Introducing the new high precision 600 MHz Antenna Analyzer for measurements of antennas, cables and other one port devices.
The new VA5 is a portable, full-featured Vector Measuring Device with a frequency range of 10 kHz to 600 MHz, with the added benefit of a USB port for connection to a computer.
The designer, Michael Knitter DG5MK, has taken feedback from users of the previous VA4 instrument and incorporated many of the requested new features in the VA5, whilst maintaining high performance and excellent value for money.
- Frequency Range 10 kHz – 600 MHz
- Small dimensions 15 x 8.5 x 2.2 cm – fully portable
- User friendly – intuitive menus
- Large display with good readability
- Low power consumption (up to 40 hours from 2 AA batteries)
- SOL Calibration function
- USB-interface with support of the DG8SAQ VNWA Software
- Real time clock with backup capacitor
- Audible buzzer alert for minimum SWR alignment
The FA-VA5’s graphic display shows the complex impedance, standing wave ratio, complex reflection coefficient, capacitance and inductance.
Vectorial measurement means that, unlike a scalar instrument, not only the SWR is measured and displayed, but also the value of the impedance, including the signed imaginary part. The so-called SOL (Short, Open and Load) compensation is used for the calibration of the device and provides precise measurements in different configurations.
New Feature – USB-interface
The new USB-interface allows follow-on processing of measurement data, a feature that was top of the wish list for many Radio Amateurs. Michael has collaborated with Dr. Thomas Baier, DG8SAQ, to introduce support for the VA5 in his well-respected DG8SAQ VNWA software application. The combination of FA-VA5 and VNWA Software will allow all kinds of one port measurements included in the software. One example is Time Domain Reflectometry (TDR) to help find defects in antenna installations. Ths USB-interface also enables the user to carry out future firmware updates to the VA5.
Complete Self-Assembly Kit
The FA-VA5 is sold as a complete kit including a pre-assembled PCB with pre-programmed microcontroller, graphic display including backlight, and a USB module, fitted in a specially designed enclosure.
The kit also includes Short, Open and Load calibration elements, which are usable up to about 100 MHz. A high-quality calibration kit, covering a frequency range up to 600 MHz, and with Load parameters individually measured, is also available from our Webshop.
Final assembly of the kit is considered to be of medium difficulty and consists of fitting and soldering just 12 through-hole components which should take under 3 hours. Download the manual which shows clear and straightforward assembly instructions, and demonstrates the quality of measurements displayed:
Please note that we are awaiting delivery of the Assembly and Operating Manuals, due by 10th July. VA5 orders will be shipped once Manuals are received. If you are happy to download the Manual please state this at time of order, and we will ship without delay.
