awgs package

awgs.RigolDG800Server module

Provides access to Rigol DG800 series AWGs.

class awgs.RigolDG800Server.DG800Server

Bases: LabradServer

Provides access to Rigol DG800 series AWGs.

__init__()
get_devices(self, c)

Lists connected DG800 AWGs. Note that the function connects to each device to check its ID.

Parameters:

c – A LabRAD context (which is passed on to passed to select_device())

Yields:

A list of strings corresponding to the IDs of connected DG800 AWGs

get_output(self, c, channel)

Check whether an output is enabled

Parameters:

  • c – A LabRAD context (not used)

  • channel (int) – Which channel to get output status. Must be 1 or 2

Returns:

whether the channel’s output is enabled

Return type:

boolean

get_sin(self, c, channel)

Get the settings for a channel with sine output

Parameters:

  • c – A LabRAD context (not used)

  • channel (int) – Which channel to get settings for. Must be 1 or 2

Returns:

The frequency (Hz), amplitude (V), offset (V) and phase (deg) of the channel’s sine wave. If the channel is not in sine mode, returns [0].

Return type:

A list of floats

initServer(self)

Called by LabRAD when server is started. Connects to usb.USB_server.

name = '%LABRADNODE%_dg800'
select_device(self, c, device)

Select a connected DG800 AWG

Parameters:

  • c – A LabRAD context (not used)

  • device (string) – The ID of the DG800 AWG to connect to, as returned by get_devices()

set_gated(self, c, channel, gated)

Sets a channel to either be gated or triggered by the external output

Parameters:

  • c – A LabRAD context (not used)

  • channel (int) – Which channel to set the gating mode for. Must be 1 or 2

  • gated (bool) – Whether the channel is gated (True) or triggered (False)

set_impedance(self, c, channel, impedance=50, inf=False, low=False)

Set the output impedance of a channel either to

Parameters:

  • c – A LabRAD context (not used)

  • channel (int) – Which channel to set the output impedance for. Must be 1 or 2

  • impedance (numeric, optional) – Output impedance in Ohms. Defaults to 50, is coerced to be between 1 and 10000.

  • inf (bool, optional) – Sets the output to high imedance. Takes precedence over the impedance option and low impedance mode. Defaults to False.

  • low (bool, optional) – Sets the output to minimum impedance. Takes precedence over the impedance option. Defaults to False.

set_ncycles(self, c, channel, ncycles)

Sets the number of cycles to run per trigger, if the mode is set to triggered by set_gated().

Parameters:

  • c – A LabRAD context (not used)

  • channel (int) – Which channel to set the number of cycles for. Must be 1 or 2

  • ncycles (int) – The number of cycles to run per trigger. Coerced to between 1 and 500000

set_output(self, c, channel, enable)

Enables or disables one of the AWG’s outputs

Parameters:

  • c – A LabRAD context (not used)

  • channel (int) – Which channel to set the output enable status. Must be 1 or 2

  • enable (bool) – True if the channel is enabled, False otherwise

set_sin(self, c, channel, freq, amplitude, offset, phase)

Get the settings for a channel with sine output

Parameters:

  • c – A LabRAD context (not used)

  • channel (int) – Which channel to get settings for. Must be 1 or 2

  • freq (float) – The frequency in Hertz (1E-6 to 35E6)

  • amplitude (float) – The amplitude in Volts (limited by impedance and amplitude high level settings)

  • offset (float) – The offset in Volts (limited by impedance and amplitude high level settings)

  • phase (float) – The phase in degrees (0 to 360)
