This paragraph AW07A antenna analyzer in addition to having an antenna analyzer and radio frequency meter main function , but also has capacitance , inductance measurement estimation function , attach themselves to very simple detection coil circuit also includes a notch table function immediately . For VHF amateur radio 160 until 70 cm waves within the amateur band antenna feed 50 ohm system testing , adjusting and related experiments .

First, the basic specifications

1 Frequency Range : 160M HF VHF UHF (1.5-490MHz middle of a small amount of merchandise )
(2) Output amplitude : OPEN peak of about 2V.
3 VSWR value (SWR): Test range 1 to 10.
4 complex impedance (Z): Test range 10 to 500 ohms.
5 Power Description : external voltage 10.8 ~ 12.5V 500mA load current over DC power supply , DC Block, positive inside , built- 8 on the 5th battery holder. Recommended to use three groups consisting of 10.8V lithium built power supply, reduce weight ; When using the battery clip to use a good seal on the 5th alkaline batteries . Usually a minimum of eight rechargeable battery 9.6V, the best first comparative test results confirmed that no problem can also be used . Try to avoid higher than 13V power supply for UV segment circuit may be damaged due to excessive power dissipation .
Current consumption : 10V experimental power supply, switch is in the HF band position , LCD backlight off , maximum 150mA; backlight on maximum current of 200mA. UV bands , respectively 165 mA and 240 mA or so.
9.9,Z>1KΩ。”>6 Display: antenna interface open display SWR> 9.9, Z> 1KΩ. The analyzer function, respectively, the first row of the screen shows the frequency values ​​, segmented band switch letters, and the standing wave ratio SWR words , the second row displays – resistance R j reactance : complex impedance Z and SWR values. Display specific instructions refer to the back rest .

Second, the buttons and menus for use

From the power switch PWR, uplink key Up, down key Down, UV band and HF bands switch UV / HF, U -band and V -band switch U / V ( This switch is only in the UV / HF pressed effectively ) a total of five switching frequency selection buttons and a button TUNE and combinations thereof completion of the test function. The following menu is displayed with further instructions :

Boot menu select Help

PWR: Press this button to open a separate power analyzer , designers call sign and menu display backlight on key prompt , immediately press U to turn on the backlight that is about half a second , if you do not press any key , the delay automatically after one second frequency meter and antenna analyzer function selection menu.
In addition, if first press U or D key to turn the power on then enter the inductive or capacitive test status , this function because the instrumentation and test components and test their own distribution parameters influence only way to provide a reference value , not as a standard value basis, but can be a good antenna configuration required for the capacitor and inductor values ​​provide a reference convenience .
Up, Down: prompt on the screen corresponding abbreviations are D and U. Boot automatically stays Show D-FC, U-ANT Analyzer, DC: XX.XXV denote Press D to select the frequency meter function , press U to select an antenna analyzer function , followed by the supply voltage estimates.

Frequency meter for use

Frequency meter in MHz , Fg display the decimal point represent fast gate 3 rms , Sg represents a slow shutter can be displayed after the decimal point 4 rms . Press the U and D keys to switch moment . This analyzer frequency meter even after correction, but because of the signal under test different waveforms and instrument itself its own source of instability in the reference could be errors and other reasons , do not as a frequency standard basis, but the machine can detect unknown provide effective emission frequency reference . Frequency meter antenna terminal to reach the test circuit is given the actual reference field strength REF FS corresponding high frequency voltage values ​​that can predict the antenna sensitive to the electromagnetic environment whether analyzer irresistible influence the test results , if the voltage is too high you can not provide accurate test results , similar products analyzers same problem . This analyzer also has an antenna sensor signal over-voltage alarm function to prevent damage to the machine .
Note: Use the frequency counter function , UV / HF HF switch must be in position , otherwise the screen display FREQ.C SW Error PSE VU / HF SW UP words , suggesting that UV / HF switch please return to the HF position .

Antenna analyzer for use

The analyzer function, respectively, the first row of the screen shows the frequency values ​​, segmented band switch letters, and the standing wave ratio SWR words, the second row of open display Z> 1KΩ and SWR values ​​> 9.9 , the antenna connected to the load or working at high-end frequency when were displayed – resistance j reactance : complex impedance and SWR specific values ​​. In the HF band press U or D key to toggle the corresponding upper and lower wavelength band ; press the UV / HF switch to the VU segment , depending on the U / V key position working on UHF or VHF bands .
UHF band can not provide effective impedance values ​​similar goods analyzer also does not provide effective impedance value , AW07A segment in addition to providing the UHF SWR value , but also provides the corresponding SWR less than two auxiliary signal bars .
TUNE: the frequency control knob , under normal circumstances can change a wide range of continuous test signal frequency value , highly recommended to provide test signals corresponding bands . Frequency of the low-end segment of the U may be prompted Output Error words, the signal range error, please roundabout TUNE, back to the appropriate frequency range. In the U section of the analyzer to provide at least 300MHz to 490MHz range , the test values ​​, far more expensive than similar products in the U section of the analyzer ‘s performance . If the same word appears in other bands there may be mechanical failure or power supply voltage is too low , etc. please do not hesitate to identify the reasons .
