NI PXIe-5624R Calibration Procedure
Verification
The performance verification procedures assume that adequate traceable uncertainties are
available for the calibration references.
Verifying Internal Frequency Reference
This procedure verifies the frequency accuracy of the NI 5624R onboard frequency reference
using a signal generator. Use digitizer mode of the NI 5624R. Use
Interactive IF
Acquisition Without DSP (Host).vi
in the Multirecord Acquisition sample project as
a starting point.
1.
Connect the signal generator RF OUT front panel connector to the NI 5624R IF IN front
panel connector using an SMA (m)-to-SMA (m) cable.
The following figure illustrates the hardware setup.
