Waveguide Band Specifications and Performance
3.1 ME7838A Millimeter-Wave VNA, Waveguide Bands
Three configurations are available for waveguide band operation for E and W bands when using the ME7838A system.
• First, the Anritsu 3743A Broadband Millimeter-Wave (mm-Wave) module can be adapted to waveguide measurements using waveguide
adapters.
• Second, the Anritsu 3744A-EE or 3744A-EW millimeter-wave module can be used. These version modules operate in the extended E and W
waveguide bands and are operational using the MS4644A, MS4645A, or MS4647A VectorStar (with options 08x and 007) and the 3739B
broadband/millimeter-wave test set.
• The third configuration option is to use external millimeter-wave modules with any model VectorStar (with options 08x and 007) and the
3739B test set. For millimeter bands above 110 GHz either the OML or VDI modules may be used.
