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, which has been available since June 2020.

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 comes 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.

VNWA 3SE N Options

The VNWA3SE N  version will be supplied with USB-Cable only.   Additional items such as N Calibration Kits, test leads or a presentation case will be available as options depending on Customer requirements.

N Connector Calibration Kits To support accurate calibration of the VNWA3SE N versions, SDR-Kits is offering  two types of N Calibration Kits.
Both kits come with individually measured Load between 0 and 1300 MHz with a printout of the measured characteristics which includes a link to download the VNWA calibration files (.ckf files) 

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