150 OUTPUT 723;"CHOP ON;"

The CHOP command turns the input and light for chop mode on or o￿.

Provided the sweep times are long, the CHOP command increases dynamic range. CHOP mode subtracts the ambient light from the signal. With CHOP mode ON, the instrument automatically enables chop mode for sweep times 40s, or longer. CHOP mode is disabled when it is set to OFF.
