Handle your FX700 with care. It may be damaged if dropped,
burnt, punctured or broken, or if it comes into contact with
liquids. Do not use FX700 if it has been damaged.
Repairs. Do not open FX700 and try to repair by yourself. Disassembly may
damage the device or cause you injury.
Battery. Do not try to replace the FX700 battery yourself because you may damage it,
or could cause overheating and damage. The lithium-ion batteries must be re- cycled
or disposed of separately from household waste. Do not incinerate the battery or
exceed the recharge time of 6 hours.
Do not charge the battery in areas in the presence of flammable gases.
Disconnect the FX700 from the electrical outlet after charging and do
not leave unattended while charging.
Avoid prolonged exposure to heat for long periods of time, in case of
malfunction – turn it off immediately.
IMPORTANT INFORMATION Read all the operating instructions, safety tips and warnings in the instruction manual. Identifying
potential hazardous situations and observing the appropriate safety rules will avoid accidents.
Dangerous situations to avoid in order to prevent all risks that are shown above. Never use the FX700 inappropriately, but
only as described in the user manual. The Manufacturer reserves the date the technical information contained in this manual
without notice.
Disposal of waste batteries. If this product contains batteries,do not dispose of them with
otherhousehold waste.
Disposal of Electrical & Electronic Equipment. This symbol indicates that this RAEE
product should not be treated as household waste. Instedhand it over to the appropriate
collection point for recycling of electrical and electronic equipment which will
conservenatural resources. If it is not possible to deliver to a collection point, it can be
disposed of through your local retailer.

The Vector Network Analyzer FX700/FX1300 is a useful instrument for the amateur
radio environment for the development of antennas, filters and measurement of
transmission lines.It is based on the initial EU1KY * project, has been redesigned,
modified the firmware and hardware. It is very advanced and aims to surpass the
best features of a commercial VNA without neglecting the simplicity and flexibility
of use. It works on the high bands using the harmonic frequencies with good
precision. Due to its small size, low weight and use of a rechargeable battery pack, it
is perfectly compatible with all the requirements of a modern Radio Amateur, both
in the workshop, shack and outside. It can be used:
- Fast check of all antenna parameters
- Coaxial cable length measurement
- Export graphics to your computer
- Detailed screenshots of the measures
- Quickly measure resonance of multiband antennas
- Comparison of many types of antennas
- Generate RF signals
- Measurement of the series and parallel parameters of the quartz
- Complete OSL calibration (open,load,short)
- TDR chart (time domain reflectometer)
It can easily and quickly measure all the parameters of an antenna or a transmission
line including:
●SWR /Returnloss
●Automatic / best SWR
●Impedance Z
●Resistance R
●Reactance X (sign)
●Rs/Ls - Rp/Lp
All measurament are displayed simultaneously and can be shown graphically on the
display.
Using convenient menus you can choose measurements of multiband antennas,
crystals, filters or traps - all with extreme simplicity.

Menu for measuring the length of coaxial cables.
It is possible to select the velocity factor for
many types of cable. Selecting SCAN shows the
graph and cable length. Cable failure is also
possible here.
Menu for measuring the basic parameters of
quartz:
Fs/Fp: resonance serial/parallel
Cs/Cp: capacity serial/parallel
Ls: inductance
Rs: resistance
Q: quality factor
Menu Generator: possibility to select the
frequency and set steps. A square wave and all
harmonic frequencies will be generated on the
DUT connector, no filtering expected.

The calibration is necessary to compensate the
cables connected on the DUT, this moves the
reference plane to the end of the cable.
Proceed with calibration by connecting in
sequence SHORT/LOAD(50ohm)/OPEN tool and
then SAVE calibration.

FX700/FX1300 offers two types of calibration:
1) Hardware calibration*
2) OSL user calibration.
The HW calibration is made in the factory. User
can redo it by positioning the rear switch to the
right position and proceeding with the
calibration. This calibration is done only once
and it is not necessary to repeat it. (The switch
could be inside the enclosure, in this case you
need to remove the rear cove).After calibration,
reposition the rear switch to the left position.
OSL kit* not included
*use a better quality calibration kit.
