 Set the slope in hexadecimal bytes for the current AICAL:RANGE setting.
Message
"AICAL{ch}:SLOPE/HEX=hex value"
Response "AICAL{ch}:SLOPE"
ch The channel number.
hex value The calibration slope in hexadecimal bytes.
Example "AICAL{0}:SLOPE/HEX=0x14B525A3"
Note The hex value is used to preserve the precision of the double precision floating point
value.
 Get the slope in hexadecimal bytes for the current AICAL:RANGE setting.
Message
"?AICAL{ch}:SLOPE/HEX"
or
"?AICAL{ch}:SLOPE"
Refer to the device-specific topics to see whether "/HEX" is supported.
Response "AICAL{ch}:SLOPE=0xhex value"
ch The channel number.
hex value The calibration slope in hexadecimal bytes.

Message
"AICAL:TCCAL=value"
Response "AICAL:TCCAL"
value ENABLE, DISABLE
Example "AICAL:TCCAL=ENABLE"
 Get the value for the TC Cal Measurement option.
Message
