1.2 Minimum Requirements
The SM2060 series of system DMM’s are precision plug-in modules that are compatible with IBM type personal
computers (PCs), PXI and cPCI chassis. It requires as a minimum a Pentiums computer. They require a half-length
expansion slot on the PCI bus or 3U PXI slot. A mouse must be installed when controlling the DMM from the
Windows Control Panel. The SM2060 comes with a Windows' DLL, for operation with Windows' Version
95/98/Me/2000/XP and NT4.0.
1.3 Feature Set
The base unit, the SM2060, has traditional 7-1/2 digit features and it can be used as a general purpose DMM, where
accuracy and speed are important. The High Workload Multi Function SM2064 adds timing, capacitance,
inductance, sourcing and a lot more speed. With its specialized measurements, it can replace some costly
instruments, shrinking the size and cost of a test system.
