Signální FM generátor digitální 0,5 až 470 Mhz. Napájení 8V až 12V max

Na generátoru si můžete nastavit požadovanou frekvenci od 500 Khz až do 470 Mhz. Generátor do této frekvence zamixuje NF frekvenci třeba 1Khz nebo 2Khz max 3Khz. kterou uslyšíte na vašem přijímači. Na přístroji si můžete nastavit hlasitost NF signálu dB. Generátor se používá ke kontrole přijímačů a také se podle něho může přijímač vyladit na požadované počáteční a konečné pásmo třeba FM přijímače. Ovládání je digitální a můžete si nastavit silu jak vysílaného signálu tak signálu NF ukazatel je v dB decibelech. Zde jsou technické parametry generátoru. High frequency signal source, radio frequency signal source (0.5-470MHz)1. specially for FM interphone debugging2. frequency 0.5MHz-470MHz3. the output signal strength is -70 to -132dBm (other values are invalid).4. built in 800Hz audio modulation (FM mode modulation).5. using 8-12V DC power supply6. frequency 7 digit example: 439.0125MHz display 4390125 if 439.125MHz display 43912507. (prohibit the input power, once the input exceeds 0dbm power will burn the signal source).8. random no power supply, no test line, no paper instructions, specific operation methods see webpage introduction.The operation method is as follows:The F1: cycle chooses to set the item "to" the selected item, the frequency, the signal strength, and the frequency of the audio modulation respectively.Backspace key for F2: input errorF3: turn off, open signal outputF4: turn off, open audio signal modulationNumeric key: directly input the number of selected itemsUp and down key: step to modify the value of the selection projectBe careful:It is forbidden to input power. Once input power exceeds 0dbm, the signal source will be burned. The damage caused by input power is not guaranteed.The signal source description of the interphoneSignal source mode:First line left frequency (0.5-470M), right output power (-90 ---131dBm)The second line is on the right subaudible (50.0-280.0Hz analog analog subtone and 105 digit subtone) on the right side of the modulation tone (1-3K).Digital keys: direct input for the cursor to the projectUp and down key: step adjust the cursor to point to the value of the projectF1 key: the cursor points to the movementF2 key: backspace keyF3 key: function keys cursor output power, subsonic and modulation sound cycle switch function, example: cursor power output of the key function for the cycle switch signal output.F4 key: UnusedAnalog sub tone settings: direct input of 4 digit subaudible points, not enough 4 bit front complement "0" example 88.8Hz input 0, 8, 8, 5Now, if you use up and down key adjustment will be 0.1Hz step adjustment, if you need to adjust the standard 50 sets of subtone to input 0, 0, 0, 0 then use the upper and lower key adjustment will start from the first standard subtone 67Hz.Digital subtone settings: input 3 bit digital subtone code and then press F3 case 023 to enter 0, 2, 3 and then press F3 to set up successfully. According to F2 key, you can switch between I and N in the digital subtone, and the adjusted up and down key will be added and reduced in the 105 group of digital subsounds.Modulation and subtone input 0 is equivalent to closing.Step frequency setting: when the cursor is pointing to the frequency, it will be saved as stepping frequency according to the current display frequency of F3.Fast input integer frequency: example input 4, 3, F3 is 430. K napájení generátoru používejte nejlépe síťový transformátor. Spínané zdroje způsobují rušení hlavně vysílaného NF signálu.
