MMVNA-200 Twisted Pair Cables Tester



Mixed Mode Multi-Port VNA (MMVNA) is a portable vector network analyzer that is purpose-built for characterizing twisted pair and coax cables and components. Balanced transmission is finding increasing adoption. MMVNA is a user friendly, versatile analyzer that is most often deployed in manufacturing and lab tests of IoT applications, specialty sensor connections and automotive wiring harness testing.

In a matter of seconds, the MMVNA can measure 256 different S-parameter combinations in a single measurement sweep. The VNA Manager software provides an easy way to configure required S-parameters and arrange them in convenient views and reports. MMVNA is IP addressable, so you can ensure uniform testing methodology across distributed locations with remote configuration capability.

MMVNA-200 – Twisted Pair Cables Tester

Raw Cable Test Fixture with MMVNA


Compact and extensible–8-port form-factor extensible to higher port densities in multiples of 8. Primarily used in laboratory and manufacturing environments for the automotive wiring harness and telecommunications cable testing.

4x Differential Measurement Ports–Each port features its own transmitter and receiver, enabling fast, concurrent measurements on all ports. For applications such as harness testing, this means a considerable saving of table space and test time.

Scalable Measurement System–The VNA Manager software can control and collect data from multiple MMVNA units and make uniform presentations. This is particularly helpful in testing complex multi-wire harnesses with a single measurement command.

Remote management–The MMVNA is IP addressable enabling remote management and data acquisition for inline manufacturing testing.

Test configurations–DUT endpoints are not required to connect to a common test interface. The 16-port option is deployed as two 8-port devices that communicate over the DUT rather than a fixed backplane enabling assembly and cable testing where ends are spatially separated.

Standards Compliant–Adheres to Open Alliance, BroadR-Reach, 802.3bw, 802.3bp and 802.3ch (draft) for the following s-parameter tests:

  • Link segments and components; cables, connectors, and wire harnesses
  • Open Alliance VNA Reference Measurements
  • Equipment connector interfaces (ECU, MDI)
  • Transmitters and Receivers


VNA Manager–The companion VNA Manager is the control software for the MMVNA settings of all S-Parameters, test initiation and saving of test data. Touchstone and comma separated variable (csv) measurement data output format.
