Teledyne T3AFG Arbitrary Waveform Generator¶
- class pymeasure.instruments.teledyne.TeledyneT3AFG(adapter, name='Teledyne T3AFG', **kwargs)¶
Bases:
SCPIMixin
,Instrument
Represents the Teledyne T3AFG series of arbitrary waveform generator interface for interacting with the instrument.
Initially targeting T3AFG80, some features may not be available on lower end models and features from higher end models are not included here yet.
Future improvements (help welcomed):
Add other OUTPut related controls like Load and Polarity
Add other Basic Waveform related controls like Period
Add frequency ranges per model
Add channel coupling control
- ch_1¶

- ch_2¶
- Channel:
- 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 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.
- 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.
- class pymeasure.instruments.teledyne.teledyneT3AFG.SignalChannel(parent, id)¶
Bases:
Channel
- property amplitude¶
Control the amplitude of waveform to be output in volts peak-to-peak. Has no effect when WVTP is NOISE or DC. Max amplitude depends on offset, frequency, and load. Amplitude is also limited by the channel max output amplitude.(dynamic)
- property frequency¶
Control the frequency of waveform to be output in Hertz. Has no effect when WVTP is NOISE or DC.(dynamic)
- property max_output_amplitude¶
Control the maximum output amplitude of the channel in volts peak to peak.(dynamic)
- property offset¶
Control the offset of waveform to be output in volts. Has no effect when WVTP is NOISE. Max offset depends on amplitude, frequency, and load. Offset is also limited by the channel max output amplitude.(dynamic)
- property output_enabled¶
Control whether the channel output is enabled (boolean).
- property wavetype¶
Control the type of waveform to be output. Options are: {‘SINE’, ‘SQUARE’, ‘RAMP’, ‘PULSE’, ‘NOISE’, ‘ARB’, ‘DC’, ‘PRBS’, ‘IQ’}
