Self-Calibration Procedures
The NI 5922 includes precise internal circuits and references used during
self-calibration to adjust for time and temperature drift. The digitizer gain,
offset, and flatness are all corrected in self-calibration. Measuring the
accuracy of these internal calibration circuits with another instrument
during external calibration provides traceability for the verification
procedure. Absolute accuracy is ensured by compensating for any error
measured in the internal references.
Note
Self-calibrate the digitizer before you perform verification. NI-SCOPE includes
self-calibration example programs for LabVIEW, CVI, and Microsoft Visual C.
LabVIEW
(
version)\instr.lib\niScope
Calibrate\niScopeCal.llb
LabVIEW VI library containing VIs for calling
the NI-SCOPE calibration API; access
calibration functions from the NI-SCOPE
calibration section of the LabVIEW function
palette
IVI\Drivers\niScope\niScopeCal.fp
CVI function panel file that includes external
calibration function prototypes and help on
using NI-SCOPE in the CVI environment
IVI\Include\niScopeCal.h
Calibration header file, which you must include
in any C program accessing calibration
functions. This file automatically includes
niScope.h
, which defines the rest of the
NI-SCOPE interface
