mahos.inst.piezo.E727_3_USB_AO#

class mahos.inst.piezo.E727_3_USB_AO(name, conf, prefix=None)#

E727.3 driver using USB connection of PIPython and DAQ AnalogOut.

Parameters:

  • start_servo (bool) – (default: True) if True, start servo on init.

  • axes_order (tuple[int, int, int]) – (default: [0, 1, 2]) permutation for piezo axes IDs and (x, y, z). When axes_order is [1, 2, 0], the x axis is piezo axis of index 1, and the y (z) axis is index 2 (0).

  • lines (list[str]) – list of strings to designate DAQ AnalogOut physical channels. Order them as [x, y, z].

  • scale_volt_per_um (float) – the AnalogOut voltage scale in V / um. the output voltage is determined by: (pos_um - offset_um) * scale_volt_per_um.

  • offset_um (float) – the AnalogOut voltage offset in um. see scale_volt_per_um too.

  • samples_margin (int) – (has preset, default: 0) margin of samples for AnalogOut.

  • write_and_start (bool) – (has preset, default: True) if False, DAQ Task is started and then scan data is written in start_scan(). True reverses this order.
