M Modules are ANSI/VITA 12-1996 standard mezzanine cards which afford the user significant benefits and flexibility when configuring a test, data acquisition or control system. Among these benefits are:
  • Standard is controlled by an industry organization and not a single vendor
  • Over 100 M Modules are currently available from a number of vendors (Product Directory)
  • Once an instrument or function is selected it may be ported to a variety of backplanes or busses gaining the user platform independence.
  • The simple interface bus makes for easy development of custom functions without the cost of developing VXI, PXI, LXI modules. Just buy the appropriate carrier.
  • Instrument vendor development costs are reduced ( 1 Pulse Gen works in VXI, LXI, PXI), thereby offering the potential for reducing customer's life cycle costs.
  • Provides for multiple functions in a single VXI, PXI, VME slot.
  • Can provide for hardware traceability between larger VXI factory test sets and smaller PXI or LXI field test sets.


Founded in 1984, C&H Technologies, Inc. started as a design service company and gradually migrated to the ATE service business picking up a license in 1987 to support a Texas Instruments product line. In 1999 the company moved into its new custom designed 15,000 sq. ft. facility in Round Rock, TX.

The company has invested heavily in a growing line of test and measurement instruments to support its customer base.

  • In early 2003 the company started shipping its first Power PC based products.
  • At present C&H has nearly 100 products in VXI, PXI, IP, M Module, Ethernet and LXI.
  • Emphasis has been on sources and carriers so as to allow the company to provide platform independent instruments.
  • Custom Designs are facilitated by using intelligent carriers and M Modules.
