Self-Calibrating the PXIe-5423
Self-calibration adjusts the PXIe-5423 for variations in the module environment using an
onboard high-precision calibration ADC. Perform a complete self-calibration after the first
time you install the PXIe-5423.
1.
Install the PXIe-5423 and let it warm up for 15 minutes.
Note
Warm up begins when the PXI Express chassis has been powered on and
the operating system has completely loaded.
2.
Self-calibrate the PXIe-5423 by clicking the
Self-Calibrate
button in MAX or calling
niFgen Self Cal or
niFgen_SelfCal
.
The PXIe-5423 modules are externally calibrated at the factory but you should perform a self-
calibration in all of the following situations:
•
After first installing the PXIe-5423 in a chassis
•
After any module that is in the same chassis as the PXIe-5423 is installed, uninstalled, or
moved
•
When the PXIe-5423 is in an environment where the ambient temperature varies or the
PXIe-5423 temperature has drifted more than ±5 °C from the temperature at the last self-
calibration
•
Periodic adjustment for small performance drifts that occur with product aging

Generating Waveforms with the NI-FGEN Soft
Front Panel
Complete the following steps to generate a standard waveform or an arbitrary waveform using
the NI-FGEN Soft Front Panel (SFP):
1.
Launch the NI-FGEN SFP.
2.
Verify that the PXIe-5423 appears on the NI-FGEN SFP display.
3.
If you are using a two-channel PXIe-5423, choose a channel from the
Channel
list.
To generate waveforms on multiple channels, repeat steps 3 and 4 to load a waveform to
each channel.
