NanoTrak Settings Window

When  the  'Settings'  button  on th e  GUI pan el  is  clicked,  the  'Settings'  window  is

displayed. This panel allows data such scan circle frequency and diameter, and loop

gain to be entered. The various parameters are described below.

6.2.1

Tracking tab

Fig. 6.2 NanoTrak Settings panel - Tracking Tab

Circle

Frequency

 - the frequency of the scanning circle. The circle scanning frequency

lies  in  the  range  17.5  to  87.5Hz.  The  factory  default  setting  for  the  scanning

frequency is 43.75Hz. This means that a stage driven by the NanoTrak makes

43.75 circular movements per second.  Different frequency settings allow more

than one NanoTrak to be used in the same alignment scenario. Refer to Section

5.3.6. for more information.

Diameter Mode

  -  this  setting  allows  the  different  modes  of circle   diameter

adjustment to be enabled and disabled.
If the Diameter Mode is set to '

User

', the circle diameter remains at the value set

by the user in the

parameter. The diameter of the scanning circle

is set in NanoTrak units. The circle diameter is measured on a scale such that 10

units is the width and height of the screen. If, for example, the NanoTrak is driving

a 20 micron actuator, a circle diameter of 1 unit will result in a real diameter of 2

microns. The scanning circle diameter can have values in the range 0 to 5.0 with
