10 VM2710A Introduction
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.

VM2710A Introduction 11
Regardless of whether the VM2710A is configured with other VM2710A modules or with
other VMIP modules, each DMM is treated as an independent instrument in the VXIbus
chassis. Each has its own Unique Logical Address and, as such, its own front panel FAIL and
ACCESS indicators.
DESCRIPTION
The VM2710A is designed for fast system throughput with greater than 2000 readings/s across
the backplane. For applications that require multiple input monitoring, the VM2710A provides
for on-board limit checking and the option of generating VXIbus triggers if the input exceeds
these limits. This approach further speeds system throughput by freeing up the VXIbus
controller and backplane from having to continuously monitor these limits.
As part of the VMIP family of instruments, the VM2710A can be combined with up to two
other modules to form a high-density VXIbus instrument that fully utilizes the capabilities of
the VMIP module.
Two differential isolated input channels are provided on the VM2710A to allow one channel to
be connected to a scanning multiplexer while the other can be brought directly out for manual
testing or precision measurements.
Measurement aperture times may be programmed allowing the choice of resolution, accuracy,
and noise rejection (i.e., rejection of 50 Hz or 60 Hz noise). Fast function/range changes allow
for optimum measurement throughput. Short aperture times give high-speed readings while
longer aperture times give greater accuracy.
The DMM has extensive triggering capabilities including programmable delays to allow
synchronization with external devices. It can be triggered from the front panel trigger input, the
VXIbus trigger lines or via word-serial protocol.
The VM2710A is programmed using message-based, word serial protocol. The commands are
SCPI and IEEE STD 488.2 compatible. VXIplug&play drivers are also provided to further
ease programming.
The calibration constants are stored in non-volatile memory and are password protected for
security. These constants are determined when the instrument is calibrated and can be changed
as necessary (such as during routine calibration cycles). These constants may also be examined
at any time via a word serial query and altered via a word serial command. All calibration is
done via software, including the ac range. This allows for automated calibration and eliminates
the need for removing covers from the unit.

32-wire accuracy is the same as that shown for 4-wire measurements after performing a math null measurement. Without setting the null, readings will
include lead resistance, which is application specific, and add 0.2 Ωof additional error for contact resistance. Typical 24 AWG stranded wire is
0.03 Ω/ft.
