The signal generator is a device that can provide various frequencies, waveforms, and output levels of electrical signals. When measuring the characteristics of amplitude, frequency, transmission, and other electrical parameters of various telecommunication systems or equipment, as well as measuring the characteristics and parameters of components, it is used as a signal generator or excitation generator for testing and has a wide range of applications in production practice and technology fields.
A variety of signal generators exist with different generating capabilities. Then, take our SU5602 Pulse Function Arbitrary Waveform Generator as an example to briefly introduce its signal generation capabilities.
It can generate some specific function waveforms (sine, square, triangle, ramp, etc.). You can internally modulate sine, square, and ramp using AM, FM, PM, or FSK.
It not only can generate common waveforms but also can simulate arbitrary waveforms needed in actual circuit testing, users can select any of the seven built-in arbitrary waveforms or their own custom waveforms including CARDIAC, EXP_FALL, EXP_RISE, GAUSSIAN, HAVERSINE, NEG_RAMP, sin(x)/x.
SU5602 is equipped with an arbitrary waveform editor to enable users to achieve arbitrary waveform editing, as shown in Figure 1.

Therefore, in practical applications, arbitrary waveform signal generators are more widely used.
Noise signals are generated with the following specified parameters: amplitude/offset or high/low level, PDF, selectable crest factor. It can be used to measure the performance of the system under testing by introducing a random signal to simulate the noise in the actual operating conditions.
It mainly generates pulse signals with adjustable parameters such as repetition frequency, pulse width, and amplitude. In pulse mode, it is possible to adjust the transition times of the pulse. It can be used to test the transient response of linear systems, or the performance of radar, multichannel communication, and other pulse digital systems with analog signals.
It mainly generates square signals with high and low states and digital signals with specific features and symbol sequences, which can be detected and troubleshot during transmission, and help find problems in communication systems. Bit shape editing makes it easier for customers to simulate real signals, including overshoot, ringing, or distorted level transitions, as shown in Figure 2.
