Pyvisa Dingyang waveform generator simple control [Copy link]

import pyvisa,time
rm = pyvisa.ResourceManager()
# 打印资源名称
print(rm.list_resources())

WaveG=rm.open_resource('资源名称')
#打印资源信息
print(WaveG.query("*IDN?"))
#设置基本波形
WaveG.write("C1:BSWV WVTP,RAMP")
#等待1s
time.sleep(1)
#C1 输出波形
WaveG.write("C1:OUTP ON")

Need to download NI VISA controls in advance

#导入数组的库
import array as arr

import time
#定义测试时间
Times=15
#定义数组
datas=arr.array("i",[])
#使用"a"写入会在 text.txt 后面补上
#使用"w"下次运行会覆盖上次数据
with open("text.txt", "a") as file:
    while Times>0:
        #睡觉1s
        time.sleep(1)
        #将Times 放在数组最后面
        datas.append(Times)
        #将数据转换为 str
        file.write(str(Times))
        #手动回车
        file.write(" Times  \n")
        #时间-1
        Times-=1
#打印数据
print(datas)

With a small piece of code, save the test content to txt

This thing still needs external control. There should be a control software inside so that I can just select it directly.

There is control software, but it is not so easy to use

I remember that Keysight's oscilloscope also comes with a 20M waveform generator, which can be set directly in it

Many have built-in waveform generators, and the significance of pyvisa is to automatically collect data
