控制设备仪器————电源初识

import pyvisa

# Connect to the GPIB instrument
rm = pyvisa.ResourceManager()

class PiDevice:
    def __init__(self, addressId):
        self.addressId = addressId
    def PiPower(self):
        whoPower = rm.open_resource(self.addressId)     #设备地址
        return whoPower

device = PiDevice("ASRL3::INSTR")   #创建实例，并手动写入地址参数ASRL3::INSTR，可以借助NI Max读取
whoisPower = device.PiPower()

# Send a command to the instrument
whoisPower.write('MEASure2:VOLTage:DC?')       #要求仪器测量直流电压

# Read the response from the instrument
response = whoisPower.read()
# Print the response
print(response)
