The VM1548C is a high-performance I/O module that has been designed for high data throughput
and flexibility of configuration. The instrument uses the message-based word serial interface for
programming and data movement as well as allowing direct register access for very high-speed
data input and retrieval. The VM1548C command set conforms to the SCPI standard for
consistency and ease of programming.
The VM1548C is a member of the VXI Technology VMIP
™
(
VXI Modular Instrumentation
Platform
) family and is available as a 48-, 96-, or 144-channel, singlewide VXIbus instrument.
Figure 1-1 and Figure 1-2 show the 144-channel version of the VM1548C. The 96-channel
version would not have J200 and its associated LED’s and nomenclature while the 48-channel
version would eliminate J202 as well. In addition to these three standard configurations, the
VM1548C 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 VM1548C with two other instrument functions in a single
wide, C-size VXIbus module.
