CAL_DC?
Lists the steps of an interactive calibration procedure or a portion of a procedure
as it would run when requested by a CAL_DC command with the same
parameters.
Parameters
1. INPUT1 or INPUT2 (The input to be used, signifies dc calibration), or
WBND for Option 5790B/3 or Option 5790B/5 Wideband gains calibration.
2. (Optional) A number that defines the range amplitude (same as for the
RANGE command). If this parameter is included, list only the steps for the
specified range; if not included, list steps for all ranges.
Response
(IAD) A list in the following form:
<# of ranges><EOL>
<range 1 max>,<# of steps in range><EOL>
<1st step amplitude in volts>,<1st step frequency in Hz><EOL>
<last step amplitude>,<last step frequency><EOL>
<range 2 max> etc.
CAL_FPT
Corrects the reference given for an ac calibration step after the fact, and as a
result changes the calibration constant or constants determined in that step.
Parameters
1. A number signifying the range amplitude (as in the RANGE command)
2. The number of the step to correct (obtained using the CAL_FPT?
command).
3. The updated reference value divided by what was given as the reference
when the calibration step was run. (1.0 means no change, more than 1.0
means the reference is bigger than you said when you did the
CAL_NEXT.)
Example
CAL_FPT?
(returns) 2.20000,0
CAL_NEXT?
(returns) 2.0E+0,1.00E+6
CAL_NEXT 2.0
CAL_FPT 2.2,0,1.00019
CAL_FPT?
Supplies the first two parameters to be used with a CAL_FPT to correct the next
calibration step to be performed.
Parameter
None
Response
1. (Float) A number signifying the range amplitude (as in the RANGE
command)
2. (Integer) The number of the step to correct (using the CAL_FPT
command).
