5. FIRMWARE COMMANDS AND RESPONSES
39
alphanumeric character strings rather than numerical values. Items in the command prototype
that are surrounded by square brackets “[...]” are optional items and are not always required.
In this section the term <CR> represents the ASCII carriage return character, decimal value 13,
and the character “_” represents the ASCII underscore character, decimal value 95.
CLEAR
Sets the channels of spectral data to zero. The live time and true time counters are also set to
zero. This command is equivalent to the combination of CLEAR_COUNTER and
CLEAR_DATA commands.
CLEAR_ALL
This command clears all spectrum channels, presets, and ROIs. It is equivalent to the
combination of CLEAR_COUNTERS, CLEAR_DATA, CLEAR_PRESETS, and
CLEAR_ROI commands.
Execution Errors:
%131135083<CR>
The command was attempted while spectrum acquisition was
in progress. No action was taken.
CLEAR_COUNTER
Sets the live time and true time counters to zero.
CLEAR_DATA
Sets the channels of spectral data to zero. The ROI flags and presets are not changed.
CLEAR_PRESETS
The live time and true time presets are all set to zero (disabled).
Execution Errors:
%131135083<CR>
The command was attempted while spectrum acquisition was
in progress. No action was taken.
CLEAR_ROI [start],[length]
If start and length are not specified, the region-of-interest flags for the channels in the
window of interest (see SET_WINDOW) are cleared. If start and length are specified,
region-of-interest flags for the channels specified by start and length are cleared.
DISABLE_GAIN_STAB
Stops stabilization of the gain peak while data is being acquired and sets the center channel
to zero. The gain stabilization adjustment is held at its current value until either gain
stabilization is reenabled with the ENABLE_GAIN_STABILIZATION command or
