4. FIRMWARE COMMANDS AND RESPONSES
27
LIST_DISPLAY
Not used by the EASY-MCA; included for backward compatibility.
LIST_GAIN_CONV
Lists legal conversion gain settings.
Response:
GAIN_CONV 256 512 1024 2048 4096 8192
8K model.
GAIN_CONV 256 512 1024 2048
2K model.
RESET
No function in the EASY-MCA; included for backward compatibility.
SET_DATA [start, chans],value
If the optional start and chans parameters are included in this command, the range of chan-
nels specified by start and chans is loaded with value. If start and chans are not specified,
sets all channels of spectral data in the window of interest (see SET_WINDOW command)
to the specified value. ROI flags are not affected.
SET_DATA_APPLICATION “string1",”string2"
This is used to store information in the EASY-MCA internal memory that can be used by
other programs, such as sample descriptions and energy calibrations. C
ONNECTIONS
uses
this feature. String1 = the data identifier, 32 bytes maximum; string2 = the data, 128 bytes
maximum.
SET_DEVICE
No function in the EASY-MCA; included for backward compatibility.
SET_GAIN_CONVERSION chans
Sets the conversion gain. The conversion gain defines the number of channels within the
device that will used for spectral data. This has the effect of altering the resolution of the
ADC from 13 bits (conversion gain = 8192) to 9 bits (conversion gain = 512) for the device.
See also SHOW_GAIN_CONVERSION.
Legal Commands:
SET_GAIN_CONVERSION 0<CR>
Conversion gain set to default (8192).
SET_GAIN_CONVERSION 512<CR>
Conversion gain set to 512 channels.
SET_GAIN_CONVERSION 1024<CR>
Conversion gain set to 1024 channels.
SET_GAIN_CONVERSION 2048<CR>
Conversion gain set to 2048 channels.
SET_GAIN_CONVERSION 4096<CR>
Conversion gain set to 4096 channels.
SET_GAIN_CONVERSION 8192<CR>
Conversion gain set to 8192 channels.
