Parameter Tables
Changeover tables for grating turrets, filter wheels and detector port need to have their
parameters entered as tables. A table consists of a list of records, each having a wavelength and
the corresponding selected device number. The prompt indicates the record number with
wavelength and device. The cursor is positioned at the start of the parameter to be edited, first
the wavelength is edited and then the selected device number. Each parameter is viewed or
entered in turn with the
ENT
key
.
The
ENT
key moves through the fields. After the position field it
goes to the next record's wavelength field. The first record's wavelength is always zero and
cannot be edited. At the last record the
"ENT"
saves the table. For creation of tables smaller than
an existing table's size, enter
0
wavelength and
0
position in unused records.
All records must
be entered to accept any portion of the table.
Example:
>[Shift] [Grat]
Wav:Gr>O:1 [ENT]
Wav:Gr>200:2 [ENT]
Wav:Gr>200:2 [ENT]
Wav:Gr>300:3 [ENT]
Wav:Gr>300:3 [ENT]
Wav:Gr>500:4 [ENT]
Wav:Gr>500:4 [ENT]
In the above example, the keys Shift and Grat were pressed to display the Grating Table. The
response displayed the parameters for the first record. In this case, the first grating was already in
the active position. W hen ENT was pressed the second record is displayed and the cursor is at
the start of the changeover wavelength. The wavelength was changed to 250. When ENT was
pressed, the wavelength was accepted and the cursor is on the grating position. This process
was repeated until all the records were accepted.
