N-Connector version of the new VNWA3SE Automatic 2 Port VNA

The VNWA 3SE N connector version is a full 2-Port version of the VNWA 3 and compliments the VNWA 3SE SMA version.

Inclusion of a solid-state 2-Port switch eliminates the need for manual reversal of the Device under Test (DUT) allowing forward and reverse measurements to be taken with a single key click.  Fitted with 2 USB Codecs, S11, S21 or S12 and S22 measurements are made in a single sweep.

The 2-Port VNWA3SE N is fitted with quality Amphenol N connectors and comes in a solid 2mm anodized enclosure but at twice the depth of the existing VNWA enclosure hence offering improved mechanical stability.

N Connector Calibration Kits To support accurate calibration of the VNWA3SE N version a range of N-Connector Calibration Kits are available.

Upgrade Kits: VNWA 3E/3EC owners can upgrade their VNWA to the VNWA 3SE 2 Port N or SMA Version using an Upgrade Kit.
