One powerful signal source with functions such as signal modulation, frequency scan, TTL synchronous output, reference clock output function, Burst & frequency indicator and etc.
Signal modulation function
It means during signals to be modulated, amplitude, phase or frequency variation embedding low-frequency information into high-frequency carrier signals, the resulting signals can transmit any signal from speech, to data, to video. Signal modulation could be divided into analog modulation and digital modulation. Analog modulation such as amplitude modulation (AM) and frequency modulation (FM) are popular during broadcast communication. Digital modulation is based on two conditions and allow signal to represent binary data.
Frequency scan function
Measuring the frequency characteristics of electronic devices requires "scanning" sine waves, which change frequency over time. Generally divided into linear (Lin) sweep frequency and logarithm (Log) sweep frequency; Advanced signal generators support sweep function, and can choose the start frequency, hold frequency, stop frequency and related time, some signal generators also provide synchronization with sweep trigger signal.
TTL synchronous output function
The TTL synchronous signal output by the general signal source is the square wave converted by the triode circuit, and the level is 0 (Low) and 3.6-5v (High). Mainly used to synchronize other signal sources, or other types of instruments, to ensure that the trigger synchronization.
Reference clock output function
TTL synchronous output can only ensure the triggering of synchronization. In order to fully synchronize the signal sources, the clock should be synchronized. The reference clock output is designed to synchronize the clocks of two signal sources.
Similar to the One Shot function, input a TTL signal, the signal source can produce a period of signal output, the design is no signal input, the output can be grounded.
