installing your module and letting it warm up for 30 minutes.
Note Warm up begins when the PXI Express chassis has been powered on and the
operating system has completely loaded.
The NI 5646R modules are externally calibrated at the factory; however, you should perform a
self-calibration in any of the following situations:
• After first installing the NI 5646R into your chassis
• After any module in the chassis is installed, uninstalled, or moved
• When the system is in an environment where the ambient temperature varies or the
module temperature has drifted more than ±5 °C from the temperature at the last self-
calibration
• To periodically adjust for small performance drifts that occur with product aging
NI recommends you perform the self-calibration from the installed self-calibration executable
located at Start»All Programs»National Instruments»Vector Signal Transceivers»VST
Self Calibrate. When using LabVIEW, you can also use the niVST Self-Calibrate VI, located
on the Functions»Instrument I/O»Instrument Drivers»NI VST Calibration palette.
