Introducing the DG8SAQ VNWA 3 Low Cost 1.3 GHz Vector Network Analyzer

Covering 1 kHz to 1.3 GHz and powered from a PC USB-bus, the VNWA 3 Series offers a dynamic range of 90dB up to 100 MHz, better than 70dB to 500 Mhz and better than 50dB above 500 MHz.   Measures up to 65000 datapoints with sampling time from 0.13 mS to 100mS  - maximum sweep duration 30sec.

Designed by Professor Thomas Baier DG8SAQ, the VNWA 3 Series is used by Professionals, Universities, Research Institutes and Radio Amateurs worldwide since its launch in 2009.

VNWA Driver and Software runs on all recent Windows 64 bit and 32 bit Operating Systems, including Windows 11, 10, 8.1 & 8, Windows 7 and Windows Vista. Software is free to download and updated regularly by the designer.

The DG8SAQ VNWA 3 Series offers:

• All VNWA hardware on a single Printed Circuit board for maximum reliability

• High stability 12 MHz +/- 0.5 ppm Analogue TCXO from which all clock signals are obtained

• Redesigned Solid 2mm Anodized enclosure and brass chassis

• S-parameter, S11, S12, S21, S22, VSWR, Smith Chart & Component values

• Time Domain - Distance to Fault Measurements - Network Matching tool

• Supplied fully assembled and tested
  

The DG8SAQ Network Analyzer is available as 3 different models - VNWA 3, VNWA 3EC and the VNWA 3SE - all offering the same accuracy, measurements and range.

The VNWA 3 is a great value, entry level device.

The VNWA 3EC is factory fitted with an Expansion board and external clock connection and offers the following additional benefits over the VNWA 3:

• Simultaneous S11 and S21 measurements in one Sweep

• RJ12 socket to provide external VNWA control and VNWA power connectivity

• Reduced Power consumption - DDS switched mode supply

• External VNWA 3 Clock connectivity

• VNWA Reference Clock output: TCXO 12 MHz*x (where x=2 3 4 5 ...8) stability  +/- 0.5 ppm Output 1 kOhm impedance, 150mVpp

• External Reference Clock input: Recommended external clock: 36 MHz with  a level of between -6dBm...+3dBm / 50 Ohms

The VNWA 3SE Automatic 2 Port Model

Due to popular demand, SDR Kits have developed the VNWA 3SE - a fully automatic 2-Port VNA.

• Whilst maintaining the dynamic range and specification of the original design, the VNWA 3SE also features a Solid-State 2-Port switch which eliminates the need for manual reversal of Device under Test (DUT), allowing forward and reverse S11, S12, S21 and S22 measurements to be taken with a single key click.

• The 2-Port 3SE comes as standard with SMA Connectors but N-Connector and BNC Connector models are also available. All models use the same solid 2mm anodized enclosure, but at twice the depth of the existing VNWA enclosure which offers improved stability.

• The Magi-Cal® Automatic Calibrator is fully compatible with the VNWA 3SE SMA Version, and is sold as an optional extra.

• Retrofit Upgrade Kits for exisiting VNWA 3 or VNWA 3E/3EC owners are also available, keeping the investment in their VNWA up to date.
