4.12 Maintaining Measurement Precision (Self-Calibration)
92
The instrument corrects the circuitry’s internal offset voltage and gain drift as a form of self-
calibration in order to maintain its measurement precision.
You can select between two self-calibration function execution methods.
Self-calibration timing and intervals
* When using the auto setting
When using the auto setting, self-calibration is performed for 5 ms once every second dur-
ing TRIG standby operation. In the event the TRIG signal is received during a 5 ms self-cal-
ibration, the self-calibration is canceled, and measurement will start after 0.5 ms. If you are
concerned about variation in measurement times, please use the manual setting.

(default)
Configure manually.
Execute at user-selected
timing.
A self-calibration that lasts about 5 ms is performed
between measurements.
Self-calibration is performed at the user's desired tim-
ing using the EXT I/O CAL signal input or a communi-
cations command (:SYSTem:CALibration). Using
this setting prevents self-calibration from being per-
formed automatically at unexpected times.
