VM4016 Preparation for Use 

11 

 
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.
