QCodes

from qcodes.instrument_drivers.stanford_research.SR86x import SR860

# Create an instance of the SR860 lock-in amplifier
lockin = SR860('lockin', 'TCPIP::192.168.1.1::INSTR')

# Connect to the lock-in amplifier
lockin.connect()

# Perform operations with the lock-in amplifier
# ...

# Disconnect from the lock-in amplifier
lockin.disconnect()

Explanation:

1. Import the SR860 class from the qcodes.instrument_drivers.stanford_research.SR86x module.
2. Create an instance of the SR860 lock-in amplifier with the name 'lockin' and the specified IP address 'TCPIP::192.168.1.1::INSTR'.
3. Connect to the lock-in amplifier using the connect() method.
4. Perform any desired operations with the lock-in amplifier.
5. Disconnect from the lock-in amplifier using the disconnect() method.
