Test Conditions
The following setup and environmental conditions are required to ensure the PXIe-5164 meets
published specifications:
• Allow a warm-up time of at least 15 minutes after the chassis is powered on. The warm-
up time ensures that the PXIe-5164 is at a stable operating temperature.
• Allow all test instruments a warm-up time of at least the stated amount of time in their
specification document. The warm-up time ensures that the test instruments are at a stable
operating temperature.
PXIe-5164 Calibration Procedure | © National Instruments | 7

• 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-5164, 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.
• 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 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 chassis and the instrument standard into the same power strip to avoid ground
loops.

Calibration Interval
Recommended calibration interval 2 years
As-Found and As-Left Limits
The as-found limits are the published specifications for the PXIe-5164. NI uses these limits to
determine whether the PXIe-5164 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-5164,
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.
Measurement Uncertainty
Measurement uncertainty was calculated in accordance with the method described in ISO
GUM (Guide to the Expression of Uncertainty in Measurement), for a confidence level of
95%. The expressed uncertainty is based on the recommended measurement methodology,
standards, metrology best practices and environmental conditions of the National Instruments
laboratory. It should be considered as a guideline for the level of measurement uncertainty that
8| ni.com | PXIe-5164 Calibration Procedure

can be achieved using the recommended method. It is not a replacement for the user
uncertainty analysis that takes into consideration the conditions and practices of the individual
user.
Calibration Overview
Install the device and configure it in NI Measurement & Automation Explorer (MAX) before
calibrating.
Calibration includes the following steps:
1. Self-calibration—Adjust the self-calibration constants of the device.
2. Test system characterization—Characterize the amplitude balance of the output ports on
your power splitter and amplitude loss through your power splitter.
The results of this step are used as a correction in the following procedures:
•Verifying 50 Ω Passband Amplitude Flatness and Bandwidth
•Verifying 1 MΩ Passband Amplitude Flatness and Bandwidth
•Adjusting 50 Ω Passband Amplitude Flatness and Bandwidth
•Adjusting 1 MΩ Passband Amplitude Flatness and Bandwidth
3. Verification—Verify the existing operation of the device. This step confirms whether the
device is operating within the published specification prior to adjustment.
4. Adjustment—Perform an external adjustment of the calibration constants of the device.
The adjustment procedure automatically stores the calibration date and temperature in the
nonvolatile memory to allow traceability.
5. Re-verification—Repeat the Verification procedure to ensure that the device is operating
within the published specifications after adjustment.
Test System Characterization
The following procedures characterize the test equipment used during verification.
Caution The connectors on the device under test (DUT) and test equipment are
fragile. Perform the steps in these procedures with great care to prevent damaging
any DUTs or test equipment.
Zeroing the Power Sensor
1. Ensure that the power sensor is not connected to any signals.
2. Zero the power sensor using the built-in function, according to the power sensor
documentation.

Characterizing Power Splitter Amplitude Balance and
Loss
This procedure characterizes the amplitude balance of the two output ports of the power
splitter and amplitude loss through the power splitter over a range of frequencies.
The results of the characterization are later used as a correction in the following procedures:
•Verifying 50 Ω Passband Amplitude Flatness and Bandwidth
•Verifying 1 MΩ Passband Amplitude Flatness and Bandwidth
•Adjusting 50 Ω Passband Amplitude Flatness and Bandwidth
•Adjusting 1 MΩ Passband Amplitude Flatness and Bandwidth

1. Connect the calibrator test head to channel 0 of the PXIe-5164.
2. Configure the PXIe-5164 with the following settings:
• Input impedance: the Input Impedance value from the DC Accuracy Verification
table
• Maximum input frequency: (1 MΩ) 300 MHz, (50 Ω) 400 MHz
• Vertical offset: the Vertical Offset value from the DC Accuracy Verification table
• Vertical range: the Vertical Range value from the DC Accuracy Verification table
1Measurement uncertainty based on Fluke 9500B with Fluke 9530 test head specifications that
apply at Tcal ± 5 °C, where Factory Tcal = 23 °C. Uncertainty of the 9500B includes long-term
stability of 1 year, temperature coefficient, linearity, load, and line regulation and traceability of
factory and National Calibration Standard.

• Sample rate: 1 GS/s
• Minimum number of points: 8,500,000 samples
• NI-SCOPE scalar measurement: Voltage Average
3. Configure the calibrator output impedance to match the impedance of the PXIe-5164.
4. Configure the calibrator to output the Test Point value from the DC Accuracy Verification
table.
5. Enable the calibrator output.
6. Wait one second for settling, then record the measured voltage.
7. Use the following formula to calculate the voltage error:
DC voltage error = Vmeasured - Test Point
8. Compare the voltage error to the appropriate limit from the DC Accuracy Verification
table.
9. Repeat steps 2 through 8 for each configuration listed in the DC Accuracy Verification
table.
10. Disable the calibrator output.
11. Connect the calibrator test head to channel 1 of the PXIe-5164 and repeat steps 2 through
8 for each configuration listed in the DC Accuracy Verification table.
12. Disable the calibrator output.
Verifying AC Amplitude Accuracy
Follow this procedure to verify the AC amplitude accuracy of the PXIe-5164 by comparing the
voltage measured by the PXIe-5164 to the voltage measured by the DMM.

2Measurement Uncertainty is based on the following equipment and conditions:
• NI PXI-4071 specifications apply after self-calibration is performed and in an ambient
temperature of 23 °C ± 5 °C.
• The cable from the BNC Tee to the DMM must be 1 meter or less.
• Pasternack BNC Tee PE9174.
