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, fan-less, mainframe based on the TM503B.

Resolution	±3,029,999 counts (6½ digits) in DC Volts and Ohms, 5½ digits otherwise in fast mode
Voltage ranges	300 mV to 300 V in decade steps, DC or AC
Input Impedance (DC Volts)	300 mV, 3 V: >1 GΩ 30 V: 11 MΩ 300 V: 10.1 MΩ
Input Impedance (AC Volts)	1 MΩ // 120 pF
Current ranges	300 μA to 3 A in decade steps, DC or AC
Resistance ranges	300 Ω to 300 MΩ in decade steps, 4-wire mode available in 300 Ω to 30 kΩ ranges
Features	True RMS measurement (crest factor ≤3:1) Calibration may be done manually through the front panel or via the GPIB interface.

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.
