Keithley 2750 Multimeter/Switch System

class pymeasure.instruments.keithley.Keithley2750(adapter, name='Keithley 2750 Multimeter/Switch System', **kwargs)

Bases: SCPIMixin, Instrument

Represents the Keithley2750 multimeter/switch system and provides a high-level interface for interacting with the instrument.

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.

close(channel)

Closes (connects) the specified channel.

Parameters

channel (int) – 3-digit number for the channel

Returns

None

property closed_channels

Reads the list of closed channels

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 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.

open(channel)

Opens (disconnects) the specified channel.

Parameters

channel (int) – 3-digit number for the channel

Returns

None

open_all()

Opens (disconnects) all the channels on the switch matrix.

Returns

None

property options

Get the device options installed.

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()

Brings the instrument to a safe and stable state

property status

Get the status byte and Master Summary Status bit.

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.
