voltage reference is based on the LM399.
