Command Reference B-7
:SOURCE
(:CALibration:PROTected:SOURce)
Purpose
To calibrate the source function.
Format
:cal:prot:sour <nrf>
Parameter
See Table B-3.
Description
The :CAL:PROT:SOUR command calibrates the Model 2400 source func-
tion. To use this command, you must (1) program the source to the correct
value, (2) select the range being calibrated, and (3) send the
:CAL:PROT:SOUR command for each parameter listed in Table B-3.
Note
When the Model 2400 receives this command, it will attempt to place the
parameter into one of the four parameter ranges summarized in Table B-3,
depending on the active :SOUR:FUNC and range. If the parameter does not
fit into any of the four allowed ranges, an error number -222, “Parameter
data out of range,” will be generated. Once the unit has successfully selected
the appropriate parameter range, it will then check to see if the active source
is programmed to a value within the selected parameter range and that
:OUTP:STAT is ON. If the active source is not programmed to a value
within the parameter range (or if the source is in autorange or in standby),
an error number -221, “Settings conflict,” will be generated. If no error
occurs, the active source function/range point will be calibrated using the
corresponding parameter.
Note that parameters for a given source function and range may be sent in
any order. However, once one :CAL:PROT:SOUR command executes, the
other three must also be executed, or an error number -200, “Execution
error,” will occur when the :CAL:PROT:SAVE command is processed at the
end of the calibration procedure.
Because the source is calibrated for both positive and negative values, two
zero calibration points are required. The Model 2400 automatically uses the
appropriate zero parameter based on whether the source polarity is positive
or negative.
Example
:CAL:PROT:SOUR 2
Calibrate 2V source range.
