CHANNELS
 Get the number of analog input channels on a device.
Message
"@AI:CHANNELS"
Response
implementation FIXED%, PROG% (programmable), or not specified if value is
NOT_SUPPORTED
value The number of A/D channels on a device, or returns
NOT_SUPPORTED if the device doesn't support analog input.
Example "AI:CHANNELS=FIXED%8"
Note On some devices, the values returned may be dependent on channel configuration
settings.
CHMODES
 Get the analog input channel modes that are supported by the device.
Message
"@AI:CHMODES"
Response "AI:CHMODES=implementation>value<dependent properties>"
implementation FIXED%, PROG% (programmable), HWSEL% (hardware
selectable), or not specified if value is NOT_SUPPORTED
value SE or DIFF, or returns NOT_SUPPORTED if the device doesn't
support analog input.
dependent
properties
One or more property that is dependent on the value of another
property. For example, the CHANNELS property is dependent on
whether the CHMODES value property is set to SE or DIFF.
Example "AI:CHMODES=PROG%SE,DIFF"
FACCAL
 Get a value indicating if the device supports factory calibration for analog inputs.
Message
"@AI:FACCAL"
Response "AI:FACCAL=implementation>value"
implementation FIXED%, or not specified if value is NOT_SUPPORTED
value SUPPORTED, NOT_SUPPORTED
Example "AI:FACCAL=FIXED%SUPPORTED"
