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=None)
Wait for some time. Used by ‘ask’ to wait before reading.
- Parameters
query_delay – Delay between writing and reading in seconds. None is default delay.
- 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.
