Command: EMISSION POLARIZER
Syntax: $PM position
Description: Sets the position of the emission polarizer wheel if fitted. Position
is an integer and may have the following values:
0 clear, 1 vertical polarization filter, 2 horizontal polarization filter.
Power-on default is 0.
Command: EXCITATION POLARIZER
Syntax: $PX position
Description: Sets the position of the excitation polarizer wheel if fitted.
Position is an integer and may have the following values:
0 clear (automatic cutoff filter select), 1 vertical polarizer,
2 horizontal polarizer, 3 blank, 9 clear (fixed, no automatic cutoff
filter). Power-on default is 0. Returns current position if no
parameter specified.
NOTE: Cutoff filter position 5 returned if selected.
Command: EMISSION SLIT
Syntax: $SM position
Description: Sets the position of the emission slit. Position is in range 0 to
20 nm and is rounded to the nearest multiple of 0.1 nm.
Power-on default is l nm.
NOTE: Slit positions below 2.5 nm are uncalibrated.
Command: EXCITATION SLIT
Syntax: $SX position
Description: Sets the position of the excitation slit. Position must be in the
range 2.5 to 15 nm and is rounded to the nearest multiple of
0.1 nm. Power-on default is 10 nm.
NOTE: Slit positions below 2.5 nm are uncalibrated.
