An new high precision 600 MHz instrument 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.
designer, Michael Knitter DG5MK, has taken feedback from users of the
previous VA4 instrument and incorporated many 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
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.
FA-VA5 Technical Datasheet
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 any 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 as a 3pc or 4pc set.
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:
Also available - High Quality Presentation Case for safe storage of VA5 plus Accessories.
FA-VA5 Kit including Japanese translation of assembly and operating instructions is also sold through SDR-Kits' Authorised Resellers for Japan: ICAS Enterprises www.ICAS.to
