from qcodes import Station
from qcodes.instrument_drivers.Keysight.Keysight_B2962A import KeysightB2962A

# Create a station to hold the instrument
station = Station()

# Connect to the instrument
instrument = KeysightB2962A('power_supply', 'TCPIP0::192.168.1.1::inst0::INSTR')

# Add the instrument to the station
station.add_component(instrument)

# Print the instrument IDN
print(instrument.get_idn())

# Set the voltage and current for channel 1
instrument.ch1.source_voltage(1.0)

# Enable channel 1
instrument.ch1.enable('on')

# Measure the voltage and current for channel 1
voltage = instrument.ch1.voltage()
current = instrument.ch1.current()

# Print the measured values
print(f"Voltage: {voltage} V")
print(f"Current: {current} A")

# Disconnect from the instrument
instrument.close()
