Complete 99% Assembled and Tested Kit - Sorry, out of stock - Next Availability to be Confirmed
A new version of the VA5 Kit with only 1 component to solder - final assembly only takes 10-15 minutes before unit is ready to use.
Please note that the Complete VA5 Kit is still available.
The newly designed VA5 is a high precision 600 MHz instrument for measurements of antennas, cables
and other one port devices.
The 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 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.
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.
This FA-VA5 Kit is a 99% Assembled and Tested Kit including a pre-assembled PCB with pre-programmed microcontroller, graphic display including backlight, and a USB module, fitted in a specially designed enclosure.
Final assembly of the 99% FA-VA5 kit is easy and consists of:
- Fitting and soldering of only 1 component, the power On/Off slide switch to the main PCB, see fig. 3. of FA-VA5 Manual
- Fit main PCB in the bottom Enclosure and secure with 4 screws provided in the kit
- Plug in the ready assembled LCD/'Backlight Display unit into the Main PCB, see fig. 9. Remove any protective plastic cover
- Place the 3 knobs on top of the pushbutton switches on top of the main PCB - see fig. 9.
- Ensure that Slide switch is set to Off as in fig. 10. then fit 2 AA batteries (not supplied in the kit)
- Fit the Enclosure top cover, ensuring that all 3 push button knobs protrude outwards and secure with the 4 screws provided.
The kit also includes Short, Open and Load calibration elements, which are
usable up to about 100 MHz but require soldering of the BNC short connector.
A high-quality 3pc or 4pc calibration kit, covering a
frequency range up to 600 MHz, and with Load parameters individually measured, is also available from our Webshop.
