How to retrieve the FLF board revision

Agilent ChemStation
The FLF board revision can be retrieved with the following ChemStation command:
PRINT SENDMODULE$(LFLD,"FLFR?")
The reply will be: RA 0000 FLFR "AAAA" for revsion A boards.
Control Module (G1323A/B)
1 Select FLD TESTS
2 Press m.m (m-dot-m)
3 Select Command 4 Type: FLFR?

With all FLF board revisions below, the user interface did not switch
from Ready (green) to Error (red) when the lamp turned off or did
not ignite. So, the user had the impression the lamp is on but it was
not. Now the voltage on the FLF board that is supplied to the FLL
board and trigger pack is monitored. If the lamp is flashing, the
voltage shows regular voltage drops. If these are missing (and the
lamp should be on), then an error (RE 6721 "NO LIGHT DETECTED")
is generated.
Needs minimum firmware A.04.06.
Raman ASTM signal to noise spec is >400
