The device has been used for about 2 years.
It was purchased purposefully for service of the analogue network of radio communication. There were devices to compare with: an analyser is in operation (...... ).
I liked at once: the light weight, the Russian-language menu, nothing in excess in the menu of measurements for production purposes.
Specificity of the device is various:
- stationary use in conditions of a metering station,
- visit of a site of remote installation of the radio electronic means,
- control of the output power of the radio electronic means at a point of connection to an antenna on a mast.
For this use the specified weight of 8 kg + accumulator of 2 kg are optimal.
Mechanically reliable: it fell from the height of 3 metres into a "hard" snow bank and did not get scrapes.
Electrically reliable: in the mode of HF generator a transmitter of 25 W was connected to it, the attenuator was not damaged.Reliability
: very high.
The only repair was performed when a signal of the HF generator had been lost. The repair was performed during a week, I do not regret a waste of time: in exchange for it the only defect was eliminated: measurement of deviation when sending a call lasting 2-4 sec.Advantages
: the light weight, the menu for a basic user, all the parameters of analogue radio communication in "one case". The possibility of documentation of parameters in the Excel file.Disadvantages
: not a single after repair.
