无损检测系统需要激励信号源生成频率、占空比、幅值调节范围大的波形，根据

The non-destructive testing system requires an excitation signal source to generate waveforms with a wide range of frequency, duty cycle, and amplitude adjustment. Depending on the different excitation signals used in non-destructive testing methods, the multi-frequency eddy current testing technology requires a single sine signal, and the radiation electromagnetic non-destructive requires an excitation of more than 300K. Pulse eddy current testing requires a low-frequency square wave. Guan Jia [1] used four schemes to generate pulse signals, comparing their advantages and disadvantages, using SPF40 function signal generator. Due to the skin effect of ferromagnetic materials, the detection of surface layer defects becomes a difficult problem. Xie Lian [2] used low-frequency signal excitation to produce weak coupling effect in order to detect deeper defects. However, as non-destructive testing is developing towards integration and intelligence, it is necessary to design instruments that can be directly integrated and easily carried. MAX038 was born as an excitation source signal. Because of its wide operating frequency range (0.1Hz~40MHz), high stability and high amplitude and duty cycle adjustment accuracy, it is often used in the field of pulsed eddy current nondestructive testing.

Non-destructive detection system needs to generate frequency, duty-blank ratio, amplitude adjustment range of waveforms, according to the use of non-destructive detection different excitation signals, multi-frequency eddy current detection technology needs a single sine signal, ray electromagnetic non-destructive need more than 300K excitation, pulse vortex detection needs low-frequency square wave. Guan Jia used four schemes to generate pulse signals, comparing their strengths and weaknesses, and using the SPF40 function signal generator. The detection of surface defects is a difficult problem due to the skin-warming effect of ferromagnetic materials. In order to detect deeper defects, Xie Lian uses low-frequency signal excitation to produce a weak coupling effect. However, as non-destructive detection is booming towards integration and intelligence, it is necessary to design instruments that can be integrated and portable directly. The MAX038 is caused by the operation of the excitation source signal and is often used in the field of pulse vortex non-destructive detection due to its high operating frequency range (0.1Hz to 40MHz) stability and high amplitude and aspect ratio adjustment accuracy.

Nondestructive testing system needs excitation signal source to generate waveform with large frequency, duty cycle and amplitude adjustment range. According to different nondestructive testing methods, excitation signals are different. Multi frequency eddy current testing technology needs a single sinusoidal signal, X-ray electromagnetic nondestructive testing needs excitation above 300K, and pulsed eddy current testing needs low frequency square wave. Guan Jia [1] uses four schemes to generate pulse signal, compares their advantages and disadvantages, and uses SPF40 function signal generator. Due to the skin effect of ferromagnetic materials, it is a difficult problem to detect the defects on the surface layer. In order to detect deeper defects, Xie Lian [2] used low frequency signal excitation to produce weak coupling effect. However, with the rapid development of nondestructive testing towards integration and intelligence, it is necessary to design a portable instrument which can be directly integrated. MAX038, as an excitation source, is often used in the field of pulsed eddy current nondestructive testing because of its wide frequency range (0.1Hz ~ 40MHz), high stability and high accuracy of amplitude and duty cycle adjustment.<br>
