Model 2090 Multi-Device Controller
LD
Compatibility:
1050, 1060
Description:
Loads a position/limit value. Used for the setting of the CP, CL, LL, UL, and
WL.
This command is obsolete.
For programs which will not be used with a
model 1050 or 1060, use the 2090 CP, CL, LL, UL, and WL commands.
Devices:
Towers, Turntables
Syntax:
LD [+/-] XXX[.X][CM/DG] <value>
+
Optional for positive values
-
Necessary for negative values
XXX[.X]
Decimal value for the value to be set in centimeters
for towers and degrees for turntables.
In N1 mode .X is ignored
In N2 mode .X is optional.
Leading zeros are optional.
CM

<value>
CP, CL, LL, UL, or WL
Example:
CALL ibwrt (TowerUD%, "LD 100 UL")
' Set tower upper limit
' to 100 cm
CALL ibwrt (TableUD%, "LD 100.7 CP")
' Set turntable current
' position to 100.7 degrees

LH
Compatibility:
1090, 2090
Description:
Changes the lower limit of the device for horizontal polarity. The specified
value must be less than the upper limit for the horizontal polarization and
between -999.9 and 999.9. Note that, unlike editing from the front panel, the
2090 allows setting the limit above the current position from the GPIB.
Devices:
Towers
Syntax:
LH [+/-] XXX[.X]
+
Optional for positive values
-
Necessary for negative values
XXX[.X]
Decimal value for the lower limit to be set in
centimeters.
In N1 mode .X is ignored
In N2 mode .X is optional.
Leading zeros are optional.
Example:
CALL ibwrt (TowerUD%, "LH 235.8")
' Set horizontal polarity lower
' limit to 235.8 cm
