Nearly 1000 KVE-60 antenna analyzer HAM enthusiasm for participation and feedback
After the test of time again upgrade will bring you more strong feelings!
The first KVE-60C diagrams of shortwave antenna vector impedance analyzer, is based on a measurement device of shortwave antenna system 50 ohm. To get an accurate measurement of reactance of X, SWR, R, standing wave resistance and impedance parameters of Z composite. Resonant, used to check and adjust the shortwave antenna bandwidth, matching. The antenna analyzer requires the user to have a certain knowledge of the basic theory of radio, and to understand the performance of the device; in order to better operate correctly and use it.
Secondly, the developer is a radio amateur, design concept and try to commercial works different, is the pursuit of:
1, accuracy! Accuracy! Reliable!
2, fast! Simple! Easy to use!
3, regardless of the cost, born to have a fever!!
It is not so much what the function: can't test frequency, not as LCR said, can't.... Even after a large number of batch experiments, testing, trial, release and improvement. But the device is still possible there may be some does not affect the measurement and test of BUG. The device as a DIY works, compared with the business machine housings appearance might regret. But this should not be a great pity.
But the device has higher resolution and accuracy than the commercial machines, test speed, more friendly operation interface, pay more attention to the user experience, small size and portable power management quality, to get more time etc..
The main specifications:
1 display: sharp transflective TFT
(the sun's performance is superior, is also very expensive, mainland and island no this TFT this technology)
2 standing wave range: 1.00-99.99
(market million below the instrument, no one can reach the index and the accuracy of such)
The 3 frequency range: 0.5-60MHz
4 frequency stability: <5PPM
(stability of bridge signal source is the most basic guarantee, the precision and reliability of measurement by using LC oscillator architecture of the MFJ-269, Comet CAA-500 and other talent, do the Rockets will not catch up, their data can only be setting analysis of rough)
The 5 step: the minimum 100Hz/ step frequency
(the same talent no do, this measurement resolution, which is very meaningful, for narrowband antenna measurements such as small loop antenna)
The 6 output level: 5dBm (based on characteristic parameters of 14MHz test)
(meet the relevant regulations in most regions.)
The 7 sweep width: 250K/500K/1M/2M/5M/10M/20M/50M
8 step: 1KHz/2KHz/4KHz/8KHz/20KHz/40KHz/80KHz/200KHz scanning
The 9 impedance range: 0.1-999.9 ohmic resistance and reactance
(bridge reference resistor 60C is used: the stability of 0.1% precision and 10PPM; reference capacitor is used: a precision of 1%. Million yuan of similar products in the highest), configuration
The 10 power supply: 3.7V 1800mAH lithium polymer (standard built-in)
(power management solutions, 60C extremely efficient. In addition to the battery awesome, users only need to use a few months of intermittent charging often reported.)
11 charging power supply: Micro USB standard connector (must ensure the output voltage is 5.0-5.5V DC, and the output current capability of >=600mA)
(extremely convenient, do not need other charger)
12 charging indicator: hidden (non state of charge can not see),
(there are three: 1, indicating the state of charge (red), 2 the end of charge (green) 3, charging fault (scintillation))
Note: if the charging of long-term idle equipment, must be fully charged, and 2-3 months to check the time. If the lack of electricity, please timely, in order to protect the service life of lithium battery. Domestic users, recommend the use of intelligent mobile phone charger, such as millet, Nokia, Samsung, the original charger.
The reset hole remark: Although the 60C operating system is reliable, the application has been verified in industrial frequency heating machine interference environment. But in order to meet the regional regulations related to national requirements, or at the top left of the machine, set up a hardware reset hole. In case of strong interference cause system crash case: can use the pen, clips, gently pressing operation.
Under normal circumstances, do not operate it!! Remember!!
Should you according to our experience, never need to operations to it.
