CAL_FREQ
Executes the frequency calibration procedure. An error is generated if the
frequency or amplitude measurement is out of range. If an error occurs, the
frequency calibration procedure is not executed. This step is part of service
calibration. This command requires that you set the CALIBRATION MODE state
to SERVICE and unlock calibration security using the CAL_SECURE command.
Parameters
1. INPUT1 or INPUT2
2. A number signifying the input frequency, including units. If no units are
given, HZ are assumed (value must be between 900 Hz and 1.1 kHz
inclusive).
CAL_I2
Begins the INPUT 2 vs. INPUT 1 calibration procedure. This proceeds with
CAL_NEXT, CAL_NEXT?, and so on like CAL_AC and CAL_DC, except you
must use CAL_INPUT? to determine the correct input to apply the calibration
voltage. This step is part of service calibration. This command requires that you
set the CALIBRATION MODE CAL_SECURE state to SERVICE and unlock
calibration security using the CAL_SECURE command.
Parameter
None
CAL_I2?
Lists the values for the INPUT 2 vs. INPUT 1 calibration procedure. It does not
list the input to which voltages are applied. Use CAL_INPUT? for that purpose.
Parameter
None
Response
(IAD) A list in the same form as CAL_AC? and CAL_DC?.
CAL_INPUT?
Returns the input to which you will apply a reference for the next step.
Parameter
None
Response
(CRD) INPUT1, INPUT2, WBND, or NONE
CAL_INTV
Sets the calibration interval. This is stored in nonvolatile memory and used to
calculate the output uncertainty.
Parameter
The number of days in the calibration interval. Must be 90, 365, or 730.
