Picotech

hardware_control.instruments.picotech.Picoscope module

Control class to handle different picoscopes.

Currently supports 2000, 5000, and 6000 Picoscopes.

class hardware_control.instruments.picotech.Picoscope.Picoscope(instrument_name: str, pico_series: str, channels: List, timeout_ms: int = 20000)

Bases: Instrument

Picotech Picoscpe 2000a and 5000a series instrument class.

Notes

1. The picoscope.ps5000a python library is meant for both 5000a and 5000b series instruments. 2. Picoscope channels are numbered such that the first channel is 0.

PARAMETERS

• TIMEBASE (float)

  • Horizontal resolution in time per division.

• TIME_OFFSET (float)

  • Time offset from trigger.

• TRIGGER_LEVEL (float)

  • Trigger level.

• TRIGGER_EDGE (BOTH, NEG, POS, ALT)

  • Edge of waveform that the picoscope triggers on.

• TRIGGER_CHANNEL (int)

  • The channel (1,2,3, or 4) to trigger on.

• CH<X>_VOLTS_DIV (float)

  • The voltage per division for channel ‘X’.

• CH<X>_OFFSET (float)

  • The voltage offset for channel ‘X’.

• CH<X>_ACTIVE

  • On/off status of channel ‘X’.

• CH<X>_PROBE_ATTEN (float)

  • Probe attenuation for channel ‘X’. For example, providing the value ‘10’ would indicate a 10x or 10:1 probe.

• CH<X>_COUPLING (AC, DC)

  • Coupling mode for channel ‘X’.

• CH<X>_WAVEFORM

  • Most recent waveform measurement from channel ‘X’.

COMMANDS

• SINGLE_TRIGGER

  • Set the instrument to trigger once.
