Function Generators Comparison

The capabilities of a function generator vary greatly with its price.  In this blog post, we will provide a function generators comparison of Hantek and Siglent function generators at four different price points ranging from $149.00 to $5,299.00. Additionally, we will discuss EasyPulse technology, propriety software from Siglent useful for waveform generation, which many of the function generators in this list come equipped.

What is a function generator?

A function generator (also referred to as an arbitrary waveform generator) is a tool used to generate electrical waveforms over a range of frequencies, and are typically used to prototype, test, and repair electrical equipment with analog circuits. Standard function generators can produce waveforms of the sine, square, triangular, and saw-tooth shape.

Many Siglent function generators (a popular function generator brand) come equipped with EasyPulse technology.  EasyPulse produces quick rising/falling edge, low jitter, tiny duty cycle waveforms and is not affecting by frequency variation.  Additionally, the pulse edge and width can be fine adjusted in a large range.  Even though a function generator that comes equipped with EasyPulse technology may be more expensive, it extends the wave producing capabilities of the generator several times over, and is worth the added expense.

Advantages of EasyPulse Technology:

  • Outputs pulses with quick rising and falling edge (6 ns) under low frequencies (under 1 Hz)
  • Can output pulses with quick rising/falling edge (6ns) under very low frequency (less than 1Hz)
  • Pulse width can be minimized to 12ns under low frequency, with extremely low duty cycle
  • Parameters of pulse can be easily and immediately changed without updating any waveform data
  • Pulse Edge or width can be widely adjusted

The four function generators we will compare in this blog consist of the Hantek 1025G, the Siglent SDG1050, SDG5162, and the SDG6052X.  We will provide a description of each of the four generators progressing by their price.  At the end of the blog is a Function Generator Specification Comparison Table which lists the key specifications and features of the four function generators mentioned in this list.
