Products Description
definition
Rf signal generator is a basic test instrument that must be used in the field of RF and microwave testing and development. It is different from other equipment such as spectrum analyzer and oscilloscope, the signal generator does not measure any indicators, but provides correct test conditions for other test instruments in order to measure the output signal of the measured unit.
type
Rf signal generators mainly include two basic types: (1) Free running frequency signal generation (2) synthetic RF signal generators. The following figure shows the main components
Oscillator: The most important component of the RF signal generator, receiving commands from the controller to set the required frequency of the output
Amplifier: Amplifies the oscillator output signal to a specific power level
Attenuator: helps to ensure the impedance match of the output of the RF signal generator, and can ensure the output level stability accuracy of the signal source by automatically adjusting the attenuator, the general incremental step of the attenuator is 0.1dB
Control: The control center of the RF signal generator, which controls the output frequency, output power, modulation mode, and can also receive remote control commands. Feature
Frequency range: the frequency range that the RF signal generator can output, the wider the general frequency range, the better, but the more expensive the price, at present, the general after 1G, 3G, 6G and higher. Output level: The output level includes the range and accuracy of the output, the range of the general signal source is -140~+20dBm, the accuracy is +0.5dB, and the step is 0.1dB. Modulation: As the modulation format of applications such as mobile communication becomes more and more complex, the requirements for signal generators are also getting higher and higher, and the signal source is required to perform analog and digital modulation, such as AM\FM\QPSK QAM
