• Scaler: Depending on the resolution, the available beams, SKYMAX
results,shrx,shry and filmtype, SCALER ' chooses another shuffle pattern
SCALER related to other commands:
OPTICS 300 DIAGNOSTICS SUMMARY
(lockrange, skymax, scaler, M & C table, autok ...)
--------------------------------------------------------------
LOCKRANGE_ALL (LTL checks PLL's on DRV4X3 boards.
| to be done once or when swapping boards
| typ.freq. range 2000..4000 *28.8 kHz)
v
SKYMAX (tries to saturate all beams: range < lockrange
| output table on screen: all beams must be 4095
| Always runs before "READY to work")
\_____________
|
expose resol.---> v output table on screen
Shr.& Exp.------> SCALER ==> expose shuffle pattern => C-TABLE
Nr.beams -------> ^ pixel pos.(used beams) (Freq&Del)
______________|
/
M-TABLE (Freq.,Cor.,Del. for theoretical 12 beams interlaced)
^ (Stored for filmtype 0 and 1)
|
AUTOK (When knife OK - after testjobs & CALIK - the target
values of "Diff.pos." between beams are obtained
by measuring (SCANK) + correcting:
- first in C-table with shuffle pattern
- finally via a "Reverse" Scaler calculation
=> Cor.value of M-table)
