SECTION 1
INTRODUCTION
INTRODUCTION
The VM2710A is a high-performance, autoranging 6.5digit multimeter. It offers dc and ac
voltage, dc and ac current, and 2- and 4-wire resistance measurements in a very small footprint.
The instrument uses the message-based word serial interface for programming and data movement,
as well as supporting register data access for high-speed data access. The VM2710A command set
conforms to the SCPI standard for consistency and ease of programming.
The VM2710A is a member of the VXI Technology VMIP(VXI Modular Instrumentation
Platform) family. This gives the user the added flexibility of combining it with other instruments,
such as arbitrary waveform generators or digitizers, to create a multi-function C-size card. Finally,
users do not need to take up a complete VXIbus card slot for the DMM functionality required,
making the VM2710A the ideal choice for data acquisition and ATE. The VM2710A may be
combined with any of the other members of the VMIP family to form a customized and highly
integrated instrument (see Figure 1-1). This allows the user to reduce system size and cost by
combining the VM2710A with two other instrument functions in a single-wide C-size VXIbus
module.
