Self-Calibration Procedures
The NI 5421/5441 is capable of performing self-calibration, which adjusts
the gain and offset of the main and direct analog paths. Self-calibration uses
only an onboard ADC to measure the output voltage. You can implement
self-calibration on the NI 5421/5441 by following procedures similar to the
Verifying the DC Gain and Offset Accuracy
and the
procedures. However, output impedance, oscillator frequency, and
the calibration ADC cannot be adjusted during self-calibration.
You can initiate self-calibration interactively from Measurement &
Automation Explorer (MAX) or from the FGEN Soft Front Panel (SFP).
Alternatively, you can initiate self-calibration programmatically using
NI-FGEN.
MAX
To initiate self-calibration from MAX, complete the following steps:
1.
Launch MAX.
2.
