keithley 2000 slow测试的python命令

以下是使用Python进行Keithley 2000慢速测试的示例代码：

import visa
import time

# Connect to Keithley 2000
rm = visa.ResourceManager()
keithley2000 = rm.open_resource('GPIB0::1::INSTR')

# Set up Keithley 2000 for slow measurement
keithley2000.write('SLOW1')  # Enable slow measurement
keithley2000.write('SLOW2')  # Set measurement rate to slow

# Perform slow measurement
for i in range(10):  # Perform 10 measurements
    keithley2000.write('MEAS?')  # Trigger measurement
    time.sleep(1)  # Wait for measurement to complete
    result = keithley2000.read()  # Read measurement result
    print('Measurement {}: {}'.format(i+1, result))

# Disconnect from Keithley 2000
keithley2000.close()
rm.close()

此示例代码使用PyVISA库连接到Keithley 2000并设置其进行慢速测量。然后，它执行10个测量并打印每个测量的结果。最后，它断开与Keithley 2000的连接。
