Measurement module of virtual vector network analyzer

A hand-carriable, single port measurement module of a virtual vector network analyzer that is sized and configured so as to be directly connectable to devices typically located within confined spaces normally requiring the use of an intervening test cable and which are closely spaced to other devices that need to be tested by other measurement modules, wherein the measurement module comprises:

• a single test port extending from one end of an elongated housing, the housing containing a circuit that is configured to:
• transmit and receive test signals through the test port for measurement of a device under test;
• and
• transmit digitized signals representing the test signals through a communication interface of the measurement module to a user interface that is separate from the housing for presentation to a user;
• wherein the housing defines a first dimension along an axis of insertion of the test port and second and third dimensions that are each transverse to the axis of insertion;
• wherein the first dimension is substantially less than 12 inches;
• wherein the second and third dimensions are each substantially less than the first dimension;
• and
• wherein the length of a perimeter of the housing substantially formed by the second and third dimensions is substantially less than 12 inches;
• whereby the dimensions of the housing allow the measurement module to fit comfortably in a user's hand and be directly connected to a typical device under test without the need for an intervening test cable.
