Giga-tronics ASCOR offers a family of products to support Tektronix VXI users with a true drop-in replacement with full software and hardware compatibility for Tektronix VXI module. We are the only company able to offer you form-fit-function built on superior design architecture. There are no special cables or adapters required. Our Tektronix Replacement cards offer:

  •  Register-based VXI versions which use Plug&Play Software Drivers
  • Message-based VXI versions (MPU Internal) which respond to standard SCPI commands
  • Identical Front Panel Connectors, with the same signal on the same pin as the Tektronix module
  • Giga-tronics ASCOR Superior Design Architecture results in identical or improved specifications over the original Tektronix specifications
