CAL_SPEC?
Calculates and returns the absolute uncertainty specification for a specific input,
value (and range), and frequency. This is similar to UNCERT?, except
CAL_SPEC uses the parameters you send rather than the most recent input.
Parameter
1. Input binding post (WBND, INPUT1, INPUT2, or AUX)
2. The value at which to show the specification. This parameter selects the
range the same way as in the RANGE command.
3. Frequency at which to show the specification. Use 0.0 for dc.
Response
(Float) The specification in PPM. If there is no specification for the input, 0 is
returned.
CAL_STLST?
Lists the calibration constant groups that have been updated but not saved.
Parameters
• DC (DC calibration)
• AC (AC calibration)
• ZC (DC zeros calibration)
• WDC (Wideband 1 kHz calibration)
• WAC (Wideband Flatness)
• ALL (All of the above; use this to list CAL_I2 constants)
• A group name from Appendix C, for example, AC_2_2V
Response
(String) The list expressed as a string. The form is:
\<number of groups\>,\<1st group\>, etc.
Example
CAL_STLST? DC
1,DC_DAC
CAL_STORE
Stores all calibration constants in the specified group list into nonvolatile memory.
The CALIBRATION secure state must be set to off or an execution fault results.
See CAL_SECURE. (Overlapped command.)
Parameters
• DC (DC calibration)
• AC (AC calibration)
• ZC (DC zeros calibration)
• WDC (Wideband 1 kHz calibration)
• WAC (Wideband Flatness)
• ALL (All of the above; use this to store CAL_I2 constants)
• A group name from Appendix C, for example, AC_2_2V
