class hardware_control.instruments.srs.SRS_DG535.SRS_DG535(instrument_name: str = 'SRS_DG535', connection_addr: str = '')

Bases: Instrument

Stanford Research Systems DG535 instrument class.

The instrument uses GPIB (tested with a NI-GPIB-usb adapter) and is controlled using the pyvisa library. The DelayGenerator control implements most of the device’s features.

PARAMETERS
  • TRIGGER_MODE (INTERNAL, EXTERNAL, SINGLE, BURST)

    • Trigger mode.

  • TRIGGER_EDGE (POS, NEG)

    • Trigger edge – either falling (POS) or rising (NEG).

  • TRIGGER_LEVEL (float)

    • External trigger voltage.

  • TRIGGER_PERIOD (int)

    • Period (in milliseconds) of one trigger in a burst (between 2 and 37266).

  • INTERNAL_TRIGGER_RATE (int)

    • Trigger frequency (in Hz) while in internal trigger mode. Only available in Internal mode.

  • BURST_TRIGGER_RATE (int)

    • Trigger frequency (in Hz) while in burst trigger mode. Only available in Burst mode.

  • PULSES_PER_BURST (int)

    • Number of pulses in a burst (between 2 and 32766).

  • CH<X>_OUTPUT_MODE (TTL, NIM, ECL, VAR)

    • Channel ‘X’ output mode (transistor-transistor logic, nuclear instrument modules, emitter-coupled logic, or variable)

  • CH<X>_OUTPUT_OFFSET (float)

    • Voltage output offset of channel ‘X’. Only available in variable output mode.

  • CH<X>_OUTPUT_AMPLITUDE (float)

    • Voltage output amplitude of channel ‘X’. Only available in variable output mode.

  • CH<X>_DELAY (float)

    • Delay time (in seconds) of channel ‘X’ with respect to another channel (see ‘CH<X>_RELATIVE_TO’).

  • CH<X>_RELATIVE_TO (‘T0’, ‘A’, ‘B’, ‘C’, ‘D’)

    • Channel with respect to which the delay on channel ‘X’ is applied (see ‘CH<X>_DELAY’).

  • CH<X>_TRIGGER_IMPEDANCE (50-OHMS, HI-Z)

    • Trigger input impedance of channel ‘X’.

COMMANDS
  • SINGLE_TRIGGER

    • Set the instrument to trigger once.

numeric_to_alpha(value)
try_connect()

Need to clear the buffer every time we start the instrument.
