Test Conditions
The following setup and environmental conditions are required to ensure the PXIe-5413 meets published specifications:
• The PXIe-5413 is warmed up for 15 minutes at ambient temperature. Warm up begins after the chassis is powered and the PXIe-5413 is recognized by the host and configured using NI-FGEN.
• All test instruments are warmed up for at least the period of time stated in the documentation for each instrument and self-calibration is performed. The warm-up time ensures that the test instruments are at a stable operating temperature.
• Keep cabling as short as possible. Long cables act as antennas, picking up extra noise that can affect measurements.
• Verify that all connections to the PXIe-5413, including front panel connections and screws, are secure.
• Use shielded copper wire for all cable connections to the device. Use twisted-pair wire to eliminate noise and thermal offsets.
• Maintain an ambient temperature of 23 °C ± 3 °C.
• Keep relative humidity between 10% and 90%, noncondensing.
4 | ni.com | PXIe-5413 Calibration Procedure
• Ensure that the PXI chassis fan speed is set to HIGH, that the fan filters (if present) are clean, and that the empty slots contain slot blockers and filler panels. For more information about cooling, refer to the Maintain Forced-Air Cooling Note to Users document available at ni.com/manuals.
• Plug the PXI chassis and any other instrument standards into the same power strip to avoid ground loops.

As-Found and As-Left Limits
The as-found limits are the published specifications for the PXIe-5413. NI uses these limits to determine whether the PXIe-5413 meets the specifications when it is received for calibration. Use the as-found limits during initial verification.
The as-left calibration limits are equal to the published NI specifications for the PXIe-5413, less guard bands for measurement uncertainty, temperature drift, and drift over time. NI uses these limits to reduce the probability that the instrument will be outside the published specification limits at the end of the calibration cycle. Use the as-left limits when performing verification after adjustment.
Calibration Overview
Install the PXIe-5413 and configure it in NI Measurement & Automation Explorer (MAX) before calibrating.
Calibration includes the following steps:
1. Self-calibration—Let the PXIe-5413 warm up for 15 minutes before self-calibrating the PXIe-5413 by clicking the Self-Calibrate button in MAX or calling niFgen Self Cal.
2. Verification—Verify the existing operation of the device. This step confirms whether the device is operating within the published specification prior to adjustment.
3. Adjustment—Perform an external adjustment of the calibration constants of the device. The adjustment procedure automatically stores the calibration date and temperature on the EEPROM to allow traceability.

4. Self-calibration—Let the PXIe-5413 warm up for 15 minutes before self-calibrating the PXIe-5413 by clicking the Self-Calibrate button in MAX or calling niFgen Self Cal.
5. Reverification—Repeat the Verification procedure to ensure that the device is operating within the published specifications after adjustment.
Refer to the following sections to complete each procedure.

Verifying the PXIe-5413
The performance verification procedures assume that adequate traceable uncertainties are available for the calibration references.
Self-calibrate the PXIe-5413 and all test instruments before beginning the verification procedures.
Note Verification of the PXIe-5413 is complete only after you have successfully
completed all verification tests in this section using the as-found limits.

Verifying Timebase Accuracy
Follow this procedure to verify the frequency accuracy of the PXIe-5413 onboard timebase (TCXO) using an oscilloscope.
Refer to the following table as you complete the following steps.
Table 3. Timebase Accuracy Verification
As-Found Limit As-Left Limit
±(1.5 ppm + 1 ppm per year1) ±0.28 ppm
1. Connect one end of the SMA (m)-to-SMA (m) cable to a channel of the PXIe-5413 and the other end to a channel of the oscilloscope.
Note Timebase accuracy verification can be performed on either channel of
the two-channel PXIe-5413.
2. Lock the oscilloscope to the precision frequency reference using the PXI Clock.
