VM4016 Preparation for Use 11
SECTION 1
INTRODUCTION
INTRODUCTION
The VM4016 is a high-performance Analog Comparator module which has been designed to
monitor analog signals and cause VXIbus interrupts to occur when programmed input limits have
been exceeded. The instrument uses the message-based word serial interface for programming
and data movement, as well as supporting direct register access for very high-speed data retrieval.
The VM4016 command set conforms with the SCPI standard for consistency and ease of
programming.
The VM4016 is a member of the VXI Technology VMIP™ (VXI Modular Instrumentation
Platform) family and is available as a 16-, 32- or 48-channel, single-wide VXIbus instrument. In
addition to these three standard configurations, the VM4016 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 VM4016 with
two other instrument functions in a single-wide C-size VXIbus module. Figure 1-2 shows the
48-channel version of the VM4016. The 32-channel version would not have J200 and its
associated LEDs and nomenclature while the 16-channel version would also eliminate J202.
