3.6 Analog Output
The LT360 generates a DC voltage at the Analog Output BNC connector.
This output is always active. It can be useful for driving plotting devices,
chart recorders, or other displays.
There are two polarity modes for this output: Unipolar and Bipolar. When
set to UNIPOLAR, the LT360 will produce voltages in the range of 0.000 to
+3.600 volts. All position values are positive. When set to BIPOLAR, the
range will be 0.000 to ±1.800 volts. Both positive and negative values are
produced.
The LT360 has a scale factor of 10mV/deg for the analog output. The range
can be either unipolar (0 ... +3.600V) or bipolar (0 ... ±1.800V). The output
impedance of the analog output is <200 Ohms.
Although the output is an unbalanced BNC connector, it is highly recom-
mended that the input on the other device be differential to reject ground
noise. Since the smallest resolution of the LT360 is 0.1 degree, the equiva-
lent resolution in the output is 1mV. The input impedance of the other
device should be at least 100K Ohm to prevent loading errors.

Error - 11: Display Controller Address Failure
This error indicates that the CPU in the LT360 cannot communicate with the
display controller. This error should never occur. If it does, a failure of a
component in the LT360 is indicated.
Error - 12: Switch Controller Address Failure
This error indicates that the CPU in the LT360 cannot communicate with the
switch controller. This error should never occur. If it does, a failure of a
component in the LT360 is indicated.
Error - 13: Torque Controller Address Failure
This error indicates that the CPU in the LT360 cannot communicate with the
stepper motor torque DAC controller. This error should never occur. If it
does, a failure of a component in the LT360 is indicated.
Error - 14: Output Controller Address Failure
This error indicates that the CPU in the LT360 cannot communicate with the
analog output DAC controller. This error should never occur. If it does, a
failure of a component in the LT360 is indicated.
