# Set the frequency to 1 MHz
signal_generator.set_frequency(1e6)

# Set the amplitude to 1 Vpp
signal_generator.set_amplitude(1)

# Enable the output
signal_generator.enable_output()

# Disable the output after 5 seconds
time.sleep(5)

# Disconnect from the signal generator
signal_generator.disconnect()

Make sure to replace "TCPIP0::192.168.1.1::INSTR" with the actual resource name or address of your Keysight 33220A RF Signal Generator.
