Keithley 2260B DC Power Supply

class pymeasure.instruments.keithley.Keithley2260B(adapter, name='Keithley 2260B DC Power Supply', read_termination='\n', **kwargs)

Bases: SCPIMixin, Instrument

Represents the Keithley 2260B Power Supply (minimal implementation) and provides a high-level interface for interacting with the instrument.

For a connection through tcpip, the device only accepts connections at port 2268, which cannot be configured otherwise. example connection string: ‘TCPIP::xxx.xxx.xxx.xxx::2268::SOCKET’ the read termination for this interface is

source = Keithley2260B("GPIB::1")
source.voltage = 1
print(source.voltage)
print(source.current)
print(source.power)
print(source.applied)

property applied: Control voltage (volts) and current (amps) simultaneously. Values need to be supplied as tuple of (voltage, current). Depending on whether the instrument is in constant current or constant voltage mode, the values achieved by the instrument will differ from the ones set.

check_errors()

Read all errors from the instrument.

Returns: List of error entries.

check_get_errors()

Check for errors after having gotten a property and log them.

Called if check_get_errors=True is set for that property.

If you override this method, you may choose to raise an Exception for certain errors.

Returns: List of error entries.

check_set_errors()

Check for errors after having set a property and log them.

Called if check_set_errors=True is set for that property.

If you override this method, you may choose to raise an Exception for certain errors.

Returns: List of error entries.

clear(): Clear the instrument status byte.

property complete

Get the synchronization bit.

This property allows synchronization between a controller and a device. The Operation Complete query places an ASCII character 1 into the device’s Output Queue when all pending selected device operations have been finished.

property current: Get the current (in Ampere) the dc power supply is putting out.

property current_limit: Control the source current in amps. This is not checked against the allowed range. Depending on whether the instrument is in constant current or constant voltage mode, this might differ from the actual current achieved. (float)

property enabled: Control whether the output is enabled, see output_enabled.

property error: Get the next error of the instrument (list of code and message).

property id: Get the identification of the instrument.

property next_error: Get the next error in the queue. If you want to read and log all errors, use check_errors() instead.

property options: Get the device options installed.

property output_enabled: Control whether the source is enabled, takes values True or False. (bool)

property power: Get the power (in Watt) the dc power supply is putting out.

read(**kwargs): Read up to (excluding) read_termination or the whole read buffer.

read_binary_values(**kwargs): Read binary values from the device.

read_bytes(count, **kwargs)

Read a certain number of bytes from the instrument.

Parameters

count (int) – Number of bytes to read. A value of -1 indicates to read the whole read buffer.
kwargs – Keyword arguments for the adapter.

Returns bytes

Bytes response of the instrument (including termination).

reset(): Reset the instrument.

shutdown(): Disable output, call parent function

property status: Get the status byte and Master Summary Status bit.

property voltage: Get the voltage (in Volt) the dc power supply is putting out.

property voltage_setpoint: Control the source voltage in volts. This is not checked against the allowed range. Depending on whether the instrument is in constant current or constant voltage mode, this might differ from the actual voltage achieved. (float)

wait_for(query_delay=0)

Wait for some time. Used by ‘ask’ to wait before reading.

Parameters: query_delay – Delay between writing and reading in seconds.

write(command, **kwargs)

Write a string command to the instrument appending write_termination.

Parameters

command – command string to be sent to the instrument
kwargs – Keyword arguments for the adapter.

write_binary_values(command, values, *args, **kwargs)

Write binary values to the device.

Parameters

command – Command to send.
values – The values to transmit.
**kwargs (*args,) – Further arguments to hand to the Adapter.

write_bytes(content, **kwargs): Write the bytes content to the instrument.
