National Instruments PXIe-5423, Calibration Procedure

•

Timeout

: 10 s

•

Frequency

: Frequency returned by the 

Current Configuration

 output of niFgen

ni5433 Flatness Cal Configure in the previous step

14. Wait 1 second for settling.
15. Measure the power of the signal using the power sensor.
16. Call niFgen ni5433 Flatness Cal Adjust with the following settings:

•

Measured Power (dBm)

: Power of the waveform present on CH 1 of the

PXIe-5423 and measured by the power sensor in the previous step in dBm

17. If the 

Flatness Cal Complete

 output of niFgen ni5433 Timebase Cal Adjust returns

FALSE

, repeat steps 12 through 16 until 

Flatness Cal Complete

 returns 

TRUE

.

Reverification

Repeat the 

Verifying the PXIe-5423

 on page 6 procedures to determine the as-left status of the

PXIe-5423.

Note

If any test fails reverification after performing an adjustment, verify that you

have met the test conditions before returning your PXIe-5423 to NI. Refer to the 

NI

Services

 section for information about support resources or service requests.

Setting the Calibration Date and Due Date

After completing all verifications or reverifications, set the calibration date and a calibration
due date for the PXIe-5423 using either Measurement Automation Explorer (MAX) or the
LabVIEW NI System Configuration API.

NI recommends a calibration due date of the date of external calibration plus the external
calibration interval for the PXIe-5423.
•

MAX—Navigate to the External Calibration section of the Settings tab and update the

Calibration Date

 and 

Calibration Due Date

 entries. Click Save.

•

LabVIEW NI System Configuration API—Use the Update Calibration VI to set the

calibration date

 and 

calibration due date

.

The calibration due date can be either a specific date or an interval in months.
