Save Configuration (F1 4 1); Restore Configuration (F1 4 2); Selecting The Filter Position; Selecting The Filter Switching Speed - Sutter Instrument LAMBDA 10-B Operation Manual

4.6.4.1 Save Configuration (F1 4 1)

If saving the configuration, the following menu is displayed providing you with the choice of
three possible configurations into which to store the current configuration.

4.6.4.2 Restore Configuration (F1 4 2)

If restoring one of the saved configurations, the following menu is displayed providing you
with the choice of three possible configurations from which to restore.

4.7 Selecting the Filter Position

Pressing the corresponding numeric key when the controller is in the local mode chooses a
filter position on the wheel. Keys are read while depressed but the appropriate action will
occur only when the key is released. If a key is pressed while a move is in progress but
released after the move is over, the key will read normally. Keys pressed and released while a
move is in progress are ignored. The filter position currently located in the optical port will
be indicated on the display (see example above).

4.8 Selecting the Filter Switching Speed

To enter the speed selection mode, press the speed key on the keypad. Speed 0 is the fastest
speed and speed 7 is the slowest. Entering the selected speed under computer control is
covered in a separate section.
The switching times (in milliseconds) for each of the eight speeds is given in the Table 4-1.
Note that a 5-filter position move is the longest move on the 10-position filter wheel since the
controller will always rotate the correct direction to make the fastest change of position. For
a given speed, the time for a move to a non-adjacent filter will take about 1.8, 2.5, 3.3 or 4
times as long as a move to an adjacent filter, depending on the number of filters to be
skipped. The highest speed that can be used will depend on the weight of the filters mounted
in the wheel. With 2 typical filters and 8 blocking disks, adjacent filters can be changed in
less than 90 milliseconds.
